Fast-Acting Glass-Tube Fuses

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.

Glass-Tube and Ceramic-Tube Fuse Assortments


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.
