プ機構と、このトリツプ機構がトリツプ動作する
ことによつて回動して接点を開く可動接点が固着
された複数の可動接触子と、接点の開閉操作及び
トリツプ機構がトリツプ動作した状態の解除を行
うハンドルと、トリツプ機構のトリツプ動作の解
除時にトリツプ機構と連動して上記複数の可動接
触子を同時に接点を閉じる方向に回動させる駆動
片とを備えた回路遮断器において、接点が閉じる
直前だけにいずれかの接点開閉機構部材に当接し
て接点の接触を遅らせる絶縁材製の当接部を夫々
の接点開閉機構部に設けた回路遮断器。 A trip mechanism that performs a trip operation when an overcurrent flows; a plurality of movable contacts having fixed movable contacts that rotate and open the contacts when the trip mechanism performs the trip operation; A handle for releasing the tripping operation of the tripping mechanism, and a drive piece for simultaneously rotating the plurality of movable contacts in the direction of closing the contacts in conjunction with the tripping mechanism when the tripping operation of the tripping mechanism is canceled. A circuit breaker in which each contact opening/closing mechanism is provided with a contact part made of an insulating material that comes into contact with one of the contact opening/closing mechanism members just before the contact closes, thereby delaying the contact of the contacts.
