Abstract
A fuse assembly for an electrical cutout is provided with capability for rapid arc extinction by a capsule of pressurized insulating gas being located within a fuse tube above the fusible element so that when the fusible element melts and an arc is produced, gas is released from the gas cylinder that quenches and cools the arc and also assists a spring loaded flipper mechanism in expelling a lower conductor from the fuse tube.
