Claims

[Scope of utility model registration request]

(1) In a circuit breaker in which a breaker is housed in a housing, an arc exhaust port is formed in the side wall of the casing, and this arc exhaust port is located closer to the power source than the notch in the arc extinguishing plate of the breaker mechanism. A circuit breaker characterized by:

(2) The circuit breaker according to claim 1, which is a registered utility model, wherein an exhaust passage extending from the arc discharge port along the side wall of the casing is formed in the side wall.

(3) The circuit breaker according to claim 2, wherein the casing includes a cover and a base joined to the cover, and an exhaust passage is formed at the joint surface of the cover and the base.

(4) The circuit breaker according to claim 2, wherein the exhaust passage is formed in either the cover or the base in the form of a tunnel.

(5) The circuit breaker according to claim 1, wherein an exhaust passage extending from the arc discharge port along the side wall of the casing is formed in an attachment attached to the side wall.

(6) A circuit breaker according to claim 2, 3, 4, or 5 of the utility model registration claim, in which the exhaust passage is opened on the side where the load-side satin is disposed.
