Abstract

A fuse link including a fuse element of known cross-sec­ tional area having a number of holes centrally located therein to define reduced cross-sectional areas and a filler material provided in said holes, said embodiment having a short time-current melt characteristic at high overload substantially the same as the homogeneous fuse element and a long time-current melt characteristic different from the long time-current melt characteristic of the fuse element.
