65 Presentation TeSys contactors for the North American market, conforming to UL and CSA M Motor Disconnect (Disconnect switch) Motor Branch Circuit Protection (Short-circuit protection) Motor Controller (Contactor) Motor Overload Protection (Thermal overload relay) Starters for the North American market In recent years, the North American market has started to harmonise UL, CSA and ANCE standards, as well as the industrial installation codes provided by national regulations (NEC for the United States, CEC for Canada and MEC for Mexico). () Major improvements, carried out by the Canena () are aimed at harmonising product requirements based on IEC () standards. However, the North American codes use specific terminology for defining the functions of a starter. These functions can be fulfilled by standard IEC products, accompanied by appropriate certifications. Combination Starters Combination Starters are the most common type of packaged motor starter. They are called "Combination" because of their structure and their combined functions. The figure opposite shows the four combined functions that constitute a complete motor starter circuit, defined as a Motor branch circuit by the NEC (US National Electric Code) in article 0. Standard UL0 currently gives different types of combination starter that meet the requirements of a "Motor branch circuit". Type E, called self-protected combination starter, covers all these functions and can be controlled manually (thermal-magnetic circuit-breaker) or remotely (starter-controller). Type E starters withstand faults within their declared nominal rating without sustaining damage, after which they can be put back into service. In addition, they can withstand more severe short-circuit and durability performance tests without welding or excessive wear of the contact tips. Type F, called Combination motor starter, consists of a type E manual starter (thermal-magnetic circuit-breaker) combined with a contactor. These starters are evaluated by means of basic short-circuit tests, but are not considered as self-protected. For this combination, the type E starter must be marked Combination Motor Controller when used with..., followed by the reference of the load side contactor.

66 Presentation (continued) TeSys contactors for the North American market, conforming to UL and CSA Control panels To help users properly coordinate their motor control equipment with their distribution system in the event of a fault, article 09 of the 00 NEC requires panel builders to list the short-circuit withstand rating of their motor control panels. According to standard UL0A, manufacturers must use the short-circuit withstand value of the lowest rated device as the nominal withstand rating of the panel, unless the devices have been tested together for a higher coordinated rating. The minimum short-circuit current rating (SCCR), on motor control components for horsepower ratings of 0 hp or below is 000 A. Using a type E or type F combination starter eliminates the coordination problems of using individual components for the motor branch circuit protection, motor controller and motor overload protection functions. The panel builder uses the declared short-circuit current rating for the combination starter. This value is generally higher than 000 A. This makes it easier to list the short-circuit current ratings and to check the compatibility of a UL0A motor control panel within a given distribution system.

67 Presentation (continued) TeSys contactors for the North American market, conforming to UL and CSA Group protection Article 0. of the NEC allows a single short-circuit protection device to be used for more than one motor circuit if the components used are marked and listed for such use. Components suitable for use in group protection, known as motor group installations, can be marked in one of the following two ways: Case n The contactor and the motor overload relay are both listed as suitable for group installation. An inverse time circuit-breaker can be used as the short-circuit protection device if it is also listed as suitable for group installation. The panel builder must therefore make sure that the short-circuit protection device selected (fuses or inverse time circuit-breaker) does not exceed the value allowed by article 0.0 for the smallest overload relay used in the circuit. Once these conditions have been met, the panel builder can reduce the size of the conductor connecting the short-circuit protection device to the individual motor contactor/overload relay, to one third of the size of the upstream circuit conductor supplying the protection device. The panel builder must limit the length of the motor starter conductor (connecting the short-circuit protection device to the motor contactor/overload relay) to a maximum of. m ( feet). Case n The motor contactor and overload relay are listed as suitable for tap conductor protection in group installations. This category allows the panel designer to reduce the size of the conductor connecting the short-circuit protection device to the individual motor contactor/overload relay, to one tenth of the size of the upstream circuit conductor supplying the protection device. The designer must limit the length of this conductor to a maximum of.0 m (0 feet). In both cases, the supply circuits must not be less than % of the connected motor FLA (Full Load Amps) rating. For panel builders, using type F combination starters in group installations simpli es group motor considerations. Each starter is a fully coordinated motor branch circuit. The panel builder follows the same NEC requirements for sizing the supply conductors as those required for single motor branch circuits. The size of the supply conductors can be reduced in accordance with the speci cations of article 0.. This allows the same exibility in conductor sizing as that offered in article 0. (D), without a requirement to check the short-circuit protection rating marked on the components and the overload relay limit. A UL0A panel does not need a short-circuit protection device when each motor starter installed is a type F. The upstream short-circuit protection device supplying the starter protects the panel. The panel builder only has to consider the panel/enclosure disconnect requirements speci ed by the NEC or local codes.

69 General TeSys contactors Definitions and comments Definitions Altitude Ambient air temperature Rated operational current (Ie) Rated conventional thermal current (Ith) () Permissible short time rating Rated operational voltage (Ue) Rated control circuit voltage (Uc) Rated insulation voltage (Ui) Rated impulse withstand voltage (Uimp) Rated operational power (expressed in kw) Rated breaking capacity () Rated making capacity () On-load factor (m) The rarified atmosphere at high altitude reduces the dielectric strength of the air and hence the rated operational voltage of the contactor. It also reduces the cooling effect of the air and hence the rated operational current of the contactor (unless the temperature drops at the same time). No derating is necessary up to 000 m. Derating factors to be applied above this altitude for main pole operational voltage and current (a.c. supply) are as follows. Altitude 00 m 000 m 00 m 000 m Rated operetional voltage 0,90 0,0 0,0 0,0 Rated operational current 0,9 0,90 0, 0, The temperature of the air surrounding the device, measured near to the device. The operating characteristics are given : - with no restriction for temperatures between - and + C, - with restrictions, if necessary, for temperatures between - 0 and + 0 C. This is de ned taking into account the rated operational voltage, operating rate and duty, utilisation category and ambient temperature around the device. The current which a closed contactor can sustain for a minimum of hours without its temperature rise exceeding the limits given in the standards. The current which a closed contactor can sustain for a short time after a period of no load, without dangerous overheating. This is the voltage value which, in conjunction with the rated operational current, determines the use of the contactor or starter, and on which the corresponding tests and the utilisation category are based. For -phase circuits it is expressed as the voltage between phases. Apart from exceptional cases such as rotor short-circuiting, the rated operational voltage Ue is less than or equal to the rated insulation voltage Ui. The rated value of the control circuit voltage, on which the operating characteristics are based. For a.c. applications, the values are given for a near sinusoidal wave form (less than % total harmonic distortion). This is the voltage value used to de ne the insulation characteristics of a device and referred to in dielectric tests determining leakage paths and creepage distances. As the specifications are not identical for all standards, the rated value given for each of them is not necessarily the same. The peak value of a voltage surge which the device is able to withstand without breaking down. The rated power of the standard motor which can be switched by the contactor, at the stated operational voltage. This is the current value which the contactor can break in accordance with the breaking conditions speci ed in the IEC standard. This is the current value which the contactor can make in accordance with the making conditions specified in the IEC standard. This is the ratio between the time the current flows (t) and the duration of the cycle (T) Cycle duration: duration of current flow + time at zero current 9 Pole impedance Electrical durability Mechanical durability The impedance of one pole is the sum of the impedance of all the circuit components between the input terminal and the output terminal. The impedance comprises a resistive component (R) and an inductive component (X = Lω). The total impedance therefore depends on the frequency and is normally given for 0 Hz. This average value is given for the pole at its rated operational current. This is the average number of on-load operating cycles which the main pole contacts can perform without maintenance. The electrical durability depends on the utilisation category, the rated operational current and the rated operational voltage. This is the average number of no-load operating cycles (i.e. with zero current flow through the main poles) which the contactor can perform without mechanical failure. 0 () Conventional thermal current, in free air, conforming to IEC standards. () For a.c. applications, the breaking and making capacities are expressed by the rms value of the symmetrical component of the short-circuit current. Taking into account the maximum asymmetry which may exist in the circuit, the contacts therefore have to withstand a peak asymmetrical current which may be twice the rms symmetrical component. Note : these de nitions are extracted from standard IEC 09-.

70 General TeSys contactors Definitions and comments Contactor utilisation categories conforming to IEC 09- The standard utilisation categories de ne the current values which the contactor must be able to make or break. These values depend on: - the type of load being switched : squirrel cage or slip ring motor, resistors, - the conditions under which making or breaking takes place: motor stalled, starting or running, reversing, plugging. a.c. applications Category AC- This category applies to all types of a.c. load with a power factor equal to or greater than 0.9 (cos ϕ u 0.9). Application examples: heating, distribution. Category AC- Category AC- Category AC- d.c. applications Category DC- Category DC- Category DC- This category applies to starting, plugging and inching of slip ring motors. v On closing, the contactor makes the starting current, which is about. times the rated current of the motor. v On opening, it must break the starting current, at a voltage less than or equal to the mains supply voltage. This category applies to squirrel cage motors with breaking during normal running of the motor. v On closing, the contactor makes the starting current, which is about to times the rated current of the motor. v On opening, it breaks the rated current drawn by the motor; at this point, the voltage at the contactor terminals is about 0% of the mains supply voltage. Breaking is light. Application examples: all standard squirrel cage motors: lifts, escalators, conveyor belts, bucket elevators, compressors, pumps, mixers, air conditioning units, etc.... This category covers applications with plugging and inching of squirrel cage and slip ring motors. The contactor closes at a current peak which may be as high as or times the rated motor current. On opening it breaks this same current at a voltage which is higher, the lower the motor speed. This voltage can be the same as the mains voltage. Breaking is severe Application examples: printing machines, wire drawing machines, cranes and hoists, metallurgy industry. This category applies to all types of d.c. load with a time constant (L/R) of less than or equal to ms. This category applies to starting, counter-current braking and inching of shunt motors. Time constant y ms. v On closing, the contactor makes the starting current, which is about. times the rated motor current. v On opening, the contactor must be able to break. times the starting current at a voltage which is less than or equal to the mains voltage. The slower the motor speed, and therefore the lower its back e.m.f., the higher this voltage. Breaking is difficult. This category applies to starting, counter-current braking and inching of series wound motors. Time constant y. ms. On closing, the contactor makes a starting current peak which may be as high as. times the rated motor current. On opening, the contactor breaks this same current at a voltage which is higher, the lower the motor speed. This voltage can be the same as the mains voltage. Breaking is severe. Utilisation categories for auxiliary contacts & control relays conforming to IEC 09- a.c. applications Category AC- () This category applies to the switching of electromagnetic loads whose power drawn with the electromagnet closed is less than VA. Application example: switching the operating coil of contactors and relays. Category AC- () d.c. applications Category DC- () () Replaces category AC-. () Replaces category DC-. This category applies to the switching of electromagnetic loads whose power drawn with the electromagnet closed is more than VA. Application example: switching the operating coil of contactors.

85 Selection TeSys contactors For switching the primaries of -phase LV/LV transformers Operating conditions Contactor selection Contactor rating Maximum permissible current peak at switch-on Maximum operational power () Maximum ambient temperature: C. When a transformer is switched on, there is generally an initial current surge which reaches its peak value almost instantaneously and then decreases in a largely exponential manner to quickly reach its steady state value. The value of this current depends on: b the characteristics of the magnetic circuit and of the windings (cross sectional area of the core, rated inductance, number of turns, layout and size of the windings,...) b the performance of the magnetic laminations used, b the magnetic state of the circuit and the instantaneous value of the a.c. mains voltage at the moment of switch-on. The inrush current at the moment of switch-on can reach 0 to 0 times the rated current for the various kva power ratings in the tables below. This value is independent of the no-load or onload state of the transformer. The peak magnetising current of the transformer must be lower than the values given in the tables below.

86 Selection TeSys contactors For switching -phase capacitor banks used for power factor correction Standard contactors Capacitors, together with the circuits to which they are connected, form oscillatory circuits which can, at the moment of switch-on, give rise to high transient currents (> 0 In) at high frequencies ( to khz). As a general rule, the peak current on energisation is lower when: b the mains inductances are high, b the line transformer ratings are low, b the transformer short-circuit voltage is high, b the ratio between the sum of the ratings of the capacitors already switched into the circuit and that of the capacitor to be switched in is small (for multiple step capacitor banks). In accordance with standards IEC 000, NF C -00, VDE 00, the switching contactor must be able to withstand a continuous current of. times the rated current of the capacitor bank step being switched. The rated operational powers given in the tables below take this overload into account. Short-circuit protection is normally provided by gi type HPC fuses rated at. to In. Contactor applications Operating conditions Capacitors are directly switched. The values of peak current at switch-on must not exceed the values indicated opposite. An inductor may be inserted in each of the three phases supplying the capacitors to reduce the peak current, if necessary. Inductance values are determined according to the selected operating temperature. Power factor correction by a single-step capacitor bank The use of a choke inductor is unnecessary: the inductance of the mains supply is adequate to limit the peak to a value compatible with the contactor characteristics. Power factor correction by a multiple-step capacitor bank Select a special contactor as defi ned on page 9/.

87 Selection TeSys contactors For lighting circuits General The operating conditions of lighting circuits have the following characteristics: b continuous duty: the switching device can remain closed for several days or even months, b a dispersion factor of : all luminaires in the same group are switched on or off simultaneously, b a relatively high temperature around the device due to the enclosure, the presence of fuses, or an unventilated control panel location. This is why the operational current for lighting is lower than the value given for AC- duty. Protection The continuous duty current drawn by a lighting circuit is constant. In fact: b it is unlikely that the number of luminaires of an existing circuit will be modifi ed, b this type of circuit cannot create an overload of long duration. It is therefore only necessary to provide short-circuit protection. This can be provided by: b gg type fuses, or b modular circuit-breakers. Nevertheless, it is always possible and sometimes more economical (smaller cable size) to protect the circuit by a thermal overload relay and associated am type fuses. Distribution system Single-phase circuit, 0/0 V The tables on pages / to / are based on a single-phase 0/0 V circuit and can therefore be applied directly in this case. -phase circuit, 0/ V (with neutral) The total number of lamps (N) to be switched simultaneously is divided into three equal groups, each connected between one phase and neutral. The contactor can then be selected from the 0/0 V single-phase tables for a number of lamps equal to Nlamps phase circuit, 0/0 V The total number of lamps (N) to be switched simultaneously is divided into three equal groups, each connected between phases (L-L), (L-L), (L-L). The contactor can then be selected from the 0/0 V single-phase table for a number of lamps equal to N lamps. Contactor selection tables For the different types of lamps, the tables on pages / to / give the maximum number of lamps of unit power P (in Watts), which can be switched simultaneously for each size of contactor. They are based on: b a 0/0 V single-phase circuit, b an ambient temperature of C (), taking into account the operating conditions (see General paragraph). b an electrical life of more than 0 years (00 days operation per year). They take into account: b b b b the total current drawn (including ballast), transient phenomena which occur at switch-on, the starting currents and their duration, the circulation of any harmonics which may be present. Lamps with compensating capacitor C (µf) connected in parallel Parallel connected compensating capacitors C cause a current peak at the moment of switchon. To ensure that the value of this current peak remains compatible with the making characteristics of the contactors, the unit value of the capacitance must not exceed the following: Switching contactor rating Maximum unit value C (µf) of parallel connected compensating capacitor Switching contactor rating LP K09 K09 D09 D D D D D D0 D0 D D D9 D D0 F F F F0 F00 F00 F0 F00 Maximum unit value C (µf) of parallel connected compensating capacitor This value is independent of the number of lamps switched by the contactor.

93 Selection TeSys contactors For heating circuits Selection General A heating circuit is a power switching circuit supplying one or more resistive heating elements switched by a contactor. The same general rules apply as for motor circuits, except that heating circuits are not normally subjected to overload currents. It is therefore only necessary to provide short-circuit protection. Characteristics of heating elements The examples below are based on resistive heating elements used for industrial furnaces or for the heating of buildings (infra-red or resistive radiant type, convector heaters, closed loop heating circuits, etc.). The variation in resistance values between hot and cold states causes a current peak at switchon which never exceeds to times the rated operational current (In). This initial peak does not recur during normal operation where subsequent switching is thermostatically controlled. The rated power and current of a heater are given for the normal operating temperature. U KM Circuit controlled by poles of the contactor. Protection The steady state current drawn by a heating circuit is constant when the voltage is stable. In fact: b It is unlikely that the number of loads in an existing circuit will be modifi ed; b This type of circuit cannot create overloads. It is therefore only necessary to provide shortcircuit protection. This can be provided by: b gg type fuses, or modular circuit-breakers. b Nevertheless, it is always possible and sometimes more economical (smaller cable size) to protect the circuit by a thermal overload relay and associated am type fuses. Switching, control, protection A heating element or group of heating elements of a given power may be either single-phase or -phase and may be supplied from a 0/ V or a 00/0 V distribution system. Excluding a single-phase V system (which is no longer commonly used), the following types of circuit arrangement are possible: b b b Single-phase, -pole switching Single-phase, -pole switching -phase switching Component selection according to the power switched The combinations suggested below are based on an ambient temperature of C and for powers at the nominal voltage, but they also ensure switching in the event of prolonged overloads up to.0 Ue.

95 Recommended wiring scheme, operation, curves TeSys contactors For auto-transformer starting Applications Auto-transformer starting is suitable for starting all types of squirrel cage motors: with, or even 9 terminals according to North American technology. Starting is performed at reduced voltage and produces maximum torque at minimum line current. It allows the starting torque (C = f(u) ) to be adapted to the resistive torque of the driven machine by means of the or intermediate voltage take-off connections on the auto-transformer (0. and 0. Un or 0., 0. and 0. Un). In general, only one take-off connection is used. This type of starting is used for high power and/or high inertia machines. The motor is never disconnected from its power supply during starting (closed transition) and transient phenomena are eliminated.

The auto-transformer used generally has an air gap (adjusted or not) in order to obtain, during the second phase of starting, a series inductance whose value is compatible with correct starting.

97 Operation TeSys contactors For rotor circuits of slip-ring motors Applications These contactors are used to eliminate starting resistance in the rotor circuit of slipring motors. The most common application is for starters without inching and without rotor speed adjustment: pumps, fans, conveyors, compressors,... In the case of control by means of a manually operated master controller, the use of contactors with magnetic blow-out is recommended. Please consult your Regional Sales Office. For hoisting applications, contactor selection must take into account the type of motor duty, the operating rate, the rotor voltage and current, the type of connection, the ambient temperature, etc. Please consult your Regional Sales Offi ce. Operation The rotor circuit contactors are interlocked with the stator contactor and therefore do not open until after the stator contactor has opened, when the rotor voltage has disappeared, or virtually disappeared. They make the current corresponding to the normal starting peak (. to. times the rated rotor current) and open the circuit under no-load. Making and breaking are easy.

99 General TeSys contactors Long distance remote control Voltage drop caused by the inrush current When the operating coil of a contactor is energised, the inrush current produces a voltage drop in the control circuit cable caused by the resistance of the conductors, which can adversely affect closing of the contactor. An excessive voltage drop in the control supply cables (both a.c. and d.c.) can lead to non closure of the contactor poles or even destruction of the coil due to overheating. This phenomenon is aggravated by: b b b a long line, a low control circuit voltage, a cable with a small c.s.a., a high inrush power drawn by the coil. b The maximum length of cable, depending on the control voltage, the inrush power and the conductor c.s.a., is indicated in the graphs below. Remedial action To reduce the voltage drop at switch-on: b b increase the conductor c.s.a., use a higher control circuit voltage, use an intermediate control relay. b Selection of conductor c.s.a. These graphs are for a maximum line voltage drop of %. They give a direct indication of the copper conductor c.s.a. to be used for the control cable, depending on its length, the inrush power drawn by the contactor coil and the control circuit voltage (see example page 9).

On the right-hand graph on the page opposite, point Y is at the intersection of the vertical line corresponding to 0 m and the horizontal line passing through point X. Use the conductor c.s.a. indicated by the curve which passes through point Y, i.e.:. mm. If point Y lies between two c.s.a. curves, choose the larger of the c.s.a. values. Calculating the maximum cable length The maximum permissible length for acceptable line voltage drop is calculated by the formula: U L =.s.k SA where: L : distance between the contactor and the control device in m (length of the cable), U : supply voltage in V, SA : apparent inrush power drawn by the coil in VA, s : conductor c.s.a. in mm, K : factor given in the table below. a.c. supply SA in VA K.... d.c. supply Irrespective of the apparent inrush power SA, expressed in W K =. 9

101 General (continued) TeSys contactors Long distance remote control Residual current in the coil due to cable capacitance When the control contact of a contactor is opened, the control cable capacitance is effectively in series with the coil of the electromagnet. This capacitance can cause a residual current to be maintained in the coil, with the risk that the contactor will remain closed. This only applies to contactors operating on an a.c. supply. This phenomenon is aggravated by: b a long line length between the coil control contact and the contactor, or between the coil control contact and the power supply, b a high control circuit voltage, b a low coil consumption, sealed, b a low value of contactor drop-out voltage. The maximum control cable length, according to the contactor coil supply voltage, is indicated in the graph on the page opposite. Remedial action Various solutions can be adopted to avoid the risk of the contactor remaining closed due to cable capacitance: b use a d.c. control voltage, or, b add a rectifi er, connected as shown in the scheme below, but retaining an a.c. operating coil: in this way, rectifi ed a.c. current flows in the control cable. When calculating the maximum cable length, take the resistance of the conductors into account.. L + A Supply 0/0 Hz A b Connect a resistor in parallel with the contactor coil (). Value of the resistance : R Ω = 0 C (μf) (C capacitance of the control cable)-en_ver..indd Power to be dissipated : PW = U R () To avoid increasing the voltage drop due to inrush current, this resistor must be brought into operation after the contactor has closed by using an N/O contact. 9

On the left-hand graph, point A is at the intersection of the vertical line for VA with the a 0 V voltage curve. 9 On the right-hand graph, point B is at the intersection of the horizontal line with the -wire control curve. The maximum cable length is therefore 00 m. In the same example, with a 00 m cable, the point lies in the risk zone. A resistor must therefore be connected in parallel with the contactor coil. 0 Value of this resistance : R = = =. Ω 0. C Power to be dissipated : U P = = (0) = W R 00 Alternative solution: use a d.c. control supply. Calculating the cable length The maximum permitted length of control cable to avoid the effects of capacitance is calculated using the formula: L =.
