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 6.16 and 6.17).
