摘要： Embodiments of this application provide a circuit breaker and a power distribution system, and relate to the field of electrical device technologies. The circuit breaker includes a housing, a link mechanism, a movable contact plate, and a fixed contact plate that are disposed in the housing. The link mechanism is connected to the movable contact plate to control the movable contact plate and the fixed contact plate to switch between a switched-on state and a switched-off state. The link mechanism includes a fixing plate, a crank arm, a jumper subboard assembly, and a diversion plate. The crank arm is hinged to the fixing plate. The jumper subboard assembly is hinged to the crank arm. The diversion plate is separately hinged to the jumper subboard assembly, to the movable contact plate, and through a rotating shaft, to the fixing plate. A hinge joint between the diversion plate and the jumper subboard assembly, a hinge joint between the diversion plate and the movable contact plate, and a hinge joint between the diversion plate and the fixing plate are arranged in a triangular shape. The movable contact plate has a strip-shaped hole. A surface on which the movable contact plate and the fixed contact plate come into contact is a contact plane. An extension direction of the strip-shaped hole is not parallel to the contact plane. The rotating shaft passes through the strip-shaped hole, and the movable contact plate can move relative to the rotating shaft along the extension direction of the strip-shaped hole.
