Contactors
Series CA6 Contactors up to 700 HP
Meeting the demands of Middle Horsepower Applications
Sprecher + Schuh's CA6 contactor line combines the simple function of the popular CA7 series with the rugged performance demanded in this middle horsepower range. On average these contactors are 50% smaller than traditional contactors in this size class. CA6 contactors range from 75 to 700 HP (@ 575V). Offering includes reversing applications, switching heaters or transformers and including elevator duty, and NEMA Sized ratings. Various features include electronic coils and electronic interface with rugged performance of 1 million operations or more.
>A Broad Selection For Middle Horsepower Applications
The CA6 contactor family consists of a wide range of amperages in several frame sizes. This line is ideally suited for demanding applications such as steel mills, rock quarries, mines or for any middle horsepower application where a sturdy, durable contactor is needed.
>Built In Safety Features
The CA6 contactor series has a built in safety feature that disengages the coil contacts and locks them in place when the contactor cover is opened for inspection. Conversely, when the contactor is energized, the cover cannot be removed. This feature ensures the current carrying components are power free during maintenance or replacement operations. Contact replacements can be installed quickly and safely, extending the life of the contactor.
>Rugged And Reliable
CA6 contactors conform to UL508, as well as IEC 947 and can be operated at rated voltages up to 600V (UL) and 1000V (IEC). High thermal and switching capacities guarantee reliable operation and long life. CA6 contactors are listed in CSA Certified Elevator Equipment for heavy duty use in elevators, refrigerators and heating installations in Canada.
>Arc Quenching Extends Contact Life
All CA6 contactors are designed with sophisticated arc quenching techniques that extinguish damaging breaking arcs quickly.
>Electronic Coils Offer Many Advantages
Behind the attractive outward appearance of the CA6 contactor are advanced engineering solutions that offer convenience and savings. The CA6-115-EI through 420-EI incorporate an electronically controlled coil that reduces pick-up currents by 60% on average. Holding current is also reduced. The CA6 electronic coil also permits direct connection to a PLC.

Series CA7 Contactors up to 75 HP
General Purpose And Special Purpose Starting At Just 45mm Wide
The CA7 Series of general and special purpose contactors represents the most modern and flexible power contactor available today. A wide selection of contactors in several frame sizes covers the entire CA7 horsepower range (up to 75HP @ 460/575V). Offering includes reversing applications, lighting applications, switching heaters or transformers, including elevator duty, NEMA ratings and HVAC ratings. Various features include DC electronic coils, dual power terminals, mechanically linked contacts (forced guided contacts), and electronic interface. Many of the contactors are only 45mm wide, an extremely small footprint for such rugged performance of 1 million operations or more.

>Same Small Size For Most DC Applications The CA7-9 to 55A contactor sizes include an Electronic DC Coil option. The Electronic DC contactor design is the same size as the AC contactors, providing a compact unit for DC applications. Very low inrush and low power consumption result in a smaller power supply and smaller panel size. |
>Type 1 And Type 2 Coordination
Whether you are designing motor circuits for use in North America, Europe or any other part of the world, all CA7 contactors have been designed and tested with respect to Type 1 and Type 2 short circuit coordination.
>Advanced Safety And Reliability Features
The entire CA7 contactor line features mechanically linked contacts, such that if a main power pole welds, adequate clearances exist (greater than or equal to 0.3mm) 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.
>Modular Accessories Are Common To All Devices
All accessories are interchangeable among all CA7 contactors and CS7 control relays. This minimizes inventory requirements and maximizes flexibility.
>Reversible Coil Provides Total Flexibility
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. CA7 contactors can either be ordered with the coil reversed or may be easily reversed in the field.
>Dual Power Terminals Speed Wiring
CA7-30 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 two-speed applications. Simplified wiring means less labor and less cost.
Series CA9 Contactors up to 1150 HP
The Modern Contactor For Demanding Applications
The CA9 series of large amperage contactor are the modern (smaller footprint) contactor for demanding applications. The CA9 line combines the simple function of our popular CA7 series with the rugged performance demanded in this wide horsepower range. The CA9 range consists of sixteen contactors in six frame sizes covering motors from 75 to 900HP at 460V and from 100 to 1150HP at 575V. This line is ideally suited for demanding applications such as steel mills, rock quarries, mines or for any middle horsepower application where a sturdy, durable contactor is needed. The entire line is equipped with an electronically controlled coil that reduces pick-up currents by 80% on average. Holding current is also reduced.
