The modern contactor for demanding applications

Sprecher + Schuh’s CA9 contactor line combines the simple function of our popular CA7 series with the rugged performance demanded in this wide horsepower range. CA9 contactors offer a smaller footprint than traditional contactors in this size class.

A broad selection for middle horsepower applications

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.

Built in Safety Features

CA9 arc chambers are completely enclosed (without arc exhaust vents), offering the best protection against hot arcing gases.

Rugged and reliable

CA9 contactors conform to UL508, IEC 60947 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.

Arc quenching extends contact life

All CA9 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 CA9 contactor are advanced engineering solutions that offer convenience and savings. The entire line is equipped with an electronically controlled coil that reduces pick-up currents by 80% on average. Holding current is also reduced.
