High-current fuse with endbell assembly

A fuse includes a fuse element and a fuse body. A portion of the fuse element is housed in a fuse body. The fuse element includes a first terminal and a second terminal disposed outside of the fuse body. The first terminal and the second terminal electrically connects the fuse element to a circuit to be protected and a power source. A first endbell and a second endbell is coupled to the fuse element. A predetermined amount of arc quenching material is disposed within the fuse body. The arc quenching material contacts at least a portion of the fuse element. The predetermined amount of the arc quenching material is less than a total volume size of the fuse tube. The arc quenching material is compacted. A remaining air gap in the fuse tube is filled with a liquid adhesive and cured to a solid state.
