WARNING
IMPROPER INSTALLATION, OPERATION AND
MAINTENANCE
Ensure only qualified personnel install, operate, service
and maintain all electrical equipment.
Failure to comply with these instructions could
result in death or serious injury.
GENERAL INFORMATION
Optional accessories are interchangeable across all
EntelliGuard E power circuit breakers, regardless of nominal
rating or envelope/frame size. Each accessory incorporates
easy-fit design features for quick installation, either at the
factory or in the field (Fig. 6.1).
NOTE: Replacement accessories have an “R” at the end of
the catalog number as shown.

INDIVIDUAL ACCESSORIES
Motorized Spring Charging Unit
The unique motor/gearbox unit is specially designed to
operate with the full range of EntelliGuard E. It is easily fitted
with three heavy-duty bolts. After a breaker close operation,
the unit automatically recharges the spring and makes it
ready for immediate open and re-close should the need
arise. High speed recharging ensures that the springs are
fully charged within approximately three seconds following
a release. All electrically operated (EO) ANSI/UL breakers are
equipped with “Spring Charged” contacts (GSCC1R) for
status indication (Table 6.1).

 Spring charge time = 3 sec max.
 Recommended fuse amps: contact factory.
 Duty cycle = 2/min.
 Envelope 1 motors: running VA ~ 350 VA; inrush = 2 to 3
times.
 Envelope 2 motors: running VA ~ 560 VA; inrush = 2 to 3
times.
Circuit Breaker Closing Coil
Easy-to-fit, clip-on closing coil with simple, plug-in
connections is available. The closing coil offers electrical
remote release of the spring charged closing mechanism. A
standard anti-pump safety feature ensures that the remote
signal must be released before further close commands are
allowed.

 Duty cycle = 2/min.
 Closing coil inrush = 350 VA.
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.

 Pickup range = 55%-110%.
 Duty cycle = 2/min.
 Inrush = 480 A (ac).
 Holding = 60 VA (ac).
Remote Operation Coil Combination
Each breaker accepts a maximum of three coils shown in
Table 6.4. All coils are mounted from the front and snap onto
the mechanism after the fascia is removed.
