The Mechanical Operations Counter is mounted behind the front cover of the breaker. It is viewable through a rectangular knockout window opening in the breaker cover. It is a five digit, non-resettable counter which is actuated each time the breaker is opened by any means.

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. 125R Frame Rating Amps 4000

This accessory provides an electrically operated solenoid, which, when energized, closes the breaker. It is suitable for control interlock schemes in which manual closing capability would not be convenient or desirable. The breaker is provided with a manual close button which can be replaced by the Hidden "ON" Button accessory and/or sealed using the Limited Access Pushbutton Cover accessory. The remote closing accessory is continuously rated and has an anti-pump feature which prevents a motor operated breaker from repeatedly closing into a fault. Closing control voltage must be removed and re-applied for each breaker closure. 024R Frame Rating Amps 800

Auxiliary switches provide remote indication of whether the circuit breaker main contacts are opened or closed via open or closed SPDT elements. 0AB4R

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. 4DCR Frame Rating Amps 1600

Substructures are available for both standard and Hi-Break Power Break II breakers. Holes are provided for bolting on a shelf or supports. Holes are provided in the primary stabs for bolting to busbars or terminal lugs. Substructure secondary disconnects are ordered and priced separately. OS20 Frame Rating Amps 800

This field installable rail kit may be used to shorten the two standard OEM substructures by 3 1/2 inches.
