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:

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