The undervoltage release is an electronic module used to open the circuit breaker when the monitored voltage drops below 35 to 60% of its rated value. The undervoltage release resets when the monitored voltage is re-established allowing the circuit breaker to reclose (the sealing voltage of the UVR is 60 to 85% of its rated voltage). An undervoltage release trip operation is produced by the MicroVersaTrip Plus™ unit in response to a signal from the undervoltage release module. This allows the trip unit to record, display, distinguish an d comm un icate (in MicroVersaTrip PM™ trip units) that the breaker opening event was due to undervoltage release. Operation of the undervoltage release module will prevent breaker contact closure, i.e. kiss-free operation. When energized, the undervoltage release supplies 24 VDC power to the trip unit to power the display.
