Abstract
A circuit breaker includes fixed and movable contacts, an operating mechanism including a movable arm carrying the movable contact, an arc chute including a plurality of spaced apart first and second arc plates, and a slot motor. A slot motor structure is disposed about the contacts and a portion of the movable arm. An insulative housing at least substantially covers and insulates the slot motor structure from the movable arm and contacts. The insulative housing includes a base and a pair of arms disposed therefrom. Each of the arms includes a first portion disposed proximate the first arc plates and a second smaller portion disposed proximate the second arc plates. A space extending from the first portion, not occupied by the second portion, is generally occupied by a portion of the second arc plates. The second portion forms a debris shield between the second arc plates and the operating mechanism.
