Abstract
A high voltage high power fuse (5) for use in a low pressure environment such as space. The fuse (5) comprises a fuse element (1) which is electrically connected to two conductive pads (2) and surrounded by an elastic medium (3). When the fuse element (1) is vaporized by a current surge, the elastic medium (3) absorbs the energy of the explosion and then snaps back into the space (6) left by the vaporized fuse element (1). This action of the elastic medium (3) effectively quenches any electric arc which may have bridged the gap (6) between the ends of the blown fuse element (1).
