::Jectrical Opening
All breakers, manual and electrical, are equipped with a
mechanical TRIP button located on the breaker escutcheon.
Electrical breakers include a shunt trip device for remote
opening.

This electrically operated breaker utilizes a motor to auto­
matically keep the closing springs in a charged state.
Whenever the control solenoid is energized, its operation
releases the closing springs, closing the breaker contacts.
(For typical electrical circuit see pg. 38)
The i nitiation of the closing operation for both of the above types of breakers is by closing of a contact of a remote switch,
relay or a close button in the front escutcheon if the breaker is so equipped. The breakers control schemes have an anti­
pump feature which allows only one closure of the breaker for a single operation of the closing contact no matter how long
the contact may be held closed . This prevents the repeated operations that would ensue if one of the automatic trip devices
was activated at the time of closing. A manual closing handle is provided for maintenance purposes. All electrically operated
breakers close within five cycles.

This electrically operated breaker closes whenever the
closing solenoid coil is energized. This causes an upward
movement of the solenoid armature which charges the
springs to a predetermined over-center point for closing.
