Accessories - Stationary and
Drawout Breakers
The complete line of Power B reak® I I breaker accessories
may be either factory insta lled or field insta lled to meet user
needs. The electronic shunt trip (with or without lockout), the
bell alarm, the bell alarm with mechanical lockout, and the
undervoltage release modules d rop in from the front of all
breakers. One of each of the a bove a ccessory modules can
be installed, and req uires no field internal wiring or breaker
disassembly. The accessory modules a re i nterchangeable
across all frame sizes.
Auxiliary switch modules a re ava i lable in g roups of 4, 8, o r
1 2 , NO/NC sing le-pole, double-th row (SPOT) switches. Their
instal lation sim ply involves removal of breaker cover, insta l­
lation of the switch module, routing of wiring and installation
of the pre-wired terminal block and re-instal lati o n of the
cover. Auxiliary switches a re a lso interchangeable across a l l
Power Break I I breaker frames.

Test Kit

The test kit , cata log num ber TVR MS2 is a portable, battery­
powered, test kit which p rovides for trip unit health checks
and functional trip and no-trip test . It a lso provides defeat
of the g round-fa ult function and can be used in conjunction
with h igh-current test equipment. The test kit can be used to
p rovide +24V power to the trip unit for cold set-u p and view
of trip targets. This test kit is for use with Power+™, MicroVer­
saTrip Plus™ and MicroVersaTrip PM

Electrical Operator

The electrical operator mounts i nside the front cover of the
man u ally operated b reaker. Th i s accessory can be added
to any Power Break II breaker in the factory or the field t
provide electrical spring charging. All breakers a re pre-w1red
to dedicated secondary terminals for easy field installation.
When electrical operation is used, a remote close solenoid
and either a s hunt trip or an undervoltage release accessory
a re req u i red for remote closing and opening.

The electrical operator can be wired to charge automatically
fol lowing a CLOSE operation, or to charge on command. A
remote cha rge indicator switch is i ntegral to the electrical
operator. If control power is lost during the charging cycle,
spring charging con be completed manually using the pump
handle - no special tools or se pa rate handles a re requ i red.
However. if the cha rge cycle is begun manually, it m ust be
com peted manually. Any electrically operated breaker can
be operated manually.
The control power req uired for each m otor operator may be
determined from Table 25.2. If several motor operators o re
