    50A DC Reversing Contactor Details

    Tips: Short circuit of the contactor, how to solve?

    Possible causes of the fault:

    • The contactor works in the environment of damp, dust, steam, or corrosive gases.
    • The arc chute damages or falls, load short leads to the contact short of the contactor.
    • Incorrect operation of the positive and reverse contactor, as well as unreliable interlocking, make two contactors to pull in at a same time when reversing.

    Maintenance method:

    1. Improve the working environment and keep clean.
    2. Match an arc-extinguishing equipment again.
    3. Handle the load short failure.
    4. Recheck the contactor's interlocking circuit, change the operation mode.
