Introduction
Command Closing Coil:
Command Close coil is used to switch ON the
Power Circuit Breaker remotely. When
commanded it releases the spring charged
mechanism thus ensuring a rapid connection of
the main contacts. The Command Close coil
offers an extended functionality in addition to all
the features of the standard closing coil.
Additional connections allow it to be wired out
through the trip unit to be commanded through
the communications bus. An optional electrical
close pushbutton that fits onto the breaker front
fascia is available to command the accessory
from the breaker directly.
