STANDARD DC182
MOTOR REVERSING
The DC182 contactor has been designed for direct current loads, particularly motors as used on electric vehicles such as industrial trucks and airport tractors.
The DC182 has double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity. The DC182 main contact circuit, designed for motor reversing, is such that it has a built in failsafe, so that if both coils are energised simultaneously the contact arrangement is open circuits. The DC182 is a monoblock construction, resulting in a neat compact design which is compatible with modern electronic control systems. Main terminals can be configured in a variety of ways in order to suit the application.
