Abstract:
A solenoid operated remote resetting device for an electrical overload protection device having a manual reset mechanism, said resetting device comprising:a housing defining a hollow interior and further defining a generally rectangular opening for communication between said hollow interior and the outside of said housing;a solenoid being enclosed within said housing, said solenoid having a movable plunger;a printed circuit board enclosed within and held in fixed relationship to said hollow interior of said housing;a solenoid activation circuit mounted on said printed circuit board, said solenoid activation circuit including a rectifier having two input terminals and a solenoid power circuit having a pair of silicone controlled rectifiers, each of said silicone controlled rectifiers being connected to one of said input terminals for alternately providing power to said solenoid during alternating half cycles of an unrectified alternating current at said input terminals, said solenoid activation circuit being activatable in response to a signal from a remote activating means, the remote activating means signal providing operating power for said solenoid activation circuit, said solenoid activation circuit providing operating power to said solenoid for a preselected length of time not determined by the length of time said solenoid activation circuit is receiving the remote activation signal;a mechanical operator attached to said movable plunger for common movement thereof, said mechanical operator having an operating arm extending outwardly through said rectangular opening in said housing for engaging the manual reset mechanism of the electrical overload protection device; andmeans for mounting said housing securely on an outside surface of the electrical overload protection device such that said operating arm, when operated, will engage the manual reset mechanism.
