回路しや断器。[Claims for Utility Model Registration] (1) A first contact connected to the opening/closing mechanism, a second contact opposite thereto, an external connection terminal electrically connected to the second contact, an arc extinguishing chamber for extinguishing an arc generated between the first contact and the second contact; and a first arc extinguishing chamber disposed between the arc extinguishing chamber and the external connection terminal and having an exhaust hole. In a circuit or disconnector equipped with a perforated insulating partition, a second perforated insulating partition having an exhaust hole is provided adjacent to at least one side of the first perforated insulating partition, and the second perforated insulating partition is adjacent to the first perforated insulating partition. A circuit switch or disconnector characterized in that the exhaust holes of the perforated insulating partition wall are shifted so that they do not overlap with each other. (2) Claims for registration of a utility model characterized in that the first and second perforated insulating partition walls are each constructed of the same perforated insulating partition wall with exhaust holes arranged asymmetrically with respect to its vertical or horizontal center line. The circuit breaker described in paragraph 1.
