Abstract
The present invention relates to an interrupter for a circuit breaker for a transmission or distribution line which can distribute and weaken an arc resulting from separation of contacts, can reduce loss of the contacts by the arc, and can improve interruption performance, when an abnormal current such as overcurrent is generated. A plurality of horizontal loops of conductive path are formed on a fixed electrode and a movable electrode, thereby forming a plurality of vertical magnetic fields in parallel with a generation direction of the arc. When the arc is generated between a fixed contactor and a movable contactor respectively connected to the fixed electrode and the movable electrode, the arc can be evenly distributed on the fixed and movable contactors. At the same time, a movement of the arc can be interrupted.
