Motor Reversing


The DC66P is a compact contactor following the established design of our mono block contactors, configured specifically for motor reversing.  Suitable for Direct Current loads and compatible with modern electronic control systems, the DC66P is sealed to IP66 and is ideal for use in applications such as battery powered winches, vehicle mounted cranes and small electric vehicles.  Devised for both interrupted and uninterrupted loads, the DC66P is suitable for switching Resistive, Capacitive and Inductive loads.

The main contact circuit has a built in fail safe, so that if both coils are energised simultaneously the contact arrangement is open circuit.  The DC66P has double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity.  The DC66P has M6 main stud terminals and coil connections are by means of 6.3mm spades.
