About Fuses

0.18" Dia.

These fuses open circuits quickly when surges are detected. The clear glass tube makes it easy to see when fuses open. Use them with electronics, control panels, and other sensitive components. Select them by their diameter. 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.

Time-Delay Glass-Tube Fuses

0.18" 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.
