WL Circuit Breaker selection and application guide
Bell alarm contact and reset coil
The bell alarm contacts are mechanically activated by the trip
unit solenoid. If a breaker trip condition occurs, the bell alarm
form-C contacts will change state closing or opening a user circuit
wired to the secondary terminal block. The contacts can be locally
reset to their original position by manually resetting the trip unit
solenoid or through the use of a reset coil which can be energized
remotely. See breaker wiring diagram for supply terminal locations.
Non-automatic (manual) reset trip units can not be used with the
reset coil option.

Breaker accessories and options
Close coil
To remotely close the WL breaker, a close coil may be used with a
momentary electrical source. Only one close coil specific to the
supply voltage can be used per breaker. Charging springs must be
charged and breaker open prior to use of close coil. See breaker
wiring diagram for supply terminal location.
Breaker push button lock-outs
If conscious use of the breaker close or open push button is
required. A finger or hand tool shroud option can be added to
the breaker front cover. Shrouds may be used in combination
or like configuration.
If push button lock-out is required. Transparent padlock covers
for unauthorized or mechanical lockout can be installed in lieu
of the shroud option. Two padlocks may be used with a latch
diameter of 3/8 inch maximum (padlocks by others).
Racking handle key lock
A draw-out breaker can be key locked (optional) or padlocked
(standard not shown) in three racking positions; connect,
test or disconnect. Key lock cylinders are available in Kirk or
Superior types and uniquely keyed.
