Claims (2)
- 장착면에 대하여 고정되는 하우징과,
도전 재료로 이루어지고, 상기 하우징에 보지되어 상기 하우징 내에 고정 접점을 보지하는 단자판과,
상기 하우징에 수납되어 상기 고정 접점에 이접 가능한 가동 접점과,
이상을 검출하여 상기 가동 접점을 상기 고정 접점으로부터 떼어 놓는 트립 장치를 구비하고,
상기 단자판은 상기 하우징 외부로 노출되어 전선이 접촉 도통하는 단자부와, 상기 하우징 내에 고정 접점을 보지하는 접점 보지부와, 상기 단자부와 상기 접점 보지부 사이에 개재하는 연결부를 갖고,
상기 연결부로부터의 상기 접점 보지부의 돌출 방향은 상기 전선을 통해 상기 단자부를 타고 물이 침투하는 방향의 반대 방향이고,
상기 접점 보지부는 상기 하우징 외부로 노출된 단자부보다 상기 장착면측에 배치되어 있으며,
상기 하우징에는, 상기 하우징 외부의 공간과 상기 하우징 내에 있어서 상기 고정 접점이 수납된 공간을 서로 연통시키는 통기 구멍이 마련되어 있고,
상기 통기 구멍은, 상기 하우징 외부로 노출된 단자부보다 또한 상기 접점 보지부보다 상기 장착면측에 배치되어 있는 것을 특징으로 하는
회로 차단기. - 제 1 항에 있어서,
상기 통기 구멍은 상방에서 보아 상기 고정 접점을 노출시키지 않는 위치에 마련되어 있는 것을 특징으로 하는
회로 차단기.
