Blade Terminal & Special Purpose Fuses Low Voltage RoHS MAXI® Fuse Slo-Blo Type Fuse ® ® The MAXI Fuse is available in a higher range of amperage ratings (20–80 amperes) than the MINI® Fuse and ATO® Fuse designs and is larger in physical size. A typical MAXI Fuse application in today’s more sophisticated automobile circuits is protection of the wiring harness by replacing the fusible wire or fusible link, which is often a plain piece of small wire.
