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.
