The undervoltage release is an electronic module used to open the circuit breaker when the monitored voltage drops below 35-60PERC 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 60-85PERC of its rated voltage). An undervoltage release trip operation is produced by the MicroVersaTrip½ 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 MicroVer saTri p½ 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. Field installable. 0ACR Frame Rating Amps 2500

Control wiring is connected through drawout secondary disconnects in the "TEST" and "CONNECTED" positions only. Up to 72 control circuits are possible through 36 position plug-style secondary disconnects mounted to each side of drawout breakers. One substructure disconnect (SPDOSD36S) must be ordered for each breaker when accessories or communications are used. When auxiliary switches are used along with any other electrical accessory or communications, two disconnects must be ordered. SD36S

Auxiliary switches provide remote indication of whether the circuit breaker main contacts are opened or closed via open or closed SPDT elements. AB8DR

The electrical operator mounts inside the front cover of the manually operated breaker. The accessory can be added to any Power Break II breaker in the factory or the field to provide electrical spring charging and charge indication. For remote closing, the remote close solenoid must be priced and ordered separately. All breakers are prewired to dedicated secondary terminals for easy field installation. When electrical operation is used, either a shunt trip or an undervoltage release accessory is required for remote opening. These accessories must be ordered and priced separately. 024R Frame Rating Amps 2500
