Abstract
An air circuit breaker is disclosed. The air circuit breaker according to an embodiment of the present disclosure includes a cover magnet unit. The cover magnet unit is directly coupled to an upper cover which forms the outer appearance of the air circuit breaker. The cover magnet unit is positioned adjacent to a fixed contact and forms a magnetic field. Due to the formed magnetic field, an electromagnetic force in a direction toward an arc extinguishing unit is applied to a generated arc. Accordingly, the generated arc may be rapidly moved and extinguished. The cover magnet unit is inserted into a surface of the upper cover and is not exposed to the outside. Therefore, the generated arc is not in contact with the cover magnet unit. As a result, the cover magnet unit is not damaged by the generated arc.
