The modern contactor for demanding applications from 75 to 600HP (@460V) - 100 to 700HP (@ 575V)
Sprecher + Schuh’s CA6 contactor linecombines the simple function of ourpopular CA7 series with the ruggedperformance demanded in this middlehorsepower range. On average thesecontactors are 50% smaller than traditionalcontactors in this size class.
A broad selection for middle horsepower applications
The CA6 range consists of nine contactors in three frame sizes covering motors from 75 to 600HP at 460V and from 100 to 700HP 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.
Rugged and reliable
CA6 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. 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. This is accomplished by guiding the arc away from the contacts and into “arc chambers” which are built-in to every CA6 cover.
CA6 arc chambers are completely enclosed (without arc exhaust vents), offering the best protection against hot arcing gases. A large safety distance in front of the contactor is unnecessary. CA6 contactors are also designed so that operation is impossible if the arc chambers are removed. Conversely, once the contactor is energized, the arc chambers cannot be removed. When used with terminal covers or HB Touch-Safe Lugs, CA6 contactors meet international standards for touch-safe design.
