Circuit Breaker Closing Coils – Standard and Commanded
Two, easy-to-fit, clip-on closing coil options with simple,
plug-in connections are available. Both options offer
electrical remote release of the spring charged closing
mechanism. Both options include a standard anti-pump
safety feature ensuring that the remote signal must be
released before further close commands are allowed. The
Command Close Coil additionally provides for local
electrical command of the accessory and remote
command over communications via the EntelliGuard trip
unit (Table 6.2).

Closing coil inrush = 350 VA.


Command Operation Module
This module energizes the closing coil to cause the breaker
to close whenever control power is applied to the
accessory and when commanded from the breaker trip
unit or breaker front panel push button (electrical closing).

Shunt Trip (ST)
Energizing the shunt trip, via local or remote input, will
instantaneously activate the circuit breaker mechanism,
ensuring a rapid open operation. The standard auxiliary switch
ensures automatic isolation whenever the circuit breaker is
open. The shunt trip release is a straightforward, field installable
accessory available in wide range of voltages (Table 6.3).

and ANSI DC Rating Applications.

Status Indication Switch (Coil Signaling Contact)
A plug-in module is available to provide status indication via
the secondary disconnects and trip unit. Coil Signaling
Contacts are available for closing coils, shunt trips and under
voltage releases, see Table 6.4. Contac t is mounted on top of
the Accessory Device.

Under Voltage Release (UVR) With Fixed Time Delay

The UVR instantaneously activates the circuit breaker trip
mechanism when the source voltage drops below the low
voltage threshold. The UVR is also a simple, field installable
device. NOTE: This accessory acts as a permissive; it is a no-
voltage/no-close device. The circuit breaker cannot be closed
(manually or electrically) unless the under voltage release coil
is energized above the required threshold. The UVR shunt trip
with fixed time delay is specifically intended for applications
where a delay period (ride-through) is required due to
potential voltage events. The delays are 50 ms when system
voltage drops to 50% and 20 ms when system voltage drops
below 50%. See Table 6.4. (A Time Delay Module is also
available, see next page).
