Fast-Acting Ceramic-Tube Fuses

1/4" 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.

1/4" Overall Diameter—_1/4" dia. fuses can be used in high-current electronic circuits such as microwave ovens.

Breakthrough Current @ Voltage—Breakthrough current at voltage, labeled on the fuse as IR, is the maximum current that a fuse can safely stop in the event of a short circuit.

140 Pieces	270 Pieces

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

3AB Ceramic-Tube Fast-Acting and Time-Delay Fuses, 3AG Glass-Tube 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.

5mm Dia. Glass-Tube Fast-Acting Fuses—Fast-acting fuses open circuits quickly when surges are detected so they are suitable for resistive loads that do not have temporary overload current.
