Power Break® II Circuit Breaker Accessories
Undervoltage Release
Introduction
The Undervoltage Release (UVR) accessory, shown in Figure
1, can be installed in 800–4000 ampere frame Power Break II
circuit breakers. This accessory trips the circuit breaker
when the input control voltage drops to 35–60% of its rated
value and prevents an open breaker from closing until the
input control voltage is greater than 80% of the rated value.
In addition to providing a trip signal to the breaker, the UVR
accessory can be set up to interact with other Power Break II
accessories, when used with a MicroVersaTrip Plus or
MicroVersaTrip PM Trip Unit. DIP switches on the rear of
the breaker Trip Unit can configure the UVR accessory to
activate a Bell Alarm–Alarm Only accessory or a Bell Alarm
with Lockout accessory when a UVR trip occurs. The
Accessory Configuration section below describes how this
can be done. If the breaker is equipped with a Power+ Trip
Unit, it is configured so that only protection trips will
activate a Bell Alarm–Alarm Only or Bell Alarm with Lockout.
The catalog numbers for the UVR for various voltage applica-
tions are listed in Table 1.

Operation
Apply control voltage to terminals 29 and 30 of the terminal
strip on the right side of the breaker. When the applied
control voltage is above 80% of the UVR's rated value, the
breaker can be closed. When the voltage drops to 35–60% of
the rated value, the UVR will trip the breaker.
