Abstract
A molded case circuit breaker of relatively narrow width is afforded dramatically increased current interrupting capacity by providing shielding against the electromagnetic field developed as the result of short circuits flowing through a contiguous circuit breaker. Additionally, an arc runner is added to cooperate with an improved arc chute construction in controlling to extinction the arc developed incident to an interruption. The case is also vented to relieve the internal gas pressure during arcing.
