Circuit breaker

Abstract

A second link constitutes another part of a toggle link in an open-close mechanism , has one end rotatably connected to a toggle pin and another end rotatably connected to a movable holder, and opens and closes a contact by causing the movable holder to rotate. A partition wall separates the open-close mechanism side and the movable holder side and has a slot for the second link. The second link is formed in an outer shape in which at a central portion of a path extending from one end to another end when viewed from a width direction, both an outline on a power supply side and an outline on a load side are drawn closer to a power supply side. The slot is set so that a gap is minimized within a range not causing interference with movement of the second link.
