DC66P Monoblock, Single Pole Double Throw for Motor Reversing0 pages
DC66P Monoblock, Single Pole Double Throw for Motor Reversing
(Part of the SW60 Series)
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.
Interrupted
Uninterrupted
Thermal Current Rating (Ith)
•t
Interrupted current - opening and closing on load
with frequent switching (results in increased contact
resistance).
•t
Application
Uninterrupted current - no or infrequent load switching
requirements (maintains a lower contact resistance).

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.
