Power Break® II Circuit Breaker Accessories
Undervoltage Release
1
The Under voltage Release is installed in the accessory
compartment through the front of the circuit breaker in the
position shown in Figure 2.
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.

Use the following procedure to install the UVR accessory
into the UVR slot in the accessory compartment of the
circuit breaker:
Open the hinged door over the accessory compart-
ment and Trip Unit.
To remove an existing accessory module, loosen the
accessory locking screw and pull the module out with
the Rating Plug Removal Tool (catalog number
TRTOOL).
Insert the UVR accessory into the proper slot, as
illustrated in Figure 3. The UVR accessory is keyed for
the correct slot in the accessory compartment. If the
accessory cannot be fully seated in the compartment,
check that the compartment position is correct.
Tighten the locking screw on the front of the accessory
until it is snug (torque of 9 in-lb.)
CAUTION: Overtightening the locking screw may damage
or distort the case of the accessory.
ATTENTION: Le serrage excessif de la vis de verrouillage
peut déformer le boîtier d’accessoire.
If the breaker is equipped with a MicroVersaTrip Plus
or MicroVersaTrip PM Trip Unit, the UVR accessory can
be configured to activate installed Bell Alarm Alarm
Only or Bell Alarm with Lockout accessories when a
UVR trip occurs, with the procedure described in the
Accessory Configuration section.
Connect the control wiring for the UVR to terminals 29
and 30 at the terminal block on the right side of the
breaker.
Test the UVR to ensure proper operation, according to
the procedures below.
Reconnect power to the circuit breaker and any other
accessories.
Accessory Configuration
This section only applies if Bell Alarm–Alarm Only or Bell Alarm
with Lockout accessories are installed in the breaker, along
with a MicroVersaTrip Plus or MicroVersaTrip PM Trip
Unit. If the breaker is equipped with a Power+ Trip Unit, the
factory default settings, listed in Table 2, can not be changed.
The UVR accessory can be configured to activate the Bell
Alarm–Alarm Only or Bell Alarm with Lockout accessories if a
UVR trip occurs. The configuration can be changed by removing
the Trip Unit from the breaker, setting the DIP switches on the
rear of the Trip Unit, and reinstalling the Trip Unit. Figure 4
illustrates the Trip Unit read DIP switches and their functions.
Table 2 lists the switch functions and the factory settings for
each.
