ELECTRICAL MOTOR CONTACTORS
Series CA6 Contactors up to 700 HP
The modern contactor for demanding applications
Sprecher + Schuh’s CA6 contactor line combines the simple function of our popular CA7 contactor 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.
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.
