Claims (2)
- 電路と接続する端子と、該端子に接続される固定子片及び可動子片を備えるとともに、可動子片の先端の接点が固定子片の先端の接点と接離して開極及び閉極する駆動手段を備え、当該駆動手段は器枠長手方向前後の可動枠と引き外し枠と器枠中央上部のスナップ機構を備えた回路遮断器において、
前記端子と前記固定子片との接続位置付近にバイメタルの基端を固定し、該バイメタルを引き外し枠の短手方向両側に沿って立ち上げ、当該バイメタルの温度変形にともなう先端部の変移を利用して引き外し枠を、接点が開極する方向に回動させ、閉極した接点を開極するとともに、前記引き外し枠の短手方向両側に設けたバイメタルの遮熱ケースにアーク飛散用の永久磁石片を嵌め込んだことを特徴とする回路遮断器。 - 前記引き外し枠の側または前記バイメタルの側に、該引き外し枠と変形前の該バイメタルとの離間距離を調整する回路遮断温度設定部材を設けたことを特徴とする請求項1に記載の回路遮断器。
