## 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.
