2 How to use this catalogue This catalogue has been designed to enable users to access the information on the whole product range in a straight-forward and logical manner. We are conscious that the needs of our customers vary considerably and that, as our markets continue to grow, many will be dealing with our systems and products for the first time. Where product codes are already well known, the Product and Parts Locator at the back of the catalogue will direct you to the pages relevant to each occurrence of a particular item. Each main product or system category has its own section. The sections are arranged such that those detailing the simpler and smaller systems are at the beginning. Exploded views of typical system configurations are given as a guide, near to the front of each section. In order to help you to build a system, there are detailed Selection Charts at the end of each section. Again, these are formatted in a logical manner, from main housings to incomers, outgoing devices to their accessories. Once a reasonable level of familiarity with the TE Connectivity Dorman Smith product range has been attained, complete circuit distribution systems can be readily configured directly from the Selection Charts alone. Following the main products sections, the Technical Data and Applications section provides a high level of detail on both specific products and the principles of circuit protection in general. We trust you will find this catalogue informative, helpful and a quick and easy-touse tool whenever you need to configure MCB or MCCB distribution schemes.

58 Loadbank 200 Metering Selection Loadbank 200 The Loadbank 200 metering facilities utilise standard cableway extension enclosures with optional door kits designed for panel mounted meters. The size of the cableway will determine the corresponding metering door kit. Where cable sizes exceed 70mm a recommendation would be to include two cableway extension enclosures to facilitate easy wiring. The same could be advised when fully populating an 18 way panel board with meters. Current transformers and fuses can be DINrail mounted within the cableways using the facilities provided within the optional door kits.

82 Loadbank 250 Meter Selection Process Loadbank 200/250 The Loadbank 200/250 metering facilities utilise standard cableway extension enclosures with optional door kits designed for panel mounted meters. The size of the cableway will determine the corresponding metering door kit. Where cable sizes exceed 70mm a recommendation would be to include two cableway extension enclosures to facilitate easy wiring. The same could be advised when fully populating an 18 way panel board with meters. Current transformers and fuses can be DINrail mounted within the cableways using the facilities provided within the optional door kits. Panel-board enclosures Description Cat. no.

136 Compliance with International Standards Dorman Smith branded products comply with internationally recognised technical and quality standards to ensure that each product is fully capable of meeting the relevant standard requirements for its intended use. The design, manufacture, procurement, supply and servicing of Dorman Smith branded products is also governed by compliance to an international standard through the operation of a Quality Management System. Quality Management System BS EN ISO 9001:2008 The Institute of Electrical Engineers (IEE) British Standard BS 7671 addresses Requirements for Electrical Installations and dictates that all relevant products must comply with applicable British, International or Harmonised Standards according to the intended installation and application of the equipment. The BS 7671 document is commonly referred to as The Wiring Regulations. Products are type tested, manufactured, routinely tested and assembled in accordance and compliance with a number of relevant Harmonised Standards recognised by the electrical industry. A Harmonised Standard is a European Standard formally presented by the European Committee for Electrotechnical Standardisation, CENELEC, to the European Commission and published in its official journal. These documents are denoted by the prefix EN (European Norm). The products listed within this catalogue conform to appropriate electrical and mechanical standards as follows: MCB Distribution Boards EN Panel Boards EN MCBs EN MCCBs EN Switches EN RCCBs EN RCBOs EN Contactors EN In addition to the above, and where appropriate, Dorman Smith branded products also comply with the relevant requirements of the standard for protection against physical, mechanical and liquid ingress as follows: Ingress Protection EN

137 Standard Terminology The Harmonised Standard EN and the IEE Wiring Regulations BS 7671:2008 contain references to a set of adopted standard terminology for the principal device parameters with regard to MCBs. This terminology is also embraced by other standards with regard to MCCBs and switches (EN and EN ). The standard terminology relates to the following parameters: Rated Operational Voltage, U e Rated Insulation Voltage, U i Rated Current, I n Rated Short Circuit Capacity, I cn Rated Service Short Circuit Breaking Capacity, I cs Rated Ultimate Breaking capacity, I cu Rated Voltage and Current Rated Operational Voltage, U e The nominal voltage of the system should not exceed the stated value of U e. For example: single-pole U e = 230/400V, three-pole U e = 400V. The standardised values of 230V and 230/400V will progressively replace 240V, 220/380V and 240/415V. Rated Insulation Voltage, U i This is the voltage upon which the dielectric properties are based, using tests at high voltage and mains frequency. Unless otherwise stated, the rated insulation voltage is the value of the maximum rated voltage of the circuit breaker. In no case shall the maximum rated voltage exceed the rated insulation voltage. Rated Current, I n This is the current that the circuit breaker will carry continuously under specified conditions and upon which the time/current characteristics are based. Unless otherwise stated, this value is based upon a reference ambient temperature of 30 degrees Celsius. EN Standard refers to the following terms: Short Circuit Capacity Rated Short Circuit Capacity, I cn The calculated prospective fault current at the incoming terminals of the circuit breaker should not exceed the stated value. For example: I cn = 10kA (marked 10000). Service Short Circuit Breaking Capacity, I cs This value is the maximum level of fault current operation, after which further service of the device is assured without loss of performance. Note that there is no requirement for I cs to be marked on the device. There is a proscribed relationship between I cs and I cn, as follows: For values of I cn up to 6000A I cs = I cn For values of I cn 6000A to 10000A I cs = 0.75I cn (but with a minimum value of I cs = 6000A) For values of I cn above 10000A I cs = 0.5I cn (but with a minimum value of I cs = 7500A) 135

138 The EN and EN Standards also refer to the following terms. Isolation Suitability These define the requirements for the suitability of circuit breakers to perform isolation duty by defining tests to which such units must comply. Conforming devices must carry a standard symbol mark to show that they are suitable for isolation duty. For example, all Dorman Smith circuit breakers are so marked. Utilisation Categories The utilisation category of a circuit breaker is stated with reference to whether or not it is specifically intended for discrimination by means of an intentional time delay with respect to other circuit breakers in series on the load side under short-circuit conditions. Category A This designates circuit breakers not specifically intended for selectivity with devices on the load side. Circuit breakers will discriminate only up to certain fault levels, above which discrimination with devices on the load side cannot be guaranteed. Category B This designates circuit breakers specifically intended for selectivity with devices on the load side. Such circuit breakers will incorporate some form of time delay. EN recognises both a rated service and a rated ultimate short circuit breaking capacity for both Category A and Category B circuit breakers. Rated Service Breaking Capacity, I cs In order to define this value, the circuit breakers under test must be subjected to a test sequence of: I cs = o t co - t co, where: o = opening time under fault conditions t = time interval before re-closing (not more than 3 minutes) c = closing operation on to a fault After this test sequence, dielectric, terminal temperature and over-current tests are to be applied. The circuit breaker must meet certain test parameters to ensure that the device has not deteriorated in performance and can be put back into service. Rated Ultimate Breaking capacity, I cu In order to define this value, the circuit breakers under test must be subjected to a test sequence of: I cu = o t co. After this test sequence, dielectric and over-current tests are to be applied. The rated service breaking capacity (I cs ) applies to short circuit faults that could occur in practice; whereas the ultimate short circuit capacity (I cu ) is the maximum theoretical fault value of the installation at the point of connection. The standard defines the ratio between the two values. I cs will be shown as 25%, 50%, 75% or 100% of its I cu value for Category A devices and 50%, 75% or 100% of I cu for Category B devices. A circuit breaker can remain in service after interrupting a short circuit up to its rated value of I cs. However, where two or more faults occur between the I cs and I cu values, the capability of the device for continued operation must be verified. 136

139 Current Carrying and Switching Devices Switch A switch is a mechanical device capable of making, carrying and breaking current under normal circuit conditions. Disconnector (Isolator) A disconnector is a mechanical switching device that provides the function of circuit isolation. Switch Disconnector This device combines the functionality of the two foregoing devices; it provides making, carrying, breaking and isolation of current within a circuit. Fuses Fuses can be combined with any of the above devices in any physical order. The inclusion of a fuse will add the functionality of short circuit protection, breaking the circuit when the current flow is higher than that for which the circuit is rated. Combination Devices In order to enhance circuit protection, switches and fuses are often combined within a single device. The physical composition of the device can be identified by the literal position of the words in its description. For example, the word fuse at the beginning of the device description identifies the fuse as forming part of the moving contact system, whereas placing it at the end of the description identifies the fuse as a static link. Functional Summary Term Features Features provided not provided Switch Current rating Isolation Operational and insulation voltage Protection Making and breaking of load Short time current rating Disconnector Current rating Protection Isolation Making/breaking capability Operational and insulation voltage Short time current rating Fuse Overload protection Switching Short circuit protection Suitability for Purpose All of these devices have the ability to carry rated current either continuously or for a period of eight hours under defined conditions. Selection and specification of a specific device depends upon the circuit application. 137

140 Function Switching Applications For switching applications, the principal functions and capabilities include: Making and breaking operation A switch must have the ability to make or break defined load and overload currents at a rated operational voltage, for the useful life of the device. Short circuit action The device must have the capability of handling short circuit current and/or through fault and/or fault making. Protection The device must interrupt the circuit under overload and/or short circuit conditions. Isolation To meet this requirement, the device must ensure disconnection of the supply for safe downstream working. Facilities must be included for safety padlocking in the off position, together with positive indication of the contact position. Neutral switching Where the neutral is reliably earthed, it is accepted that the neutral need not be switched except in defined circumstances (e.g. the incoming switch disconnector in a consumer unit) even though the Wiring Regulations (BS 7671:2008) class the neutral as a current carrying conductor. In applications where the neutral cannot be confirmed as reliably earthed, the neutral should be switched simultaneously with the phase(s) or alternatively arranged to make before and break after the phase(s).

Category AC20/DC20 AC21/DC21 AC22/DC22 AC23/DC23 Circuit/application Connecting and disconnecting under no load. Assumes all switching operations are carried out by other capable devices before this device is operated. Switching of resistive loads including moderate overloads. Suitable for purely resistive type loads. Device can switch 150% of its rated current under fault conditions. Switching of mixed resistive/inductive loads, including moderate overloads. Suitable for mixed resistive/inductive loads. Device can switch 300% of its rated current under fault conditions. Switching of highly inductive loads. These devices are provided principally as back-up to other means of switching, e.g. contactors. In the event of failure of the functional device, the AC23/DC23 device can safely interrupt a stalled motor current. Where devices are the only means of controlling individual motors they should comply with the requirements of Appendix A of the EN standard. Note: Switch disconnectors for AC21/DC21, AC22/DC22 and AC23/DC23 categories also have to meet the requirements of AC20/DC20. For specific and special applications such as switching of capacitors and tungsten lamps not covered by the EN standard, the manufacturer s advice should be sought. Frequent and Infrequent Use The designation A or B should be appended to utilisation categories to indicate the suitability for frequent or infrequent use in service. The Rule of Thumb definition for full load current switching duty is: Frequent (A): Up to five times a day for small devices, say up to 100 amps, and once per week for larger devices. Infrequent (B): One per week for the smaller devices and once per month for the larger devices. 139

142 Miniature Circuit Breakers (MCBs) In general terms, circuit breakers are thermal/magnetic electromechanical devices that provide current making, carrying and breaking functions and will trip to interrupt a circuit under abnormal conditions. MCBs are equipped with positive contact indication flags: red indicates that the contact(s) are closed, green indicates the open state. The contact(s) will open when tripped due to abnormal circuit conditions or can be manually put into the open state by use of a handle. These devices are used to provide protection and control of circuits against overload and short circuit conditions. Dorman Smith MCBs are supplied with various breaking capacities, particularly for ratings of 6kA and 10kA. The lower rated devices are used typically in domestic installations, e.g. in consumer units, whereas the higher rated devices are suitable for a range of commercial and industrial circuit protection applications. The thermal and magnetic trip functions cater for different circuit abnormalities and operate as follows: Thermal Trip Function The purpose of this form of protection is to interrupt the circuit upon sensing an overload current. Typically, a bi-metallic strip is used such that it will deflect due to differential expansion of the dissimilar metals in response to the heating effect caused by the passage of current through it. The higher the current, the greater will be the heating effect and the more the deflection. At a preset point the physical deflection will be sufficient to actuate the tripping mechanism, opening the contact(s) and interrupting the circuit. Magnetic Trip Function The purpose of this form of tripping is to protect against the effects of short circuit fault currents. A wire coil or solenoid is used to provide this function, operating the trip mechanism when the over-current reaches a preset magnitude. As the fault current rapidly increases, the magnetic field also increases, energising the coil and moving a cam that is part of the contact assembly to fully open the contact(s) thereby interrupting the circuit. Characteristics MCBs are designed according to one of three distinct tripping characteristics designated B, C or D. These designations relate to the magnetic trip setting and indicate the multiple of nominal current that will be tolerated by the device before tripping. The following table illustrates these characteristics with typical duties and applications. The nominal rated current is denoted by the symbol In. Type Magnetic Application trip B 3-5 In Light duty, resistive loads C 5-10 In Fluorescent lights, small motors, inductive loads D In Sodium lights, large motors (>3kW), large inductive loads 140

143 MCB Tripping Characteristics B, C and D Types B C D The tripping time for the thermal release is defined according to specific values of applied overload current, as follows: Text current Tripping time 1.13In >1h (In < 63A) >2h (In > 63A) 1.45In <1h (In < 63A) <2h (In > 63A) 2.55In 1s<t<60s (In < 32A) 1s<t<120s (In > 32A) MCB Add-on Functions Various accessories can be added to MCBs to enable remote access and signalling. For example, the contact status could be relayed to an alarm annunciator panel or SCADA system; the circuit breaker could be controlled also from the SCADA system. Auxiliary Contacts Relaying of contact status can be achieved by the addition of an auxiliary contact and the contact form selected to suit the remote system input requirements. Shunt Trip The addition of a shunt trip allows remote access to the breaker operation, permitting the supervisory system to manually trip the breaker. The shunt trip actuator is a coil that is normally de-energised in the closed (on) state. When activated, the shunt trip will force the breaker to its off state and the toggle handle and indicator flag will move to this corresponding position. Since the fail-safe (i.e. non-powered) state of a shunt coil is with the breaker remaining closed, this precludes its use for emergency stop purposes. The interconnecting wiring could be open-circuit, for example, and would therefore not allow the shunt to open the breaker when the remote emergency switch is closed. Under-voltage Release If the supply voltage dropped to a low level and devices tripped, a dangerous situation could exist if the devices were automatically reset. For example, motors could suddenly restart or other operating machinery set in motion without warning. In the event that the mains voltage should drop significantly below its normal operating range, typically to less than 50%, an under-voltage release will force the breaker to its off state and the toggle handle and indicator flag will move to this corresponding position. Only when the supply has returned to, typically, at least 85% of normal operating voltage will the under-voltage release allow the breaker to be closed. If a break occurred in the interconnecting wiring in this case, the breaker would be tripped, just as if the voltage had fallen below the threshold value. For this reason, it is advisable to include an alarm function when using a UVR function. 141

144 I I Energy Let-through An important facet of circuit protection devices is the extent to which they limit the amount of electrical energy they allow to pass through them. This applies to fuses as well as to circuit breakers. When an electric current flows through a resistance for a certain time, energy is produced in the form of heat. This thermal effect can be measured using the formula: I 2 x R x t, to give a quantity in Watt seconds. The unit of measurement for energy is the Joule, which is equivalent to one Watt second. For all practical purposes, the resistance is treated as constant and negligible; therefore the commonly accepted term for energy let-through of a device is I 2 t since this will always be proportional to the true thermal effect. The I 2 t term is referred to as the Joule Integral since the results are expressed in integral form. Under short-circuit fault conditions there is the potential for considerable energy to be let through by a circuit protection device. Knowledge of the energy letthrough characteristics of circuit protection devices is useful for comparison between different devices and also with regard to the selection of devices that are required to act in co-ordination to produce the levels of discrimination required for fault clearance. The I 2 t characteristics of circuit breakers are depicted as curves, graphed against values of prospective short-circuit current. These characteristics are relevant to both MCBs and MCCBs as depicted in the following graphs.

145 Within the EN standard, circuit breakers with B and C characteristics are categorised into energy limiting classes 1, 2 and 3, with Class 3 denoting devices having the lowest energy let-through. The appropriate energy class is marked within a square box on conforming devices. Dorman Smith MCBs are categorised within Class 3. The following table indicates the maximum energy let-through values permissible in each class, stated in Watt-seconds. In practice, compliance with the standard is checked on the circuit breakers with the highest applicable rated current within the range, normally 40A.

147 Residual Current Circuit Breakers Currents of low magnitude caused by unintentional leakage paths to earth can cause deterioration within circuit wiring and components with the potential to create a rapidly escalating situation that will permit the current to reach dangerous levels. Special forms of circuit breakers are designed to use the detection of earth leakage or residual current to limit the effects of this type of fault. The generic term residual current device is used to describe a range of circuit protection devices that include the functions of sensing and measurement of a leakage current, with subsequent tripping when the magnitude of the residual current reaches a preset level. The purpose of these devices is to protect human life, livestock, property and equipment against the escalation of earth fault currents to destructive magnitudes. Two forms of technology are commonly employed in the design of residual current devices; electromagnetic and electronic. In both cases, a current transformer is used and is arranged such that normal current flows in the phase and neutral conductors cancel each other to produce a zero balance. The presence of any residual current will create an out-of-balance that can be used to signal the actuation of a mechanism for circuit interruption. In the electromagnetic type, a trip relay is used as the actuation device. The relay is powered by the fault current and therefore requires no external power source. With electronic devices internal signal amplification allows a much smaller current transformer to be used, reducing the physical size of the circuit breaker. In this case, however, the actuation power is derived from both the fault current and the mains power. Also, a separate earth reference connection may be required to ensure continuity of operation in the event that the mains neutral is lost. Residual current devices are accorded a sensitivity coding that indicates the level of residual current that would cause a trip action. Commonly, the available sensitivity ranges are 10mA, 30mA, 100mA and 300mA. In general, the 10mA and 30mA devices are used to protect human life, the 100mA and 300mA devices being applied to protect wiring, cabling and equipment. The degree of electrocution that could take place when a fault arises depends upon the combined effects of the magnitude and duration of current flow. For sensitivity levels of 30mA and below, tripping must be instantaneous to protect human life. Longer periods of residual current flow can be tolerated by equipment and the trip action may not necessarily be required to interrupt the circuit instantaneously. Residual Current Circuit Breaker The RCCB device combines the functions of a switch with those of a residual current device. It is often used in place of an incoming switch disconnector with the advantage that it functions also as a residual current protection device. The disadvantage, however, is that a residual fault will cause the device to operate interrupting ALL downstream circuits even when these circuits remain in a healthy state. Note that an RCCB should not be used as the sole means to provide complete protection. It has no overload or short circuit protection and must therefore be further protected by an upstream device having these capabilities. Frequently, the RCCB is used in consumer units and distribution boards to protect sub-circuits in a split load configuration. In these applications, the upstream back-up is provided by the Regional Electricity Company s local fuse. Residual Current Breaker with Overload Protection The RCBO combines the functions of an MCB with those of a residual current device. It will therefore provide protection against overload, short circuit and earth leakage. 145

148 RCBOs and RCCBs General These devices are furnished with a test pushbutton on the front face of the module. Operation of this button will simulate the presence of a residual fault and the test should be made frequently, say once per month, to assure continued correct functionality of the device. In addition to the range of sensitivities, RCBOs and RCCBs are available in two types, type AC and type A. These refer to the types of circuit for which the devices are suitable. Type AC: for use with residual sinusoidal ac, whether applied as a step or ramp. Type A: for use with either residual sinusoidal ac or residual chopped (pulsating) dc, whether applied as a step or ramp. A time delay facility may also be included, adjustable up to, typically, 50-70mS. This is denoted by S included within the description and also marked on the device. This function is included in order to enable the device to be used as part of a circuit device discrimination (or selectivity) arrangement. Without the time delay, residual current circuit breakers cannot be easily used within a discrimination scenario due to their inherent rapid tripping in response to residual current detection. Whereas RCBOs are single module width devices used in place of or alongside MCBs in outgoing circuits, RCCBs are available in 2-pole and 4-pole forms and are readily used in single phase and three phase distribution systems where they can function as either incoming or outgoing ways. Due to their low levels of sensitivity RCCBs are generally equipped with suppression filtering to avoid nuisance tripping that could be induced from disturbances in external or incoming circuits. 146

149 Modular Contactors Contactors are simply electromechanically controlled switches. A contactor acts as an interposing relay which, when its coil is energised, operates one or more sets of contacts that are able to carry currents of sufficient magnitude to switch power equipment such as large banks of lights, highly inductive lamps, motors and large solenoids. The current required to operate the coil is minimal, therefore a contactor can be controlled by light duty contacts in a timer, pushbutton or other control device. Generally, contactors have no latching facility, i.e. once the coil is de-energised the contact state returns to its normal condition. However, whilst there is no mechanical latching, electrical latching can be easily accomplished by using a separate relay contact to hold on the supply to the contactor s coil. Selection Criteria The correct choice of contactor depends upon a number of parameters within the intended application. These include: The form of power supply The magnitude of the power to be switched The type of load to be controlled The control voltage required The frequency of switching Since the device operates by its coil being energised for possibly lengthy periods, considerable internal heat can be generated. For this reason, a venting insert must be placed between alternate pairs of contactors or between a contactor and any other adjacent circuit device. Switching Capacity Contactor ratings are stated for AC1 type loads only (resistive). Where the load to be switched differs from this, it is likely that the contactor will have to be de-rated to ensure its performance. If the load is dc, inductive or capacitive, the degree of de-rating may be considerable. The following contactor de-rating tables indicate the maximum power/current that can be switched according to the type of load to be controlled. The figures quoted are per phase and are based upon a 230V ac supply. 147

153 Moulded Case Circuit Breakers The operation and application of the MCCB is similar to that of the MCB, however this device has the air-break mechanism contained within a moulded case housing made from a very robust non-conducting material. Generally, MCCBs exhibit much higher breaking capacities and rated current than their smaller counterparts and can be used to perform full isolation duty. Consequently, MCCBs are employed in both incoming and outgoing circuits. MCCBs are constructed to a particular frame size and typically provide rated current in the range A. These devices can be equipped with adjustable thermal and magnetic tripping mechanisms to cater for overload and short circuit protection to meet the requirements for isolation and Category A discrimination duty. Dorman Smith electronic MCCBs provide adjustable long, short and instantaneous trip functions, allowing more complex overall tripping characteristics to be configured, allowing these devices to be used for isolation and Category B discrimination requirements. (Refer to page 136 for Category definitions). Devices equipped with the full range of adjustable trips for long, short and instantaneous durations are generally referred to as LSI-MCCBs to distinguish them from the L and I only versions employed for Category A devices. The range of accessories that can be added to MCCBs is similar to that given in the section dealing with MCBs, including shunt trips, under-voltage releases and various forms of auxiliary contacts. The physical size of triple-pole and four-pole MCCBs allows these accessories to be internally mounted, although there are some restrictions with regard to combinations of these that can be co-mounted. For example, either a shunt trip or under-voltage release can be incorporated, but not both. Also, due to the much larger physical size of these devices compared with MCBs, additional safety features normally include interphase barriers and terminal shrouds to provide IP2X ingress protection at the terminals. The tripping operation of some MCCBs is different from that of MCBs in that there are three distinct positions of the toggle or handle. Whereas MCBs are either on or off, MCCBs have a central position when they are tripped. As a further safety feature, the coloured flags indicating the on and off states are masked in the tripped state. The breaker can be reset only after it has been set into the fully off state. MCCBs are equipped with a test pushbutton that allows periodic testing of the mechanical tripping mechanism. As in the case of a fault trip, the device must be moved into the off position before it can be reset following a test. These devices conform to EN therefore the definitions that apply to some parameters differ from those of EN that apply to miniature circuit breakers. These differences are explained in the section covering Standard Terminology. Motor Control Applications The MCCB is a viable means of providing motor control switching. However, MCCBs used for this type of application are often required to provide only short circuit protection, with the overload protection catered for by a separate thermal or electronic overload relay. For this reason, specifically designed motor control MCCBs are available upon request, with only the single tripping mechanism. The range of circuit breakers for each frame size includes a basic switch disconnector version, generally in both triple-pole and four-pole variants. Devices of this type are sometimes referred to as non-auto MCCBs. 151

155 Discrimination In the context of power distribution schemes, the term discrimination (sometimes referred to as selectivity ) describes a hierarchy of circuit devices that are arranged such that a single upstream circuit breaker can fan out to several downstream devices to act in a co-ordinated fashion should a fault occur. Under fault conditions, only the upstream protective device closest to the fault should operate to clear the fault, leaving all other healthy circuits operable. This is especially important in installations where circuit failures could be life-threatening, such as in hospitals. The concept of discrimination is similar to that of cascading, the prime difference being in the objectives of the application. Whereas discrimination is used to ensure continuity of supply to sub-circuits by limiting the disconnection to the faulted sub-circuit alone, cascading is used to buffer downstream protective devices against the effects of high prospective short circuit currents. In both cases, the protective devices are specifically selected to meet the criteria for the type of co-ordination required. When the selected devices are properly matched to fulfil the ideal discrimination principle described above, the co-ordinating devices are said to achieve total discrimination. In many practical installations, however, a partial discrimination may be satisfactory for safe continuity of supply, with an added advantage of cost savings due to selecting a lower rated upstream circuit breaker. Discrimination between two circuit breakers arranged in series may be based on either current or time. Where the magnitude of the fault current is to be used as the critical factor for selection, the co-ordination in this case is termed current discrimination. Where the basis for selection is the duration over which the upstream device can withstand the fault current, the selection is to achieve time discrimination. In some cases, time discrimination can be achieved by using an upstream device that has a built-in time delay. Current Discrimination In general, the basis for current discrimination is that the downstream protective device will have a lower current rating than the upstream device. It should also have a lower instantaneous tripping point. The discrimination tables that follow highlight the consequential increase in discrimination level as the differential in current ratings between the devices increases. Time Discrimination Discriminating by time between two devices in series relies on the operation of the upstream device being delayed at least until the downstream circuit breaker has tripped to clear the fault. The clearing time of the downstream device must be less than the time setting of the upstream device and the upstream device must also be capable of withstanding the fault current for the full duration of its time setting. There is generally no problem in achieving these conditions where the upstream device is a Category B circuit breaker specifically designed for this type of co-ordination duty. Time/Current Characteristics Comparison of the time/current characteristic graphs of the two devices proposed can give a quick check on their suitability for co-ordination in both current and time discrimination cases. Ideally, there should be no overlap of the respective curves to achieve total discrimination. If, however, the instantaneous portion of the curves do intersect, a partial discrimination will be achieved at the current level projected from the intersect point. In the tables that follow, total discrimination is indicated by the letter T in appropriate boxes. Total discrimination applies for all fault levels up to the lower breaking capacity of the two devices in co-ordination. Where a value is contained in any of the boxes, this indicates a partial discrimination of that value of current limit. If no discrimination is possible, this is shown by a dash symbol. 153

156 Note that partial discrimination infers that, above the current limit value indicated, it is possible that both devices could trip, resulting in disconnection of other sub-circuits and loss of supply continuity to those areas of the distribution system.

159 Cascading Cascading is sometimes referred to as back-up protection. The technique of cascading is used to allow circuit breakers with a breaking capacity lower than the value of prospective short-circuit current at the connection point to be used when these are positioned downstream of a current-limiting circuit breaker of higher breaking capacity. The net result of this arrangement is that the downstream device acquires an enhanced installed breaking capacity, therefore a less expensive, lower breaking capacity breaker can be used. The upstream circuit breaker must have the normally required breaking capacity for its point of installation however, when combined with another circuit breaker downstream, the two devices in series will be able to clear a larger fault. For example: if a 10A, 6kA MCB is place downstream of a YA frame MCCB rated at 125A and 25kA, the MCB will have an installed breaking capacity of 14kA. Similarly, a 10A, 10kA MCB downstream of a YA frame MCCB rated at 250A and 25kA will have an installed breaking capacity of 25kA. It should be noted that the cascading technique is not limited to only two devices in series. The important point is that it is the upstream device that is limiting the current to a value that can be interrupted by the following device, so that the pattern of paired devices can be repeated many times in an hierarchy of devices. The following tables give installed breaking capacity values of downstream circuit breakers for both the MCCB/MCB and MCCB/MCCB pairings of cascaded devices. Note that all values shown are at 400V ac. The values for the installed breaking capacities are given in ka.

161 Short-circuit Discrimination Levels Where a high prospective fault level exists at the MCB distribution point, discrimination at short-circuit levels should be considered. This will require comparison of the device I 2 t characteristics at the relevant prospective fault level. Discrimination will be obtained at all fault levels for which the MCB total operating I 2 t is lower than the pre-arcing I 2 t of the device closer to the supply. The data for typical cartridge fuses can be extracted from graphs and is presented in the following tables. MCB, type B Fuse Current sizes rating (A) MCB, type C Current rating (A) MCB, type D Current rating (A)

162 System Sizing and Diversity The adequacy of sizing and rating of power distribution systems is important to ensure supply continuity and safety in operation. A number of design parameters must be taken into account in order to ensure that the supply and safety requirements are met. These include busbar ratings, short-circuit fault levels and circuit utilisation. Once the overall loading requirements have been established, and the supply transformer selected, consideration of the circuit distribution systems follows. Distribution enclosures and their busbar systems are pre-tested to accepted norms of through-fault levels, typically 16kA, 25kA, 35kA, 50kA and 80kA. These shortcircuit ratings alone will limit the choice of switchboard, panel board or distribution board. The selection of the type and size of enclosure to be used will then depend upon the busbar current rating needed, together with availability of sufficient circuit ways of the correct type for the circuits and sub-circuits to be supplied. The busbar current rating is generally chosen to be sufficient to supply full load, plus some safety factor. For example, if the full load is expected to be 750 amps, an enclosure with a busbar rating of 800 amps may be selected. Once the busbar current rating has been nominated, the incoming device for that group of circuits will be matched to the rating. In the example cited, the incoming device would be rated at 800 amps. More than one incoming device may be required to effect proper circuit protection and isolation, such as a switch disconnector in series with a thermal fuse. In this case, the fuse link will provide the protection and the disconnector will permit isolation. Alternatively, a moulded case circuit breaker (MCCB) employed as the incoming device will provide both protection and isolation. The size and type of circuits to be supplied will further refine the eventual choice of distribution system. Automatic or manual circuit disconnection will point to an enclosure suitable for either circuit breakers or switch-fuse devices. If the requirement is for automatic disconnection, prospective fault levels at the connection point may dictate that an MCCB must be used, rather than an MCB of the same current rating. Finally, consideration is given to the degree of circuit utilisation capacity, often referred to as diversity. Notwithstanding the limitations of the busbar system and the matched protection provided by the incoming device, the outgoing circuit ways may be configured with individual circuit protection devices having an aggregate rated current capacity in excess of the rating of the incomer. The basis for this approach is that it is often reasonable to assume that not all circuits will be supplying their rated current at the same time. In this case, a diversity factor is applied during the design stage to give an overall service capacity for the outgoing circuits. The maximum current rating divided by the diversity factor will give the maximum aggregate fitted current allowed. The following table lists the factors that may be applied subject to the number of outgoing circuits to be supplied. Taking the example of a 400A panel board with 400A MCCB incomer and 6 outgoing circuits, a diversity factor of 0.7 would allow outgoing MCCBs with an aggregate of 570A capacity to be installed. The individual circuits would be protected at the level of current rating of each MCCB, with the incomer providing ultimate protection at 400A. To allow for the possibility of future expansion of a distribution system, an allowance for 25% spare capacity is often included when applying a diversity factor to the initial design.

163 Prospective Short-circuit Current The Prospective Short-circuit Current, or PSC, is the theoretical maximum fault current that could exist at any point within a complete circuit distribution system. The magnitude of the fault current at any particular point is calculated on the basis of a bolted (virtually permanent) fault path at that point and therefore assumes a constant voltage, continuous current supply feeding the fault. Using this assumption, the PSC that could possibly exist at the bolted fault path would be limited only by the sum of the circuit impedances of the complete current path, from high voltage feed to the supply transformer through to the bolted connection point. Since this assumption cannot be fulfilled in practice (for example, the voltage will not remain constant) the value of calculated PSC can never be exceeded in a practical scheme. The foregoing commentary is particularly relevant to larger commercial and industrial networks, where many sub-systems are present and often, many sub-circuits within these. For more compact arrangements, such as domestic installations, where the distribution scheme is contained within one or more consumer units, the situation is much simpler. The Regional Electricity Companies generally agree on a fixed fault level of 16kA at the local zone supply distribution point to one or more dwellings. Those dwellings that lie some distance from the zone origin point of the distributed supply will have reduced PSC due to the higher impedance of the longer run of service cable. Consumer units should therefore have a minimum short-circuit rating of 16kA. When an MCB trips, the combination of forced contact separation and rapid arc extinction produces a limiting effect on the fault current such that it will be adequately handled within the normal 6kA breaking capacity of MCBs fitted to domestic installations. PSC at the origin point In practice and with consideration of the total distribution network; the breaking capacity of an individual circuit device would normally be less than that calculated for the origin point of the scheme. PSC at the connection point The breaking capacity of individual devices must be greater than (or at least equal to) the PSC at the specific point of their connection within a scheme. Conversely, where the circuit device breaking capacity is greater than the PSC at origin, there is no need for further measurement or calculation in this regard. The PSC at any particular connection point can be estimated, calculated, or determined by measurement of the circuit impedance at that point. Measurement of the circuit impedances at all relevant connection points can be a laborious exercise; the calculation method is generally used since this can be readily carried out using one of a number of available computer software packages. PSC by calculation The magnitude of the short-circuit current (rms value of the ac component) at the connection point will depend upon: the PSC at the origin point. the total resistance in the circuit between the origin point and the relevant circuit reference point. whether the short-circuit condition is considered as phase-phase, phase-neutral or phase-earth. The maximum PSC at the origin can be calculated from the following formula: PSC (ka) = Supply transformer rating (kva) x x secondary voltage x % transformer reactance PSC by estimation To estimate the PSC, first calculate the total resistance in the LV circuit by determining the sizes and lengths of cables between the supply source and the point under consideration. Next, use the following table to find the cable resistances and summate these to obtain the total resistance. Finally, use this value to read off the estimated PSC from the following graph. 161

165 PSC in a typical installation Note that the values on the graph assume a symmetrical fault across the three phases. In a single circuit, for line-neutral faults, the cable resistance value given in the table should be doubled. The following values of PSC would be obtained at the various circuit points marked in the above diagram: Point A PSC = approximately 27kA Point B Two cables per phase, therefore halve the value. Resistance from A to B = 0.3 Milli ohms With reference to the graph PSC can be assumed to be 25kA Point C Resistance from A to B = 0.3 Milli ohms Resistance from B to C = 10.7 Milli ohms Total circuit resistance A to C = 11.0 Milli ohms With reference to the graph PSC can be assumed to be 12kA Point D Resistance from A to B = 0.3 Milli ohms Resistance from B to C = 10.7 Milli ohms Resistance from C to D = 46.0 Milli ohms (Double the value for the 2-core cable) Total circuit resistance A to D = 57.0 Milli ohms With reference to the graph PSC can be assumed to be 3kA 163

166 Earth Fault Protection One of the most common means of protecting persons against the effects of high voltages and currents is by insulating the wiring and components. Most earth faults occur when some part of the insulation has broken down, creating the possibility of causing electric shock through indirect contact with the faulty circuit. The breakdown of insulation can often cause all or part of an enclosure or frame to become live by raising conductive parts to a hazardous voltage level. Touching any of the exposed parts of the enclosure or frame would then be highly dangerous and would most likely cause an electric shock. Whilst protective devices may open quickly to minimise the possibility of high currents flowing for any significant length of time, additional measures are necessary to limit the potential earth fault current at source. In some cases fault current limiting resistors or inductors may be installed at the transformer star point however, in all cases, it is important to ensure that the impedance of circuit conductors is kept to a minimum so that the voltage developed under fault conditions will be restricted. The earth fault loop impedance is denoted Zs and is an important circuit design parameter. Circuit designs must always ensure that the magnitude of the fault current will be sufficient to trip the over-current protective devices within acceptable times as stated in the IEE Wiring Regulations. Circuit breakers are designed to trip and therefore disconnect faulted circuits very quickly. The design value of tripping time is generally expressed in the form of a graph that maps current against time and any practical scheme can be checked against this value to ascertain conformance with the requirements. The fault current can be established very simply using Ohm s law, as follows: Fault current = Phase-to-earth voltage Zs Once this value is known, the corresponding tripping time can be read from the relevant device s time/current characteristic graph and the result compared with that given within the Wiring Regulations. In general, the higher the nominal voltage of an installation, the shorter will be the required disconnection time. For fixed equipment installations, the maximum disconnection time is stated as 5 seconds, whereas it is 0.4 seconds for portable equipment. The Regulations define portable as including fixed outlet sockets that may be used to supply apparatus that is movable or portable when in use. The following table illustrates the maximum Zs allowable for MCBs to achieve the specified disconnection times. Current rating (A) Type B max. Z s (ohms) Type C max. Z s (ohms) Type D max. Z s (ohms) Since the complete loop impedance is the sum of the individual impedances of the supply transformer winding, circuit phase conductor and protective circuit conductor, the total may be higher than that specified for in-time disconnection for the protection device proposed. In these cases, several solutions may be possible to overcome or at least assist in achieving compliance. The supply cable may be replaced by one with greater cross sectional area The short-circuit tripping threshold of the device may be set to a lower value (if it is adjustable) A Residual Current Device could be used to replace the circuit breaker in question The following tables indicate the maximum Zs for Dorman Smith s range of MCCBs. Using these tables obviates the need to determine the suitability of a device by reference to its time/current characteristic graph. 164

169 Forms of Separation The principle of separation applied to multi-cubicle switchboards and panel boards is the achievement of a high degree of safety for equipment and people during normal operation and to promote safe working during commissioning and service. The resulting concept is one of functional separation and segregation of live parts of the system into sub-units by the use of barriers or partitions. In general, separation should provide enhanced safety by: Protecting against contact with the live parts of adjacent functional units Preventing the passage of solid foreign bodies from one section of an assembly to an adjacent one Various elements of an assembly must be considered for separation from neighbouring live sections, such as busbars, terminals and functional units. The specific form of their separation can be achieved in several ways according to the particular application and the requirements for access for maintenance. The minimum degree of protection to be achieved at each barrier or partition is to IP2X as specified in the Ingress Protection standard EN Typically, this may include: PVC sleeving, wrapping or plastic coating of conductors Insulated terminal shrouds or PVC boots Rigid insulated barriers or partitions Compartments formed from earthed metal A device s integral housing There are several forms of separation, indicated by numbered category and subcategory; however the requirements for the degree of separation need to be carefully considered since the cost increases significantly with increased degree. The principal categories are: Form 1 no separation Typical applications are where the assembly is to be placed in a secure location and where failure will cause little or no additional disruption to other areas being supplied by that particular assembly. Form 2 separation of busbars from functional units Applications may be similar to those of Form 1 but where it is important that a fault need not affect all functional units being supplied by the same busbar system. Form 3 separation of busbars from functional units and the functional units from one another, but not their terminations This form should be applied where it is important to provide protection from internal live parts and where failure of functional units being supplied from the same busbar would cause unacceptable disruption. Form 4 separation of busbars from functional units and the functional units from one another, including their terminals This form should be applied where it is important to provide protection from internal live parts and where failure of functional units being supplied from the same busbar would cause unacceptable disruption. Because all the terminations are separated, it is possible to isolate and work on a single functional unit. Dorman Smith LF-type panel board systems are supplied in Form 2 as standard, with Form 4 versions achieved with simple conversion kits. However, other separation forms can be provided in special cases. With the exception of Form 1, the other separation forms have sub-categories that permit permutations of the general form to be configured according to the requirements for specific applications and to allow the accommodation of different types of protection method. The exact form of separation provided on an assembly is a matter for agreement between the manufacturer and the end user. 167

171 Ingress Protection The EN standard describes a system for classifying degrees of protection against the ingress of foreign bodies and harmful liquids. It is intended that this standard is applied to enclosures of low voltage (LV) electrical equipment. The classification scheme comprises a designation prefixed by the upper case letters IP, followed by two numerals. The first numeral designates the degree of protection with regard to solid objects; the second numeral indicates the degree of protection against the ingress of liquid. Compliance to the standard is intended to: protect persons against access to hazardous parts inside enclosures and protect the equipment inside the enclosure against the ingress of solid foreign objects. protect the equipment inside the enclosure against harmful ingress of liquids. IP Protection Equivalent 0 No protection 1 Full entry of 50mm Back of sphere, but no hand contact with hazardous parts 2 Full entry of 12.5mm Finger sphere not allowed, but no contact with hazardous parts with jointed test finger 3 2.5mm diameter Tool access probe shall not enter 4 1mm diameter access Wire probe shall not enter 5 Limited ingress of Wire dust (no harmful deposit) 6 Total protection Wire against dust ingress X Not tested - IP Protection Equivalent 0 No protection 1 Against vertically Vertical falling water drops drips 2 As in 1, but with Slanted enclosure tilted 15 dripping degrees from vertical to 15 degrees from vertical 3 Against spray to 60 Limited degrees from spray vertical limited ingress permitted 4 Against splashing Splashing from any direction from any limited ingress direction permitted 5 Against low pressure Hosing jets from any jets from direction limited any ingress permitted direction 6 Against strong jets Power from any direction hosing from any direction 7 Against immersion Temporary up to one metre immersion 8 Against prolonged Continuous immersion under immersion pressure X Not tested - For assemblies for indoor use where there is no requirement for the protection against ingress of water, the following IP codes are preferred: IP00, IP2X, IP3X, IP4X, IP5X, IP6X. 169

172 Insulation Distances for Loadline YA Frame MCCBs The insulation distances between an MCCB and adjacent earthed metal parts and insulators shown in the diagram below must be maintained to prevent arcing faults occurring due to conductive ionised gases. In cases where requirements differ from those illustrated here, the greater distance must be maintained. Where two different YA frame devices are installed one above the other, the insulation distance between the two should be as for the lower size of MCCB. Exposed conductors must be insulated up to the barrier terminals. Interphase barriers or terminal covers are recommended. However, if terminal covers are used, the exposed conductor must be insulated until it overlaps the terminal cover. 1. Insulation plate 2. Top plate (earthed metal) 3. Interphase barriers 4.
