What Is the Difference Between ATC & ATM Fuses?

by Jamie Peacock

A fuse is used in an electrical circuit. Its purpose is to either protect a source of power or protect the electronic equipment. Sometimes fuses need to be replaced. Knowing what kind to use is important.

Significance

Both ATC and ATM fuses are considered to be a blade or plug-in fuse. They have two prongs and are made with a plastic body. Plug-in fuses were created in 1976. They both use the same color-coded amp ratings that are universally employed.

ATC Fuse

ATC fuses were created before ATM fuses. An ATC fuse will be larger than an ATM fuse in physical size. This is considered to be the regular size. An ATC fuse will be found in late-model electronic devices.

ATM Fuse

An ATM fuse is considered to be a mini fuse and it came out in the early 1990s. The only difference is it is smaller than an ATC fuse in actual size. It generally cannot be used in a fuse block that is made for an ATC fuse, as it will not fit in properly.
