Claims

[Scope of utility model registration request]

a contact plate that holds a power supply side movable contact and a load side movable contact at both ends of one pole; a power supply side contact block that holds a power supply side fixed contact that the power supply side movable contact of the contact plate contacts and releases;
A load-side contact block that holds a load-side fixed contact that is contacted and opened by the load-side movable contact of the contact plate, an overcurrent tripping device electrically connected to the load-side contact block, and this overcurrent tripping device. A switching device that causes the contact plate to open in conjunction with the operation when an overcurrent is applied to the device; a support member connected to the switching device and configured to be movable up and down; and a support member that allows the contact plate to be moved upwardly. a contact elastic body that presses the support member from below; a return elastic body that presses the support member from below; an arc extinguishing device disposed near the movable contact on the power source side; and an arc extinguishing device disposed above the arc extinguishing device. When the contact plate is opened, the support member first lifts up the part of the contact plate located on the power supply side from the contact part with the contact pressure elastic body, and then contacts the part located on the load side. A circuit breaker for wiring, characterized in that the contact plate is configured to be lifted up.
