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 inslulative 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.

La présente invention concerne un coupe-circuit qui comprend des contacts fixes et mobiles, un mécanisme de fonctionnement comprenant un bras mobile portant le contact mobile, une chute d'arc comprenant une pluralité de premières et secondes plaques d'arc espacées et un moteur à fentes. Une structure de moteur à fentes est disposée autour des contacts et d'une partie du bras mobile. Un logement isolant couvre et isole au moins substantiellement la structure du moteur à fentes du bras et des contacts amovibles. Le logement isolant comprend une base et une paire de bras disposée à partir de là. Chacun des bras comprend une première partie placée près des premières plaques d'arc et une seconde partie, plus petite, placée près des secondes plaques d'arc. Un espace s'étendant depuis la première partie, qui n'est pas occupée par la seconde, est généralement occupé par une partie des secondes plaques d'arc. La seconde partie forme une protection contre les débris entre les secondes plaques d'arc et le mécanisme de fonctionnement.
