Abstract: Disclosed is an air circuit breaker. The air circuit breaker according to an embodiment of the present disclosure includes a CT magnet unit. The CT magnet unit is provided in the air circuit breaker to cover a movable contact point exposed to the outside. A CT magnet is provided inside a case that forms the outer shape of the CT magnet unit. The CT magnet independently forms a sub magnetic field or forms a main magnetic field together with an extinguishing magnet provided in an arc extinguishing unit. Due to the magnetic field formed by the CT magnet, an arc that is generated receives the application of an electromagnetic force directed toward the arc extinguishing unit. Accordingly, the generated arc can be quickly moved and extinguished.
