About Fuses

Ferrule Style

Knife-Blade Style

Replace the current-carrying element rather than the entire fuse after the fuse breaks. Use with Fuse Blocks for UL Class H Fuses.

Breakthrough current, labeled on the fuse as IR, is the maximum current that a fuse can safely stop in the event of a short circuit.
