Claims (4)

제1의 구출단자를 보유하고 또한 대 전류가 흐른 경우에 예정시간의 지체로써 잡아빼기 동작하는 단한시형의 과전류 잡아빼기 장치를 보유한 차단기 본체부와 제2의 구출단자가 설치되고, 또한 한류차단부 고정접점이 설치된 한류차단부 고정도체와 상기 차단기 본체부와 전기적으로 접속되고 또한 상기 한류차단부 고정접점과 대응하여서 한류차단부 가동접점이 설치되고 또한 이 한류차단부 가동접점과 상기 한류차단부 고정 접점이 폐로상태에서는 상기 한류차단부 고정도체에 대하여서 역방향으로 통전로가 형성되는 것과 같이 상기 한류차단부 고정도체와 동시에 평행도체를 형성하는 회동가능한 한류차단부 가동 접촉자와로되는 회로차단기에 있어서, 한류차단부 고정도체에 있어서의 상기 한류차단부 고정접점과 상기 제2의 구출단자와가 설치된 위치에 대한 중간부위에 설치된 고정철심과 이 고정철심과 동시에 전자석부를 구성하는 것으로서 상기 고정철심에 대응한 한류차단 가동접촉자의 소정의 위치에 설치되고, 또한 한류차단부 고정도체에 대전류가 흐르고, 상기 고정철심이 여자되면 상기 한류차단부고정접점 및 한류차단부 가동접점을 개로시키도록 흡인 동작하는 가동철심과를 구비한 것을 특징으로 하는 회로차단기.A breaker main body and a second rescue terminal are provided which have a first rescue terminal and a short time overcurrent pull-out device which is pulled out as a delay of a predetermined time when a large current flows. The current-limiting current-carrying part of the current-limiting circuit is electrically connected to the current-limiting circuit of the current-limiting circuit and the circuit breaker main body. In a circuit breaker comprising a rotatable current-limiting part movable contactor which forms a parallel conductor at the same time as the current-limiting part high-conductor, such that current flow paths are formed in a reverse direction with respect to the current-limiting part high-conductor when the contact is closed. The current-limiting breaker fixed contact and the second rescue terminal in the current-limiting high-conductor The fixed iron core installed at the middle part with respect to the fixed position and the electromagnet portion simultaneously with the fixed iron core are installed at a predetermined position of the current-limiting movable contactor corresponding to the fixed iron core, and a large current flows through the high-limiting current-limiting conductor. And a movable core formed by suction to open the current blocking portion fixed contact and the current blocking portion movable contact when the fixed iron core is excited. 제1항에 있어서, 가동철심은 상기 한류차단부 가동접촉자의 회동중심에 대해 회동모멘트가 최소로되는 위치에 설치한 것을 특징으로 하는 회로차단기.The circuit breaker according to claim 1, wherein the movable iron core is provided at a position where the rotation moment is minimum with respect to the center of rotation of the movable contact of the current-limiting breaker. 제1항에 있어서, 전자 석부는 한류차단부 고정접점 및 한류 차단부 가동 접점에 비여자시에는 접촉압력을 부여함과 동시에 여자시에는 개리동작을 늦어지도록 기능하는 스프링을 보유한 것을 특징으로 하는 회로 차단기.The circuit according to claim 1, wherein the electromagnet has a spring which functions to impart a contact pressure to the current-limiting part fixed contact point and the current-limiting breaker movable contact when it is not excited and to delay the opening operation when the part is excited. breaker. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
