Blade Fuses MICRO2 Blade Fuses Rated 32V The MICRO2 Fuse is the new standard for vehicle circuit protection. Its sub-miniature design meets the need for more circuits to be protected while utilizing less space and its ability to cope with high temperatures in adverse environments makes the MICRO2 Fuse of recommended choice for protection. Black amperage stamps are used on the 20A & 25A / light colored housings to improve contrast for vision system inspection.
