ABSTRACT:
A fuse link, especially for low voltage, high-breaking-capacity fuses, includes at least one fusible conductor having a soldering substance in a solder depot of a carrier, the solder being tin-based and the carrier being copper-based. The solder contains a tin alloy as an active substance, the tin alloy having two other constituents. The first constituent, which is the larger of the two in weight percent but which is smaller in weight percent than the proportion of the base substance tin, is selected for lowering the fusion temperature of the solder. The second constituent, which is the smaller of the two in weight percent, is a substance which does not dissolve in tin. Crystal nuclei are formed when said substance is cooled from the liquid state to the solid state, creating a fine structure and preventing the structure from becoming coarse under a load.
