流回路用しゃ断器。(1) Equipped with a fixed contact fixed to a fixed contact stand attached to the inner bottom or inner wall of the case, and a movable contact that makes contact with and separates from the contact, and the arc generated between the two contacts is In a device that extinguishes an arc by being driven by the magnetic flux of a permanent magnet provided nearby, a hole is provided in the bottom or wall of the case opposite to the fixed contact so that the permanent magnet can be fixed from the outside of the case. A DC circuit breaker characterized by:
しゃ断器において、穴はケース内へ貫通していないこと
を特徴とする直流回路用しゃ断器。(2) Scope of Utility Model Registration The DC circuit breaker according to claim 1, characterized in that the hole does not penetrate into the case.
