Abstract: An arc bypass assembly for use in a circuit breaker includes: an arc chute including a base, two arc sides extending from the base, and a plurality of arc plates arranged within the two arc sides, the arc chute structured to dissipate an arc upon opening of primary contacts of the circuit breaker during a high current event; an arc horn extending outwardly from a first edge of the base of the arc chute toward a primary stationary contact coupled to a line-in conductor, the arc horn structured to attract the arc; and an arc bypass wire coupled to the base of the arc chute at one end and to a secondary stationary arm of the circuit breaker at another end, where the arc bypass assembly is structured to redirect a portion of current generated during the high current event to the load.

Abstract: A slot motor for use with secondary contacts in a circuit breaker includes a top slot motor component structured to be attached to a moving arm of the secondary contacts; and a U-shaped bottom slot motor component including a base and a pair of legs extending upward from the base, the U-shaped bottom slot motor component structured to be separated from the top slot motor component by vertical gaps between the top slot motor component and ends of the pair of legs, wherein the slot motor is structured to generate a magnetic field producing a force to maintain the secondary contacts in closed position upon passing high current through the moving arm.
