摘要： PROBLEM TO BE SOLVED: To provide a circuit breaker that prevents intrusion of foreign matter while satisfactorily exhausting arc gas generated upon circuit breaking.
SOLUTION: Inside arc gas exhaust holes 9 and 10 formed in a casing 1 of the circuit breaker, ribs 15 and 17 for preventing intrusion of foreign matter having asymmetric inner and outer shapes are formed integrally with the casing 1 to apply an inner/outer asymmetric flow resistance to a flowing air stream. The ribs 15 and 17 preferably have a shape recessed toward the inside of the casing 1, and are more preferably V-shaped. This makes the intrusion of foreign matter difficult, without hindering the discharge of the arc gas. Any conventional dust barrier is no longer required and it is thus possible to reduce the number of components.
