ABSTRACT:
A remotely controlled circuit breaker system incorporates a generally conventional circuit breaker having latch means which are moveable in a first direction for moving an operating member so that it is latched in closed circuit position, the operating member being adapted to be independently moveable in the same first direction for unlatching the member to permit the member to return to its open circuit position. A momentarily operable solenoid has a pawl pivotally mounted on the solenoid plunger. Spring means resiliently hold the pawl against a stop in a selected location relative to the latch means so that when the solenoid is momentarily actuated while the operating member is in open circuit position, the pawl engages the latch means and moves the operating member to its latched closed circuit position. However, if the operating member is in closed circuit position, actuation of the solenoid moves the pawl away from the stop and the spring means pivots and reorients the pawl so that it engages the operating member, thereby to unlatch the operating member for permitting it to return to open circuit position.
