20-Amp Time Delay TCF Cube Fuse TCF20

The Cooper Bussmann CUBE Fuse is the world's first finger-safe power fuse. The Class CF CUBE Fuse has UL/CSA Class CF and Class J electrical performance with a current-limiting feature that minimizes incident energy to reduce arc-flash hazards to their lowest possible levels. High 300kA interrupting rating and 600Vac voltage rating (100kA/300Vdc) helps keep you protected even if available fault current levels should increase. The compact dovetailing design allows mixing and matching 30A, 60A and 100A holders into small 1-, 2- or 3-pole assemblies that take considerably less space than any other Class J fuse solution.
