About Fuses

1/4" Dia.

5mm Dia.

These fuses open circuits quickly when surges are detected. They can withstand temperature swings and high ambient temperatures better than glass-tube fuses. Use 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.

1/4" dia. fuses can be used in high-current electronic circuits such as microwave ovens.
