    Tips: What is a DC contactor?

    DC contactor is mainly used for remotely connecting and disconnecting the DC circuit, as well as frequently starting, stopping, reversing and plug braking the DC motors. It's also widely used for connecting and disconnecting the lifting electromagnet, solenoid valve, clutch's magnetic coils. DC contactor has two structure of stereoscopic arrangement and plane arrangement, some products are derived on the basis of AC contactor. Therefore, structure and working principle of the DC contactor are basically the same as that of AC contactor, which mainly consists of three parts, electromagnetic mechanism, contact system and arc-extinguishing equipment.

    Nice contactor, used it as a replacement in my 1997 Ford F-250
    Really nice contactor! I used this single pole contactor as a replacement glow plug relay (GPR) in my 1997 Ford F-250 (97 F250), it works better than the original one. Started in cold weather without any problem.

    12V dc contactor worked great
    Worked great. I installed the 12V dc contactor in a 2000 F350 7.3 diesel for the glow plug relay. Truck starts now no matter the outside temperature.
