and an overload fuse element having a first end mechanically and electrically connected to the first terminal element and a second end mechanically and electrically connected to the second terminal element, wherein the overload fuse element is configured to be uniquely responsive to interrupt a low overcurrent or overload fault current condition in the electrical power system; wherein the short circuit fuse element and the overload fuse element are identically formed fusible elements including a plurality of co-planar sections separated by a plurality of oblique sections (242, 244), the short circuit fuse element and the overload fuse element arranged in the housing as mirror images of one another; and wherein the short circuit fuse element and the overload fuse element are operable in combination to safely interrupt the high current or short circuit fault and the low overcurrent or overload fault current with equal effectiveness; an arc extinguishing filler in the housing, wherein the arc extinguishing filler is mechanically bonded to at least a portion of the short circuit fuse element and the overload fuse element and also a portion of the first and second terminal elements; and an arc barrier material, separate from the filler, surrounding each of the short circuit fuse element and the overload fuse element at a location proximate the respective first and second terminals. a housing;
