Bell Alarm with Lockout
The Bell Alarm provides remote indication that the circuit
breaker has opened because of an electrical fault. The
Lockout feature is integral to the trip unit. When a Bell Alarm
is supplied with the breaker, the Trip Unit dial is set and
locked to the manual position. In order to re-close the
breaker, the Lockout button must be pushed in/reset on the
Trip Unit 1-Form C contact (Tables 4.21 and 4.22).

Inputs and outputs to the circuit breaker are wired through
secondary disconnects located on either the top or the side
(Envelope 1 only) of the breaker. The plug-style secondary
disconnects engage mating disconnects in the breaker
cubicle when the breaker is in the TEST or CONNECT position.
Up to 78 points are available so that all breaker accessories
can be wired to dedicated disconnect points (Tables 4.24
through 4.29). Block B is ordered separate for cassettes, Cat.
