Bell Alarm With Lockout
The bell alarm with lockout module combines both the bell
alarm and a manual lockout function. The bell alarm switch
operates identically to the standard bell alarm module,
except that the mechanical pop-out target must be manually
reset before the breaker can be closed.
Operation of the bell alarm with lockout module can be in
dependently set by means of setting the DIP switches at the
rea r of the M icroVersaTrip P/usTM and PM™ trip units. For the
Power+™ trip unit, the bell alarm with lockout module oper
ates only when an overcurrent (including g round fault) trip
occurs. Current ratings of the single SPDT switch a re identical
to the bell ala rm module.

Undervoltage Release Module
The undervoltage release is an electronic module used to
open the circuit breaker when the monitored voltage d rops
below 3 5-60% of its rated value. The undervoltage release
"resets" when the monitored voltage is re-established allow
ing the circuit breaker to reclose (the sealing voltage of the
UVR is 60-85% of its rated voltage).

An undervoltage release trip operation is produced by the
Power+, MicroVersaTrip Plus or MicroVersaTrip PM trip unit in
response to a signal from the undervoltage release module.
This a llows the trip unit to record, display, distinguish and
communicate (in MicroVersaTrip PM trip units) that the break
er opening event was due to undervoltage release. Opera
tion of the undervo/tage release module will prevent breaker
contact closure, i.e. "kiss-free" o peration. When energized,
the undervo/tage release su24 Vdc power to the Mi
croVersaTrip Plus and PM trip units to power the display.
The undervoltage release module is ava ilable in a wid e range
of control and power system voltages ranging from 12 Vdc
to 600 Vac. U ndervoltage release modules used with 480
Vac and 600 Vac control power are supplied with a 50 VA
control power transformer which mounts externally from the
breaker. These transformers provide a n output of 120 Vac,
50/60 Hz. to the UVR modules. (See outline d rawings in Physi
cal Data Section.)

Time Delay Module for UVR
The time delay module prevents nuisance tripping d ue to
momentary loss of voltage. Cat. N o. SPUVTD has 0.1 to 1.0
seconds delay. The module has 120 Vac input and 125 Vdc
output and must be used with the 125 Vdc UVR (Cat. No.
SPUV125DC).
