Abstract
An arc extinguishing structure for a circuit breaker (2) wherein an arc chute is provided with a pair of transverse barrier plates (38) spaced apart to provide a centrally located opening (40) and spaced away from an upstanding wall (4a) of the breaker housing (4) so as to direct ionized gases associated with an electric arc drawn between separating contacts (8,20) through the arc plates (36) and central opening (40) against the upstanding wall (4a) thereby to be redirected along the wall (4a) and exhausted to the atmosphere through unrestricted openings (6a,4b) provided at opposite upper and lower ends of the wall. The barriers (38) project into the areas of the passageways (6a,4b) to prevent direct access to the switch contacts (8,20) through the passageways and to increase the length of the exhaust path for the arc gases.
