摘要： In order to prevent a mistrip caused by a closing operation of a toggle link mechanism, a trip lever is not mounted on a fixed frame of an opening/closing mechanism, but is mounted on a yoke of a disengaging device serving as a support base for the trip lever. The opening/closing mechanism and the disengaging device are held in a common casing. As a result, an impact force, produced at the time of closing the contact between two contacts by the toggle link mechanism, is transmitted through the casing, so that such a mistrip can be prevented.
