• Duty cycle = 2/min.
• Closing coil inrush = 350VA.
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
Energizing the shunt trip (ST), via local or remote input, will
instantaneously activate the circuit breaker mechanism,
ensuring a rapid open operation. The shunt trip is
continuously rated and does not require an auxiliary switch
in series with the coil. The shunt trip is a straightforward,
field installable accessory available in wide range of
voltages. See Table 4.3.

and ANSI DC Rating Applications.

• Pickup range = 55%-110%.
• Duty cycle = 2/min.
• Inrush = 480A (ac), 480W (dc).
• Holding = 60VA (ac), 50W (dc).
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 (Table 4.4). Contact is mounted on top of the
Accessory Device. One of the low signal (Hi-Fi) contacts is
always wired to the tip Unit.

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 undervoltage
release coil is energized above the required threshold. The
undervoltage release 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
50msec when system voltage drops to 50% and 20msec
when system voltage drops below 50% (Table 4.5).
