Abstract
A circuit breaker includes a conductor, a fixed contact connected to the conductor, and an arc runner disposed on the conductor adjacent the fixed contact. The arc runner includes a first portion abutting the fixed contact and a second portion disposed in a recess of the circuit breaker housing. The arc runner is adapted to draw an arc from the fixed contact. A circuit breaker operating mechanism cooperates with a movable contact for opening and closing the fixed contact and the movable contact. An arc chute is adjacent the arc runner. A trip unit cooperates with the operating mechanism to trip open the fixed and movable contacts.
