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 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.
