ることを特徴とする限流ヒユーズ。 A ribbon-shaped fusible body with narrow portions distributed in the length direction is spirally wound around an internal insulating tube, and both ends of the fusible body are made of metal bands wrapped around both ends of the internal insulating tube. The retaining ring is connected to the retaining ring to form a fusible part, and the retaining ring and the conductive cap are connected to each other through a conductive member in an external insulating tube whose ends are covered with conductive caps and sealed. In the current limiting fuse, the fusible body is housed so as to be electrically connected to each other, and arc-extinguishing sand is filled between the housed fusible part and the external insulating tube, and both ends of the fusible body are A current limiting fuse, characterized in that the current limiting fuse is connected to the retaining ring via a conductor having a current carrying cross section larger than that of the current limiting fuse.
