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 bel l a l a rm module,
except that the mech a n ical 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 un its. 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 a la rm module.

U ndervoltage Release Module

The undervoltage release is an e lectronic module used to
open the circuit b reaker when the monitored voltage d rops
below 3 5-60% of its rated value. The undervoltage release
"resets" when the mon itored voltage is re-esta blished allow­
ing the circuit b reaker 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 l lows the trip unit to record, display, distingu ish and
commun icate (in Mic roVersaTrip PM trip units) that the break­
er opening event was due to undervoltage release. Opera­
tion of the undervo/tage release module will prevent b reaker
contact closure, i.e. "kiss-free" o peration. When energized,
the undervo/tage release supplies +24 Vdc power to the Mi­
croVersaTrip Plus and PM trip un its to power the display.
The undervoltage release module is ava ilable in a wid e range
of control and power system voltages ranging from 1 2 Vdc
to 600 Vac. U ndervoltage release modules used with 480
Vac and 600 Vac control power a re supplied with a 5 0 VA
control power transformer which mou nts externally from the
b reaker. These transformers p rovide a n output of 120 Vac,
5 0/60 Hz. to the UVR modules. (See outl ine d rawings in Physi­
cal Data Section.)

Tim e Delay Mod u le 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 in put and 125 Vdc
output and must be used with the 125 Vdc UVR (Cat . No.
SPUV125DC).
