Is the undervoltage release (UVR or MN) for the Powerpact M, P, and R frame breakers "kiss-free?"


28 September 2021

If the UVR is not energized, will the main contacts touch when an attempt is made to close the breaker?

Product Line:
Circuit Breakers

They are kiss-free. If the undervoltage trip is not energized, it is impossible to close the circuit breaker either manually or electrically. An attempt to close the circuit breaker produces no movement of the main contacts.
