Accessories - Stationary and

Drawout Breakers

The complete line of Power Break® I I breaker accessories
may be either factory installed or field installed 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 drop in from the front of all
breakers. One of each of the above accessory modules can
be installed, and requires no field internal wiring or breaker

disassembly. The accessory modules are i nterchangeable
across all frame sizes.

Auxiliary switch modules are available in g roups of 4, 8, o r

1 2 , NO/NC single-pole, double-throw (SPOT) switches. Their
installation simply involves removal of breaker cover, instal
lation of the switch module, routing of wiring and installation

of the pre-wired terminal block and re-installati o n of the
cover. Auxiliary switches a re also interchangeable across all

Power Break I I breaker frames.

Test Kit

The test kit, catalog number TVRMS2 is a portable, battery

powered, test kit which provides for trip unit health checks
and functional trip and no-trip test . It also provides defeat
of the ground-fault function and can be used in conjunction

with h igh-current test equipment. The test kit can be used to

p24V 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

trip units.

Electrical Operator

The electrical operator mounts i nside the front cover of the

man ually operated b reaker. This 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 shunt trip or an undervoltage release accessory

are required for remote closing and opening.

Power Break I I breaker electrical operator

The electrical operator can be wired to charge automatically
following a CLOSE operation, or to charge on command. A

remote charge indicator switch is integral 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 separate handles a re requ i red.

However. if the charge cycle is begun manually, it m ust be
competed manually. Any electrically operated breaker can
be operated manually.

The control power required for each m otor operator may be

determined from Table 25.2. If several motor operators ore

fed from the same source, it should be sized to accommo
date all operators simultaneously,

especially

they a re wired

for automatic

charge.

The voltage drop in sou rce supply from no-load to motor
full-load current should not exceed 7% of nominal voltage.
Acceptable de power supplies ore: three-phose, full-wave
rectified ac; battery; de generator or a ny other de source with
a peak-to-peak ripple voltage of not more than 15% at rated
full-load current . Operating range of electrical o perator: 90%
- 110% of nominal rating. See wiring diagram on page 26.
