On average these Contactors are 50% smaller than tradi-tional Contactors in this size broad selection for middle horsepower applicationsThe 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 and reliableCA6 Contactors conform to UL508, IEC 60947 and can be operated at rated voltages up to 600V (UL) and 1000V (IEC).

2 High thermal and switching capacities guarantee reli-able operation and long life. CA6 Contactors are listed in CSA Certified Elevator Equipment for heavy duty use in elevators, refrigerators and heating installations in quenching extends contact lifeAll CA6 Contactors are designed with sophisticated arc quenching techniques that extinguish damaging breaking arcs quickly. This is accomplished by guid-ing the arc away from the contacts and into arc chambers which are built-in to every CA6 firstCA6 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 used with terminal covers or HB Touch-Safe Lugs, CA6 Contactors meet international standards for touch-safe ( 4 3/4 ) 115A155mm( 6 3/32 )210A250A300A420A120mm( 4 3/4 )

The entire line can be equipped with an electronically controlled coil that reduces pick-up currents by 60% on average. Holding current is also advantages of the CA6 electronic coil include: Direct connection to a PLC Overvoltage protection and suppres-sion circuits (eliminating interfer-ence from the coil) are standardThe entire CA6 line is modularly de-signed for easy inspection, coil change and contact replacement.

4 Maintenance can be performed from the front so that mounting requires no additional space. Even with the installation of mechanical interlocks and auxiliary contact blocks, the units can be flush mounted side by side, saving panel CA6-115-EI Contactor2 CA6-140-EI Contactor3 Main Terminal Set4 Lug set5 Mechanical Interlock6 Aux.

5 The coil is set in the E mode from the factory, offering all of the functions and advantages of an electronic coil with the exception of electronic interface. An orange jumper located on the bottom of the contactor can be quickly changed if interface from a PLC is desired.
