構成した回路しゃ断器。(1) At least one of a pair of electrical contacts consisting of a conductor and a contact fixed to the conductor is provided with a protrusion made of a material having substantially the same conductivity as the conductor and in contact with the conductor; A reaction force reflector made of a high-resistance material with higher resistivity than the conductor is placed on the conductor of the contact so as to surround the outer periphery of the contact, and is used to extinguish the arc that occurs between the contacts. The arc-extinguishing plate is provided with a cutout groove whose one end is open to the contact side, and the protrusion is made to protrude above the pressure reflector, and the surface area of the protrusion is reduced to the contactor on which the protrusion is provided. A circuit breaker configured with a surface area smaller than the surface area of the contacts.
案登録請求の範囲第1項記載の回路しゃ断器。(2) The circuit breaker according to claim 1, wherein the arc-extinguishing plate is made of a magnetic material or a non-magnetic material.
らアークの走行方向へ向って延び、突起部があるときは
この突起部まで達する溝を設けて、導体の表面を露出さ
せた実用新案登録請求の範囲第11または第2項記載の
回路しゃ断器。(3) A utility model in which the pressure reflector is provided with a groove that starts from one side of the contact and extends in the direction of travel of the arc, reaching as far as the protrusion if there is a protrusion, thereby exposing the surface of the conductor. A circuit breaker according to registered claim 11 or 2.
