Abstract
The invention relates to an use of a melting conductor (1) for a DC fuse (2) and a high-voltage high-power fuse (2) (HH-DC fuse), wherein the melting conductor (1) comprises an electrically conductive melting wire (3), wherein the melting wire (3) comprises at least two overload narrow sections (4) in the form of a cross-sectional constriction, wherein, preferably between the two immediately successive overload narrow sections (4) a first layer (7) comprising solder and/or surrounding the outer shell surface (6) of the melting wire (3) circumferentially at least in some areas, preferably completely, is provided in at least one first section (5), and wherein a second layer (9) surrounding the outer shell surface (6) of the melting wire (3) circumferentially at least in some areas, preferably completely, is provided adjacent to each of the overload narrow sections (4) in a respective second section (8).
