Claims (1)
- 配線用遮断器において、
前記配線用遮断器の下部室に位置する複数の主回路部であって、各前記主回路部は固定接触子及び前記固定接触子に接離する位置に回動可能な可動接触子を備えて回路を開閉する主回路部と、
前記配線用遮断器の上部室に位置し、前記主回路部に接続されて、前記主回路部が回路を開放するように前記主回路部を駆動する開放駆動位置、及び前記主回路部が閉回路を形成するように前記主回路部を駆動する閉路駆動位置を有する開閉機構と、
前記上部室に位置し、回路の異常電流の発生による電磁吸引力により作動して前記開閉機構が前記開放駆動位置に動作するようにトリガする機械的瞬時トリップメカニズムと、
前記主回路部が位置する前記下部室と前記瞬時トリップメカニズム及び前記開閉機構が位置する前記上部室とを分離して電気的に絶縁するように、前記上部室と前記下部室との間に前記複数の主回路部に共通に設けられる絶縁隔壁と
を含み、
前記開閉機構は、
拘束位置及び解放位置を有するラッチと、
前記ラッチを拘束する位置と前記ラッチを解放する位置とに回動可能なラッチホルダーと、
前記ラッチホルダーを加圧して回動させることができる位置に設置され、前記ラッチホルダーを加圧して前記ラッチを解放する位置に回動させるネールとを含み、
前記瞬時トリップメカニズムは、
前記主回路部の電気的導体部と対向するように離隔して設置され、強磁性体で構成され、前記導体部に異常電流が流れると前記導体部により吸引されて回動するアーマチュアと、
前記アーマチュアに弾性力を与えるように接触して設置され、前記導体部に正常電流が通電すれば、前記アーマチュアを元の位置に復帰させ、瞬時トリップ電流の通電により前記アーマチュアが回動すれば、前記アーマチュアの回動力より小さな予め定められた弾性力を前記アーマチュアに与える瞬時スプリングと、
前記アーマチュアにより加圧されて回動し、回動時に前記ネールを加圧して回動させることができるように前記ネール側に延びる延長部を有するクロスバーとを含み、
前記アーマチュアは、薄く長い板スプリングで構成される回動片を有し、
前記絶縁隔壁は、前記配線用遮断器の一部であり、上部ケースと一体に形成されることを特徴とする配線用遮断器。
