MOLDED CASE CIRCUIT BREAKER WITH SINGLE SOLENOID OPERATOR FOR RECTILINEAR HANDLE MOVEMENT

摘要

42 51,655 A molded case circuit breaker includes a single coil solenoid operator for placing the handle of the circuit breaker in its ON position or in its OFF position. The solenoid operator includes a single coil solenoid formed by an electromagnet secured to a movable electromagnet drive plate and by an armature secured to a movable armature drive plate. The drive plates are disposed for rectilinear movement and are configured alternately to engage a formed trigger plate secured to the handle to move the trigger plate and the handle between the ON position and the OFF position of the handle. A pair of pivotable, bistable mechanical latches are configured to engage and stop further movement of alternate drive plates depending upon the state of the latches. Successive actuations of the single coil solenoid operator cause the handle to be placed alternately in its ON position or in its OFF position.
