JLS020 - 20 Amp Fuse

JLS020 - 20 Amp Fuse

If you're replacing a 20A Class J fuse, matching the amperage is easy. The other specifications matter just as much. The JLS020 is a fast-acting industrial cartridge fuse rated for 20 amps and up to 600VAC, with a 200 kA interrupting rating at 600VAC. In other words, this is a very specific 20A fuse—not simply any fuse carrying a 20A rating. Check the class, voltage, interrupting rating, opening characteristic, physical format, and holder requirements against your equipment before matching.
