Abstract: A circuit interrupter includes a handle, an operating linkage, and a spring that are situated on a housing, with the spring extending between the handle and the operating linkage. The circuit interrupter is movable among an ON position, an OFF position, and a TRIP position, and the operating linkage includes a contact arm that is pivotable with respect to the housing to move a movable contact between an OPEN position and a CLOSED position with respect to a stationary contact. The handle has a toggle point, and when the spring is situated at a first side of the toggle point, the spring biases the contact arm to the ON position. When the spring is situated at a second side of the toggle point, the spring biases the contact arm to the OFF position or the TRIP position.

Abstract: A circuit breaker assembly includes a circuit breaker including a housing and a handle extending from the housing, with the handle being movable between an on position and an off position. The assembly includes a handle mechanism connected to the housing of the circuit breaker. The handle mechanism includes a base, a slider slidably connected to the base and including first and second spaced apart arms with the handle of the circuit breaker at least partially between the first and second arms, and a spring on the slider. The slider is movable between a first position with the handle in the on position and a second position with the handle in the off position. The handle engages the spring with the handle in the on position and the slider in the first position.

Abstract: A shield apparatus and a resultant circuit interrupter are disclosed, wherein the shield apparatus includes a shield apparatus base and a protection apparatus, with the protection apparatus including a shield that helps to direct an electrical arc along a flow path through a number of passages and that will help to enable dissipation of the arc and the plasma generated thereby. The shield apparatus is mountable to a portion of the housing of the circuit interrupter within its interior, and the shield is situated adjacent at least a first passage.
