Abstract: A dual element ferrule fuse includes a short circuit element and an overload element. The overload element includes a heater element which, in addition to carrying heat, is designed to partially enclose the overload element with tabs that provide a weldable surface between the element and the metallic end cap, thus eliminating the need for a separate washer. Additionally, the tabs serve to center the element in the end cap and retain the element at a certain point in the fuse body between assembly of the fuse and soldering of the cap to the weldable surface.
