Melting conductor and fuse

A melting conductor for one or more of a DC fuse and a high-voltage high-power DC fuse (HH-DC fuse), wherein the melting conductor comprises:

• an electrically conductive melting wire, wherein the melting wire comprises at least two overload narrow sections, the at least two overload narrow sections being respective cross-sectional constrictions, wherein, between the at least two overload narrow sections in at least one first section, there is at least one first layer comprising solder which at least partially surrounds the outer shell surface of the melting wire circumferentially, wherein a second layer, which is a coating, surrounds the outer shell surface of the melting wire circumferentially, the second layer adjacent to each of the overload narrow sections in a respective second section, and wherein the melting wire further comprises between the at least two overload narrow sections at least one short circuit narrow section that is a cross-sectional constriction, wherein a rated minimum interrupting current of the fuse is between greater than 3 times a rated current of the fuse, and less than 8 times the rated current.
