ないようにしたことを特徴とする回路遮断器。[Claims for Utility Model Registration] A stator having a fixed contact, a movable element having a movable contact facing the fixed contact, a toggle link mechanism for opening and closing the movable element, and a tri-platform operated by an automatic tripping mechanism. and a trip lever that engages with the trip latch and disengages from the trip latch when the automatic tripping mechanism is activated to open the mover via the toggle link mechanism. A circuit breaker comprising: a cam portion; the cam portion pushes down the mover to extend the toggle link mechanism during reset, thereby preventing the trip latch from contacting the toggle link mechanism.
