CARTRIDGE-TYPE FUSE AND FUSE ELEMENT THEREFOR

摘要

Case 2531 CARTRIDGE-TYPE FUSE AND FUSE ELEMENT THEREFOR A fuse element for a high voltage, current limiting fuse is made of a ribbon of metallic fusable material with holes punched at intervals along the length of the ribbon to provide regions of reduced cross-section, The holes are offset alternately to one side and the other side of the center of the ribbon creating on one side of the hole a smaller cross-sectional area than on the other side of said hole which appears to cause melting under fault current of the smaller cross-section first.
