A remotely controllable circuit breaker device for interrupting power in a circuit path between a source (14) and a load (16) includes local and remote monitoring capabilities and a worm gear mechanism (56) for reliable control of the interruption mechanism. The device includes a first contact (18) and a second contact (20) cooperatively arranged in the circuit path so as to provide current from the source (14) to the load (16). At least one of the contacts (20) are movable for interrupting the power provided to the load (16). The worm gear mechanism (56) includes a motor (50) with a rotatable shaft (52) which responds to open and closed control signals generated from a remote location, and a gear (62), rotatably responsive to the rotatable shaft (52), for controlling the movable contact (20) so that the circuit path is interrupted and established, respectively. The worm gear mechanism (56) controls the movable contact (20) using a coupling arrangement (68), which has a first part coupled to the movable contact (20) and a second part coupled to the gear (62). |
