A motor drive for a molded case circuit breaker, comprising:
- an actuator for assuming a plurality of positions;
- a lever having a first end and a second end, the lever coupled to the actuator and responsive to the action of the actuator;
- and
- a cam rotatable about an axis and coupled to the molded case circuit breaker, the cam juxtaposed proximate the lever, the lever operative to position the cam in a plurality of positions.
A method moving an operating handle in a circuit breaker, the operating handle being coupled to a cam, the cam being positioned proximate a lever, the method comprising:
- biasing the lever in a first direction relative to a rotational axis of the cam;
- moving the lever to rotate the cam in a first rotational direction about the rotational axis;
- biasing the lever in a second direction relative to the rotational axis of the cam;
- and
- moving the lever to rotate the cam in a second rotational direction about the rotational axis.
A molded case circuit breaker including:
- a housing;
- an operating mechanism extending therefrom;
- and
- a motor drive coupled to the operating mechanism, the motor drive comprising
- an actuator for assuming a plurality of positions;
- a lever having a first end and second end thereof, the lever coupled to the actuator and responsive to the action thereof;
- and
- a cam rotatable about an axis and coupled to the molded case circuit breaker, the cam juxtaposed proximate the lever, the lever operative to position the cam in a plurality of positions.
