About Blade types: 

Plug-in fuses (also called blade or spade fuses), with a plastic body and two prongs that fit into sockets, are mostl commonly used in automobiles, RV's and electronics. These types of fuses come in four different physical dimensions: mini (ATM or APM), low-profile mini, regular (ATO, ATC, or APR) and maxi (APX). 

We sell fuse plugs for the "mini" and "regular" types.

Additional Details:
