Abstract
An electric circuit cut-off device including a housing, a to-be-cut part, a power source, and a moving body that moves between first and second end portions on opposite sides, a fuse including a fusing portion and an arc-extinguishing material, and a pair of electrode parts connected to terminals on both sides of the fuse. The moving body is configured to cut a piece located between base pieces on both sides of the to-be-cut part and a part of the to-be-cut part and the electrode part come into contact with each other in a state where base pieces on both sides of the to-be-cut part are energized via the cut piece, and the to-be-cut part and the fuse are connected to each other; and thereafter a state in which the base pieces on both sides of the to-be-cut part are energized via the cut piece is cut off.
