ABSTRACT:
The fuse is of the general purpose type having a casing closed at the ends by terminal caps; a core inside the casing; a main fusible element wound about the core and connected between the caps; a pair of arcing clips mounted in spaced relation on the core adjacent the main fusible element; and, an auxiliary element also wound about the core and connecting together the arcing clips. The improvement comprises that segments of the main element passing over the arcing clips are provided with additional reduced cross-sectional necks for improving the melting response of the element upon arcing between the element and the clips.
