Tips: Troubleshooting of VCB

In the troubleshooting process, two types of problems are mainly detected, here is the solution.

Closing Problem. In the mechanism or control circuit, if a part cannot be closed, it needs to be replaced. If there is a closing sound, but the breaker is still open, then check the alignment or go for replacement. If there is no loss of signal when closing, then realignment or replacement is required.

Tripping Operation. If the operating mechanism or control circuit parts cannot trip, go for replacement. If there is a tripping sound, but the circuit breaker is still closed, it needs to be replaced. Similarly, replacement is the solution for a trip without tripping signal too.
