Power Break® II Circuit Breaker Accessories
Undervoltage Release 480 & 600 Vac
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 480 and 600 Vac
applications are listed in Table 1. Voltage and current ratings
in Table 1 are given at the input of the transformer. The
voltage and current ratings at the input of the UVR accessory
are equal to that of the SPUV120AC accessory. Input voltage
is 120 Vac, peak inrush current is 3 A, and the nominal RMS
current is 80 mA.
Operation
Apply control voltage to the primary of the supplied step-
down transformer. The secondary of the transformer is
connected to terminals 29 and 30 of the terminal strip on the
right side of the breaker.
