DC88P-1000 Type Monoblock, Single Pole Double Throw
for Motor Reversing - IP66 (Part of the SW80 Series)

100A

The DC88P-1000 motor reversing type of contactors has been designed for direct current loads, particularly
motors as used on electric vehicles such as industrial trucks. The DC88P-1000 Type is a monoblock
construction, resulting in a neat compact design which is compatible with modern electronic control systems.
Developed for both interrupted and uninterrupted loads, the DC88P-1000 Type is suitable for switching
Resistive, Capacitive and Inductive loads. The DC88P-1000 Type is sealed to IP66 thus offering greater
protection against adverse environments such as water or dust.
•t

Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance).

•t

Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).

The main contact circuit, designed for motor reversing, has a built in failsafe, so that if both coils are energised
simultaneously the contact arrangement is open circuit. The DC88P-1000 Type has double breaking main contacts with
silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity. The DC88P-1000 Type
M8 main stud terminals can be configured in a variety of ways
