Claims

[Claims for Utility Model Registration] (1) An operating handle, a drive mechanism that can control opening and closing of a fixed contact and a movable contact in conjunction with the operating handle, and opening and closing of both of the contacts. The arc runner has an arc runner that guides the arc that is generated during the arc to the arc extinguishing chamber, and a bimetal fixed to a predetermined part of the arc runner, and the drive mechanism can be operated to open both of the contacts in the event of an overcurrent. bimetal mechanism, connection terminal to external circuit,
An adjusting device for adjusting the distance between the arc runner and the connection terminal near a predetermined location of the arc runner, wherein a protrusion is formed at another location of the arc runner and a portion of the connection terminal is adjusted. A circuit breaker characterized in that an L-shaped bent portion is formed by cutting and raising the protruding portion and the protruding portion is fixed to an inner surface of the L-shaped bent portion. (2) The circuit breaker according to claim 1 of the utility model registration, characterized in that the protruding portions formed on the arc runner protrude from both sides of the arc runner so as to form a cross shape. . (3) The circuit breaker according to claim 1 or 2, wherein the L-shaped bent portions are formed on both sides of the connection terminal.
