Abstract
A wide-range current limiting fuse assembly particularly adapted to protect capacitors. The device comprises a current limiting portion having a corrugated fusible ribbon for high fault current protection, and a low current portion having a fusible link surrounded end to end by a conductive metal sleeve connected to one terminal of the fusible link. The current limiting portion may, alternatively, be provided with a circularly cross sectioned fusible wire connected in series with the fusible ribbon.
