Abstract
A normally open close switch and a normally open arming switch are connected in series with a closing solenoid operatively coupled with hook apparatus for releaseably holding breaker movable contacts in a hooked open position against the closing force of a charged breaker operating mechanism. An arm actuates the arming switch in response to the movable contacts assuming their hooked open position, such that subsequent actuation of the close switch effects closing solenoid activation of the hook apparatus to release the movable contacts from their hooked open position. A holding solenoid, wired in shunt with the arming switch, prevents the arm from reactuating the arming switch in the event of sustained actuation of the close switch.
