Generally, two sizes of user-replaceable fuses are found: the 1/4” x 1-1/4” and 5×20 mm. Each is available in a variety of volt and amp ratings. There are two basic types of fuses available for appliances and consumer electronics: fast-acting or time-delay.
How many sizes of fuses are there?
There are 4 main types of fuses: Micro, Mini (APM, ATM), Standard (APR, ATC, ATO), and Maxi (APX). Each fuse can be color coded with the appropriate amperage rating on top.
How do I know what size fuses to use?
B Calculate MINIMUM FUSE AMPERAGE by multiplying product amperage rating by 125%. Minimum fuse amperage provides more protection for the wire but may result in nuisance blows. Example: 80A x 125% = 100A. C Choose FUSE AMPERAGE near the middle of this range.
