Class G Fuses

Littelfuse offers a broad range of industrial power fuses for protection of electrical circuits in a variety of applications. The Littelfuse Class G fuses are available in several different sizes depending on the ampere rating and are not interchangeable with any other UL fuse class. The fuse’s varying length prevents insertion of higher ampere rated fuses in fuse holders designed for lower ampere ratings. Littelfuse offers the Class G SLC series for use in branch circuit protection. These are time-delay, current-limiting fuses with an interrupting rating of 100 kA.
