Claims

[Claims for Utility Model Registration] A first conductive plate having an opening for a handle and having a fixed contact provided at one end, and a second conductive plate having an overcurrent sensor provided at one end, each having an opening at the other end. a case mounted so that it is exposed; a contact holding plate formed of a magnetic material into a substantially U-shape and fixed near the handle opening of the case; and a movable contact, the movable contact being a fixed contact. A movable contact is rotatably supported on a contact holding plate so as to move toward and away from the contact, and an armature is positioned so that it can be attracted to the contact holding plate, and when it is attracted, both The handle is supported by the case so that it can freely rotate from the contact closed position to the contact open position so that a magnetic path is formed at Here, a reversing spring is suspended between the handle and the movable contact so as to apply a contact pressure to the movable contact and a separation force to the movable contact at the contact open position side, an overcurrent sensor, and a movable contact. and an electrically connected electrical circuit section, the drive section of the overcurrent sensor is arranged so as to drive the handle to a position beyond approximately the midpoint of the rotation section when an overcurrent flows, and the electrical circuit section , a circuit breaker arranged to pass through a magnetic path formed by a contact holding plate and an armature, wherein the movable contact is driven in the direction of separation from the armature when the movable contact is separated from the fixed contact. A circuit breaker characterized by forming a passive part that receives force.
