路しや断器。 The circuit breaker is designed to perform current limiting by separating the movable element by electromagnetic repulsion due to the application of a large current, regardless of the breaker operation by an automatic tripping device, and the movable contact of the movable element a fixed conductor having a fixed contact that comes into contact with and separates from the movable element; a contact arm that holds the movable element; a pin that rotatably pivots the movable element to the contact arm; and a flexible conductor that is connected to the movable element. In the circuit breaker and disconnector, an extension part formed by bending and extending in the direction of the fixed conductor is provided on the flexible conductor connection side of the movable element, and the pin is arranged closer to the extension part than the movable contact. A circuit breaker characterized by being located at.
