Issue:
Does a UV trip or UVR undervoltage release sense phase loss?

Product Line:
Circuit Breakers

Environment:
Circuit breakers that have a UVR undervoltage trip

Resolution:
The UVR will sense phase loss only on the phase(s) its control power is taken from. The UVR should not be used in place of a phase-failure. See the latest Digest for phase-failure relay information.
