Claims (2)

  1. 과전류에 의한 바이메탈의 변위를 전달하는 시프터와, 이 시프터에 일단이 결합하고 바이메탈의 변위에 의해 시프터를 거쳐서 회동되는 석방 레버와, 이 석방레버에 연결됨과 동시에 회동이 자유롭게 받쳐지고 조정 다이얼의 캠에 압압된 조정링과, 상기 석방 레버가 결합하는 인장 스프링에 연결되어 석방레버의 회동에 따른 인장스프링의 작용선이 사점을 초과하면 반전하는 가동판과, 이 가동판의 반전에 의해 접촉 분리하는 서로 절연된 통상 개방, 통상 폐쇄의 최소한 1쌍 이상으로 이루어지는 접점장치를 구비한 열형 과부하 계전기에 있어서, 상기 가동판을 절연재료의 성형품으로 구성한 것을 특징으로 하는 열형 과부하 계전기.
  2. 제1항 기재의 열형 과부하 계전기에 있어서, 가동판에 동작 표시부를 연재시켜서 설치한 것을 특징으로 하는 열형 과부하 계전기.
