摘要： A fuse is provided for protection of high current power distribution equipment, such as transformers. The fuse includes a dual function fuse element having a solder pot which permits fuse opening in response to long-term current overload conditions, and a minimum cross-section wire portion for short circuit opening. The fuse element is enclosed within a tube, and the tube is received within a housing. The tube is closed off on one end thereof with a dual size button, which size is selectable for reception into the housing.
