Claims (2)
- 入出力に対応した一対の端子部と、固定接点を有して一方の端子部に接続される固定端子板と、前記固定接点に接離する可動接点を有する可動接触子と、前記可動接触子と他方の端子部とを接続するリード線と、前記可動接触子が回動可能に取り付けられて共に回動するクロスバーと、互いに接触している固定接点と可動接点との間に過電流が流れた際に可動接触子を回動させて可動接点と固定接点とを強制的に離間させる過電流遮断手段とを内部に収納するケースを備える回路遮断器において、
前記リード線は、前記過電流遮断手段によってクロスバーが回動して可動接点が固定接点から離間する際に、クロスバー内で開極側へ回動している可動接触子を、張力によって開極側から閉極側へ反転させる力を付与することを特徴とする回路遮断器。 - 前記リード線は、可動接触子に接続される一端と、他方の端子部に接続される他端との間で調整板によって支持され、当該調整板によって前記張力が調整されることを特徴とする請求項1記載の回路遮断器。
