Abstract
A fuse for a high voltage/high current application, such as a hydro-electric vehicle ('HEV') application is provided. The fuse employs a variety of arc quenching features to handle a large amount of arcing energy that is generated when such fuse is opened due to a fuse opening event. In one embodiment, an insulative substrate, such as a melamine substrate, is metallized with a fuse element. The fuse element extends to multiple surfaces of the substrate. A fuse opening portion of the element is located so that the arcing energy is forced to travel along multiple insulative planes, increasing an impedance across the opening of the element and decreasing the likelihood of a sustained arc. Also, the substrate and element are disposed in a sealed housing, which is packed in one embodiment with an arc quenching material, such as sand.
