WL Circuit Breaker
Factory Installed Options
Status contact
A status contact is a mechanical switch that is suitable for
monitoring an undervoltage trip or second shut trip coil
position. The contact will be wired to the secondary contacts
of the breaker for customer connections or wired to the Breaker
Status Sensor (BSS) if communications is installed on the
breaker. Contact is 1NO configured.

Spring-charging motor
The spring charging motor is used to automatically charge the
breakers closing spring so the breaker is suitable for closing on
command. Motor charging is typically used for remote breaker
operation or as an alternative to local manual charging. The
motor assembly can be easily installed in the field and includes
an automatic cut-off switch which disconnects the current upon
full charge of the closing spring mechanism.

Undervoltage release
In the event of loss or low level control circuit voltage, an
undervoltage release may be used to automatically open
the circuit breaker. To prevent nuisance breaker openings
from temporary voltage dips, a separate adjustable time-
delay undervoltage release is also available.
