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 a nonporous dielectric sheet covering the exposed surface of the clips and being interposed between and in contact with the clips and the main fusible element for determining the arc gap between them.
