回路しや断器。 A fixed contact fixed to a fixed contact, a movable contact that comes into contact with and separates from the fixed contact, a movable contact fixed to one end and rotatable, and an arc generated between both movable fixed contacts. A side plate of the arc extinguisher is provided in a circuit or disconnector which has an arc extinguisher that drives the arc extinguisher in a predetermined direction, and operates a movable contact via a link mechanism by an external force applied to a handle to open and close the contact. A translucent reflector plate is attached to the inner surface of the base plate, a slit is provided in the side plate at a position less than 45 degrees from the contact position, and a light receiving plate is provided to detect the arc light passing through this slit. A circuit breaker is provided and is tripped by the output of the light receiving plate.
