An over current breaker is provided to prevent damage due to the arc, generated from the contact or separation of a movable contact and fixture contact, flying by guiding arc to upside through a bend runner. An overcurrent breaker for the cabinet panel comprises a movable contact(23), an open and close device part(13) and an operation lever(21). The contact point of the movable contact is switched to an input side terminal(16) and a load side terminal(17). A bimetal(19) pulls back the operation lever, and the operation lever operates the open and close device part. The bend runner(24) is fixed to the leading end of the movable contact into one body. A projection is formed on the top of the contact point of the movable contact and it passes through the bend runner and movable contact.
