Abstract: A preferred embodiment of an interrupter assembly for a circuit breaker includes a first contact, a conductor, and a second contact mounted on the conductor. The second contact and the conductor are movable in relation to the first contact between a first position wherein the first and the second contacts are in electrical contact, and a second position. The interrupter assembly also includes a body having a first and a second half each having a plurality of recesses formed therein. The recesses form chambers within the body for holding insulating fluid when the first and the second halves are mated. The body receives the second contact and the conductor so that the conductor and the second contact are drawn through the chambers as the second contact moves from the first to the second position.
