Abstract
A circuit breaker can include a moveable electrical contact configured to be moved between an open position and a closed position, and a lever assembly configured to prevent the progressive closing of the moveable electrical contact to the closed position such that the lever assembly is configured to cause snap action closing of the moveable electrical contact at a charged position of a motorized slider.
Claims20
A motorized circuit breaker comprising:
- a moveable electrical contact configured to be moved between an open position and a closed position;
- a motorized slider configured to move in first and second directions between first and second positions;
- and
- a lever assembly configured to prevent progressive closing of the moveable electrical contact to the closed position such that the lever assembly is configured to cause snap-action closing of the moveable electrical contact at a charged position of the motorized slider, the lever assembly including:
- a kicker lever having a kicker configured to cause the moveable electrical contact to move to the open position, wherein the motorized slider is configured to push the kicker lever to the first position to cause the moveable electrical contact to move to the open position;
- and
- a catch lever configured to allow the motorized slider to decouple from the kicker lever, hold the kicker lever, and be moved by the motorized slider to release the kicker lever in the second position to cause the snap-action closing of the moveable electrical contact.

A motorized circuit breaker comprising:
- a moveable electrical contact configured to be moved between an open position and a closed position;
- and
- a lever assembly configured to prevent progressive closing of the moveable electrical contact to the closed position such that the lever assembly is configured to cause snap-action closing of the moveable electrical contact at a charged position of a motorized slider of the motorized circuit breaker, wherein the lever assembly comprises:
- a kicker lever having a kicker configured to cause the moveable electrical contact to move to the open position, wherein the motorized slider is configured to push the kicker lever to a first position to cause the moveable electrical contact to move to the open position;
- and
- a catch lever configured to allow the motorized slider to decouple from the kicker lever, wherein the catch lever is configured to hold the kicker lever and to be moved by the motorized slider to release the kicker lever in a second position of the motorized slider to cause snap action closing of the moveable electrical contact.

A motorized circuit breaker comprising:
- a moveable electrical contact configured to be moved between an open position and a closed position;
- a lever assembly configured to prevent progressive closing of the moveable electrical contact to the closed position such that the lever assembly is configured to cause snap-action closing of the moveable electrical contact at a charged position of a motorized slider of the motorized circuit breaker;
- and
- a moveable blade having the moveable electrical contact thereon or attached thereto and configured to make contact with a fixed electrical contact in the closed position, and to be separated from the fixed electrical contact in the open position, wherein the blade is biased to the closed position,
- and wherein the lever assembly comprises:
- a kicker lever having or connected to a kicker, wherein the kicker is configured to contact the blade to move the blade to the open position, wherein the kicker lever is configured to move the kicker to move blade to the open position,
- wherein the motorized slider is configured to move between at least a first position and a second position, wherein the motorized slider is shaped to contact and move the kicker lever in a first direction toward the first position to consequently move the blade to the open position, wherein the motorized slider is configured to move in a second direction away from the kicker lever toward the second position;
- and
- a catch lever configured to engage the kicker lever to prevent the kicker lever from allowing the blade to move toward the closed position, wherein the motorized slider is configured to separate from the kicker lever in the second direction when the kicker lever is engaged to the catch lever, wherein the motorized slider is configured to contact the catch lever to move the catch lever to disengage the catch lever from the kicker lever after the motorized slider has separated from the kicker lever in the second direction to allow the kicker lever and the kicker to snap release the blade to allow snap closing of the moveable electrical contact to the fixed electrical contact.
