Abstract: A circuit breaker assembly includes a circuit breaker cassette having a connector receiving zone, and a housing receptive of the circuit breaker cassette. The housing includes a connector mounting member. A circuit breaker connector member snap-fittingly extends into the connector receiving zone through the connector mounting member joining the circuit breaker cassette and the housing.

Abstract: A circuit breaker including a case, a trip mechanism, and a trip lever moveable between a first position and a second position. The trip lever includes a first end selectively contacting the trip mechanism and a second end opposite the first end. The circuit breaker also includes a biasing device including a housing coupled to the case and a lever arm coupled to the housing. The lever arm includes an engagement surface in contact with the second end and configured to move between an initial position corresponding to the first position and a final position corresponding to the second position. The biasing device also includes a bias member extending between the housing and the lever arm and biasing the engagement surface against the second end. The lever arm exerts a first torque in the first position and exerts a second torque different from the first torque in the second position.

Abstract: A magnetic trip mechanism for a circuit breaker includes an electrically conductive strap having a first wall portion and a second wall portion that define an interior space therebetween. Also included is a flux block disposed at least partially within the interior space, and movable in response to a short circuit condition of the circuit breaker. Further included is a trip lever operatively coupled to the flux block. Yet further included is a trip latch moveable between a latched condition and an unlatched condition with a handle, wherein rotation of the trip lever occurs in response to the short circuit condition and causes movement from the flux block to actuate the trip latch to the unlatched condition.
