About Fuses

5mm Dia.

Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges. The clear glass tube makes it easy to see when fuses open. Use them with electronics, control panels, and other sensitive components. Select these fuses by their diameters. Designed for use with Fuse Blocks for Glass-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.

Touch-Safe Fuses

Prevent accidental contact with electrical circuits—these fuses have an enclosed design with recessed plug-in blades. Also known as dual-element fuses, they withstand current overload for a short time so they won't open when exposed to harmless temporary surges, such as when starting a motor.

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.

Fuses with blown fuse indicator have a dot on the side that turns red when the fuse blows.
