Series CA7 Contactors

1 Series 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 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 horsepower range (up to 6/575V). Six of the contactors are only 5mm wide, an extremely small footprint for such rugged performance. number of design features account for this efficiency, including high contact pressure and bouncefree contacts, allowing the devices to handle the high starting currents typical of modern motors. Type and Type Coordination Whether you re designing motor circuits for use in North merica, Europe or any other part of the world, all contactors have been designed and tested with respect to Type and Type short circuit coordination. Find out more in the Technical Information section in this chapter. dvanced safety and reliability features The entire 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 (.mm) to ensure that the auxiliary contacts do not change state when coil power is removed and the device tries to open. This is a requirement in safety circuits per IEC Reliability is further assured by crossstamped auxiliary contacts, which provide multi-point reliability in low current, low voltage applications. Three types of DC coils available -9C through C contactors are available with true DC or Electronic V DC coils that dramatically decrease wattage consumption during pull-in. This allows the use of smaller power supplies. The entire line is also available with a two winding DC coil that reduces the size of the contactor, as well as the hold-in values. Two winding coils include built-in coil suppression and an internal contact that bypasses the pull-in coil to the hold-in coil. 5mm ( / ) 9 6 5mm ( / ) 7 5mm ( /8 ) 7mm ( /6 ) SSN9 8

2 Modular accessories are common to all devices Reversible coil provides total flexibility ll accessories are interchangeable among all 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. 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 contactors - 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 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 Capacitor contactors 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. SSN9 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, and 6. CNX Special Purpose CQ7 Capacitor Switching Sprecher + Schuh s expanded line includes contactors designed and labeled for specific industrial applications NEM Labeled CN7 contactors are UL Listed and rated in accordance with the requirements of NEM standards publication ICS-. These contactors are NEM compliant and are labeled accordingly. Special purpose contactors CNX contactors are standard contactors that have been tested, approved and labeled by UL for heating ventilation and air conditioning (HVC) applications. 9
