Abstract

An air circuit breaker with an arc extinguishing apparatus comprising: a frame having a receiving space (112) therein; a fixed contact (120) disposed inside the frame; a movable contact (130) disposed to be in contact with or separated from the fixed contact; and an extinguishing apparatus (150) which includes a chamber member disposed in the frame and having an outlet (153) formed at one side thereof, a plurality of grids (171) disposed in the chamber member to be spaced apart from one another, and a cloth filter member (180) formed of fabric and disposed between the outlet and the grids to prevent fragments which are generated by arcs from being scattered, whereby the air circuit breaker can be fabricated with low cost, and also fragments generated due to arcs can be prevented from being excessively scattered to the exterior.
