ABSTRACT:
This sectionalizer comprises a movable current-carrying member carrying a first contact that is engageable with a second contact when the sectionalizer is closed. Overcenter toggle means holds the current-carrying member in its closed position when the toggle means is in an overcenter condition but is ineffective to hold the current-carrying member in said closed position when the toggle means is driven out of its overcenter condition. Electronic control means develops a pulse of electrical energy when predetermined conditions have occurred in the circuit through the sectionalizer. A resettable actuator for said overcenter toggle means comprises operating spring means, permanent magnet means for holding the operating spring means in a charged condition, and electromagnetic means effective when energized by said pulse of electric energy for reducing the holding force provided by the permanent magnet means sufficiently to allow the operating spring means to discharge and drive the overcenter toggle means out of its overcenter condition, thus allowing the current-carrying member to move toward open condition.
