Abstract
A circuit breaker drive is disclosed. The circuit breaker drive includes an actuator for assuming a plurality of positions and a lever coupled to the actuator and responsive to the action of the actuator. The circuit breaker drive also includes a cam rotatable about an axis, the cam is juxtaposed proximate the lever, and the lever is operative to rotate the cam about the axis. The circuit breaker drive further includes a rack coupled to the cam and to an operating handle of the mol circuit breaker. Rotation of the cam about the axis drives the rack to move the operating handle.
Claims21
A circuit breaker drive comprising:
- an actuator for assuming a plurality of positions;
- a lever coupled to the actuator and responsive to the action of the actuator;
- a cam rotatable about an axis, the cam juxtaposed proximate the lever, the lever operative to rotate the cam about the axis;
- and
- a rack coupled to the cam and to an operating handle of the circuit breaker, rotation of the cam about the axis drives the rack to move the operating handle.
A circuit breaker including:
- a housing;
- an operating handle extending from the housing;
- and
- a drive coupled to the operating handle, the drive comprising:
- an actuator,
- a lever pivotally coupled to the actuator,
- a cam rotatable about an axis, the cam juxtaposed proximate the lever, the lever is operative to rotate the cam about the axis, and
- a rack coupled to the cam and the operating handle, rotation of the cam about the axis drives the rack to move the operating handle.
A drive for moving a handle of a circuit breaker between an ON position and an OFF position, the drive comprising:
- cam rotatable about an axis,
- a rack coupled to the cam and to the operating handle, rotation of the cam about the axis drives the rack to move the operating handle between the ON position and the OFF position,
- a lever juxtaposed proximate the cam, the lever includes an end for driving the cam about the axis,
- a spring extending between the rack and the lever, the spring biases the end of the lever to a first side of the axis when the rack is the ON position, and the spring biases the end of the lever to a second side of the axis when the rack is in the OFF position.
