1 C7 Series C7 Rugged, space saving and modular Sprecher + Schuh s newest contactor for applications up to 6HP Over years of design experience has produced Sprecher + Schuh s seventh generation contactor line. The C7 represents the most modern and flexible power contactor available today, meeting the highest industrial application requirements. Big performance in a small package wide selection of ten contactors in four frame sizes covers the entire C7 horsepower range (up to 46/575V). Six of the contactors are only 45mm wide, an extremely small footprint for such rugged performance. number of design features account for this efficiency, including high contact pressure and bounce-free contacts, allowing the devices to handle the high starting currents typical of modern motors. Type and Type 2 Coordination Whether you re designing motor circuits for use in North merica, Europe or any other part of the world, all C7 contactors have been designed and tested with respect to Type and Type 2 short circuit coordination. Find out more in the C7 Technical Information section in this chapter. dvanced safety and reliability features The entire C7 line features mechanically linked contacts, sometimes referred to as positively guided contacts or force guided contacts. If a main power pole welds, adequate clearances exist (.3mm) to ensure that the auxiliary contacts do not change state w hen coil power is removed and the device tries to open. This is a requirement in safety circuits per IEC Reliability is further assured by cross-stamped auxiliary contacts, which provide multi-point reliability in low current, low voltage applications. Two types of DC coils available C7-9C through 43C contactors are available with true DC coils that dramatically decrease wattage consumption during pull-in. This allows the use of smaller power supplies. The entire C7 line is also available with a two winding DC coil that reduces the size of the contactor, as well as the holdin values. Two winding coils include built-in coil suppression and an internal contact that bypasses the pull-in coil to the hold-in coil. 45mm ( 3/4 ) mm ( 3/4 ) mm ( 2 /8 ) 43 72mm ( 2 3/6 ) SSCDN85E 8

2 Modular accessories are common to all devices Reversible coil provides total flexibility ll accessories are interchangeable among all C7 contactors and CS7 control relays. This minimizes inventory requirements and maximizes flexibility. Top and side mount auxiliary contacts are available depending on your application. mechanical interlock with two built-in NC auxiliaries also provides electrical interlocking if desired. Pneumatic and electronic timers, surge suppressors and electronic interface modules provide solutions for even the most complex applications. When shipped, both coil connections are normally located at the top of the contactor in preparation for mounting an overload relay at the bottom. For multi-starter panels, however, the coil can be reversed, which provides space to close-couple a KT7 Motor Circuit Controller on the top of the contactor. C7 contactors can either be ordered with the coil reversed or may be easily reversed in the field. Dual power terminals speed wiring Top mounted coil Bottom mounted coil Reversible coils are standard on all C7 contactors C7 C7-3 through 85 contactors are designed with two power terminals for all three poles. This simplifies power wiring of interconnected contactors in reversing, reduced voltage and twospeed applications. Preformed power wiring connectors are also available for virtually instantaneous wiring in these labor intensive applications. Simplified wiring means less labor and less cost. Two power terminals on each pole Dual power terminals assure hassle-free wiring in complex control schemes Special use contactors for specialized applications The C7 line has been expanded to include a number of contactors designed and labeled for specific industrial applications. In all cases, these devices are UL and CS approved for these specialized uses. CL7 Lighting Contactor CQ7 contactors manage the peak inrush common with capacitor switching by incorporating a built-in set of resistors and early-make contacts, wired in parallel with the power contacts, to pre-charge the capacitors. Selection is based on applied KVR. NEM Labeled SSCDN85E Lighting contactors The CL7 contactor can be used to control a wide variety of lighting loads. These contactors are well suited to handle the high inrush currents typical of this application as well as other nonmotor (resistive) loads. Both mechanically held and electrically held models are available for lighting load applications up to 2, 3 and 6. Capacitor contactors CNX Special Purpose Contactor CQ7 Capacitor Switching Contactor Sprecher + Schuh s expanded C7 line includes contactors designed and labeled for specific industrial applications CN7 contactors are UL Listed and rated in accordance with the requirements of NEM standards publication ICS-2. These contactors are NEM compliant and are labeled accordingly. Special purpose contactors CNX contactors are standard C7 contactors that have been tested, approved and labeled by UL for heating ventilation and air conditioning (HVC) applications. 9

17 Technical Information Capacitor Switching - Series CQ7 CQ7 Theory of Operation Single capacitor switching is often used in power factor correction on individual loads. Inrush current at the point of becoming energized can peak to 3 times normal current (see Figure ) depending on impedance of cables and transformers. Capacitor bank switching is often used in power factor correction on multiple loads. Inrush current at the point of becoming energized can peak to 2 times normal current (see Figure 2) because each capacitor in the bank acts as an additional power source and therefore feeds additional current to the circuit. Complications of capacitor switching with standard contactors can include nuisance tripping of the short circuit protective device, welding of main contacts, and stress on components resulting in reduced life of capacitors. Managing the peak inrush common with capacitor switching can involve complicated dimensioning in the form of over sizing standard contactors combined with adding coils of wire. CQ7 contactors offer a simple alternative solution by combining a built-in set of resistors and earlymake contacts, wired in parallel with the power contacts, to pre-charge the capacitors. The increased impedance of the CQ7 resistors is only present in the circuit during inrush. This circuitry is housed in a front mount add-on deck similar to a four pole auxiliary block, which results in a compact design and ease of selection based on applied KVR. CQ7 is available with C or DC coils and with NO & NC (see Figure 3) or 2 NO auxiliary contacts (see Figure 4). CQ7 contactors only show UL/CS pproved capacitor ratings on the nameplate and should not be used for switching motors.

22 Series CL7 Lighting Compact contactors for North merican lighting applications Sprecher + Schuh C7 and C6 contactors can be used to control a wide variety of lighting loads. These contactors are well suited to handle the high inrush currents typical of this application as well as other non-motor (resistive) loads. Lamps can basically be divided into three categories: Tungsten Filament Lamps - General purpose incandescent - Special purpose incandescent - Infrared - Sodium Iodine Discharge Lamps (with Ballast) - Fluorescent lamps - Mercury vapor - High/low pressure sodium - Quartz - Halogen metal-vapor Mixed Light Lamps able for use where the control signal is activated by a timer or other maintained electrical signal. The coil is energized as long as the contactor is closed. This design is well suited for applications where lights are operated frequently or where the control panel is in a remote location. CL7 In application The tungsten filaments of incandescent lamps have a very low ohmic resistance when cold. s a result, the closing current is very high but also very short. The closing current of discharge lamps (lighting with ballast) is highly inductive (due to series-connected transformers or chokes), and its duration depends on the lamp type. In general, North mericans refer to Lighting Contactor ratings in amperes without distinction between incandescent or ballast type of load. The lighting contactor selection table provided on the following page is for North merican use, so ratings are selected for mixed lamp loads which account for the higher incandescent inrush. Mechanically held contactors Mechanically held contactors are available for applications where quiet operation or critical lighting is required, i.e., institutions, hospitals and residential/commercial areas. fter the contactor closes, the voltage is disconnected from the operating coil and the contactor is held closed by the mechanical latch. Built-in clearing interlocks allow control from either a momentary or maintained pilot device for the separate pull-in and release functions. Europeans usually separate the values for incandescent from discharge (ballast) lighting. Both values are provided in the technical section of our general catalog and may be more appropriate for those applying by CE standards.
