Abstract
A circuit breaker includes an electrically insulating housing, an arc chamber, line and load terminals, separable contacts in series with the terminals, and an operating mechanism. The open position of the separable contacts causes arcing therebetween and the development of ionized gases. The housing includes a first wall, an opposite second wall, a pair of side walls, and a barrier wall forming a compartment for containing the line terminal. The barrier wall has an opening between the arc chamber and the compartment. The first wall has an aperture aligned with the line terminal. A baffle member includes a base portion, a flap and a pair of leg members. The flap extends over the aperture and is deflectable by a tool inserted through the aperture for adjustment of the line terminal. The leg members engage the side walls, thereby supporting the baffle member within the compartment.
