ABSTRACT:
A remotely controllable circuit breaker device for interrupting power in a circuit path between a source and a load includes local and remote monitoring capabilities and a worm-gear mechanism for reliable control of the interruption mechanism. The device includes a first contact and a second contact cooperatively arranged in the circuit path so as to provide current from the source to the load. At least one of the contacts are movable for interrupting the power provided to the load. The worm gear mechanism includes a motor with a rotatable shaft which responds to open and closed control signals generated from a remote location, and a gear, rotatably responsive to the rotatable shaft, for controlling the movable contact so that the circuit path is interrupted and established, respectively. The worm gear mechansim controls the movable contact using a coupling arrangement, which has a first part coupled to the movable contact and a second part coupled to the gear.
