Claims (4)
- 複数の電路を有して、個々の電路にバイメタル片を備えて熱動形或いは熱動電磁形の引き外し構造を具備し、前記バイメタル片が過電流発生を受けて掛合する掛合片とのギャップを調整ねじにより調整可能とした回路遮断器のバイメタル調整構造であって、前記バイメタル片は先端側に接続した第1可撓導線と基端側に接続した第2可撓導線とで前記電路に介在して成り、前記バイメタル片を支持板に固着して該支持板に前記調整ねじを螺入し、該調整ネジを移動しないように設けるとともに前記支持板を回転しないように設け、前記調整ねじの回転操作によって前記支持板を前記調整ねじの軸方向に移動させて前記ギャップを調整することを特徴とする回路遮断器のバイメタル調整構造。
- 前記調整ねじの軸方向に付勢してケースに押圧させる付勢バネ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のバイメタル調整構造。
- 前記支持板の上下一方をケースに押圧させる板バネを設けたことを特徴とする請求項1又は請求項2に記載の回路遮断器のバイメタル調整構造。
- 前記バイメタル片の移動時に接触して回転するコロを設けたことを特徴とする請求項1乃至請求項3の何れかに記載の回路遮断器のバイメタル調整構造。
