To provide a current shut-off system that can further safely disconnect wiring of a battery using a pyro-switch.SOLUTION: A current shut-off system includes: a shunt resistor 100 for measuring a current value flowing to a motor M from a battery B; a threshold detection unit 10 for detecting whether the current value measured by the shunt resistor 100 exceeds a preset threshold; and a pyro-switch 200 for disconnecting the shunt resistor 100 when the threshold detection unit 10 detects that the current value exceeds the preset threshold.SELECTED DRAWING: Figure 1

    【課題】パイロスイッチを用いて、バッテリの配線をより安全に切断することができる電流遮断システムを提供する。【解決手段】バッテリBからモータMへ流れる電流値を計測するシャント抵抗器100と、シャント抵抗器100にて計測された電流値が予め設定された閾値を超えた否かを検出する閾値検出部10と、閾値検出部10が、閾値を超えたことを検出すると、シャント抵抗器100を切断するパイロスイッチ200と、を有してなる。【選択図】図1
