Introduction

The Bell Alarm with Lockout module, shown in Figure 1, can
be installed in 800–4000 ampere frame Power Break® II
circuit breakers. Its function is to prevent reclosing of the
breaker after a trip until the Bell Alarm with Lockout is reset.
It can only be reset by pressing the reset button on the top of the
module. This module also provides a switch to remotely indicate
that the circuit breaker has tripped.

Figure 1. Bell Alarm with Lockout.

In addition to activation by protection trips, the Bell Alarm with
Lockout 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 MicroVersaTrip Plus or MicroVersaTrip PM Trip Unit
can configure the Bell Alarm with Lockout accessory to activate
when a Shunt Trip or Undervoltage Release trip occurs. The
Accessory Configuration section below describes how this can be
done
The Power+™ Trip Unit activates the Bell Alarm with Lockout
for protection trips only.
The catalog numbers for the Bell Alarm with Lockout are listed
in Table 1.

Operation

The Bell Alarm with Lockout prevents reclosing of the breaker
after a trip until the reset button on the front of the module is
pressed. This trip can be caused by an overcurrent condition
detected by the Trip Unit. This trip can also be generated by
the Shunt Trip, Shunt Trip with Lockout, or Undervoltage
Release, if installed with a MicroVersaTrip Plus or MicroVersa-
Trip PM Trip Unit and if the appropriate DIP switches have
been set on the back of the Trip Unit. Power+ Trip Units can
only activate the Bell Alarm with Lockout for a protection trip.
In addition, the Bell Alarm with Lockout provides normally
open (NO) and normally closed (NC) alarm outputs available
at the terminal block on the right side of the breaker, as
illustrated in Figure 2. These outputs are returned to their
normal state when the Bell Alarm with Lockout reset button is
firmly pressed.
