Internal and External Accessories

Table N: Electrical Operators

Electric Operators function to automatically charge the SB break-

er’s stored energy mechanism. Each operator includes a Remote

Closing Solenoid for closing the breaker from a remote location

and an electronic controller which provides anti-pump protection

and remote charging capability and indication. The Closing Coil

Interlock (CCX) option allows the customer to block the operation

of the closing coil by adding an external electrical contact/interlock

in the breaker’s closing coil circuit. A Shunt Trip or Under Voltage

Release should be ordered and priced separately for remote open-

ing of the breaker. UL listed for field installation.

Electrical Operators With Electric Close

Electric Operators with Local Electric Close provide an electric

close pushbutton on the breaker escutcheon that can be electri-

cally interlocked with an external control circuit. The Closing Coil

Interlock Option is also available on operators equipped with Local

Electric Close. Factory installation only. Note that “Push to Close”

and “Push to Open” pushbutton operators are provided on the

breaker escutcheon as standard.
