れた回路遮断器。[Claims for Utility Model Registration] (1) A circuit breaker in which a reversing spring is interposed between a cradle latched to a trip link and a movable contact, and the movable contact is pivotally supported on a handle, which has a terminal. A frame is attached to the body, the frame supports the tripping link and the handle, a cut-and-raised piece for supporting the cradle is formed on the frame, and a bearing portion of the cradle is pivotally supported by the cut-and-raised piece. circuit breaker. (2) a body having a terminal; a frame formed with a cut-and-raised piece for supporting the cradle; and a frame attached to the body; and a handle having a connecting shaft and being pivotally supported by the frame by a first fixed shaft. a movable contact having a movable contact and a first spring support on the rotating side and pivotally supported on the connecting shaft; and a movable contact disposed opposite to the movable contact and caused by the operation of the movable contact. a fixed contact that connects and separates; a reversing spring that has one end attached to the first spring support portion of the movable contact; and a hook receiving portion that is attached to the frame and that responds to abnormal current detection means. the spring force of the reversing spring; and a cradle having a hook part that is hooked on the hook receiving part of the tripping link, and when the hook part is hooked on the tripping link, the handle is operated to the on position and the off position. The connecting shaft rotates so that the line of action connecting the first spring support part and the connecting shaft crosses the second spring support part, and the tripping link is activated by the operation of the abnormal current detecting means. When the hook is operated and the hook is disengaged from the hook receiver of the tripping link, the cradle rotates and the second spring support crosses the line of action.
A circuit breaker in which a positional relationship between a spring support portion and the line of action is set.
