MicroVersaTrip PM™ Metering and Relaying (cont.)
Rating Plugs
Interchangeable rating plugs are used in all of the
MicroVersaTrip Plus™ and MicroVersaTrip PM™ trip
units across the entire WavePro™ breaker product line.
Rating plugs are the key devices that establish the current
rating of the breaker. They provide an essential scaling func-
tion for the unit’s microprocessor and ensure maximum
accuracy. They also provide a jack for connection to an
external battery pack or trip unit test kit.
Rating plugs have
rejection features
that allow them to
be inserted only with
breakers containing
the correct current
sensors. Rating
plugs for the
MicroVersaTrip Plus
and MicroVersaTrip
PM trip units cannot
be used with Spectra RMS™ molded case circuit breakers,
but are compatible with Power Break
®
, Power Break
®
II,
and type AKR breakers with MicroVersaTrip Plus and
MicroVersaTrip PM trip units. See Table 26.1 for
available ratings.

Current Sensors
Toroidally wound current sensors are furnished for all
major protective functions, and for use with MicroVersaTrip
Plus and PM metering functions. Current sensors are
factory installed. There are nine current sensor ratings
for the WavePro breaker line through 5000 amps. See Table
26.1 for current ratings. Rating plugs must be coordinated
with the current sensor rating (CT) listed on the face of
the rating plug.

Bell Alarm
Activation of the Bell Alarm is controlled by the trip unit.
All protective function trips initiated by the trip unit will
cause the bell alarm (if so equipped) to operate. Reset of
the bell alarm contacts and the mechanical lockout (if
provided) is by way of the reset button on the breaker
escutcheon.
