About Fuses

5mm Dia.

Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges. They can withstand temperature swings and high ambient temperatures better than glass-tube fuses. Use them with electronics, control panels, and other sensitive components. Select these fuses by their diameters. Designed for use with Fuse Blocks for Ceramic-Tube 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.
