ABSTRACT:
An electric fuse has an undulated fusible element provided with a plurality of aligned, spaced perforations. A straight rod preferably of a gas-evolving material extends through said plurality of perforations. The rod increases significantly the dimensional stability of the fusible element structure and contributes at the same time significantly to arc-extinction, if made of a gas-evolving material.
