About Fuses

1/4" Dia.

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.

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

Glass-Tube and Ceramic-Tube Fuse Assortments

140-Fuse Kit

270-Fuse Kit

Maintain a supply of fast-acting and time-delay fuses.

Time-delay fuses withstand current overload for a short time so they won’t open when exposed to harmless temporary surges, such as when starting a motor.

Fast-acting fuses open circuits quickly when surges are detected so they are suitable for resistive loads that do not have temporary overload current.
