UL Class J Time-Delay Fuses for Tight Spaces


Ferrule Cartridge Fuse, With Blown Fuse Indicator	Knife-Blade Cartridge Fuse, With Blown Fuse Indicator

Also known as dual-element fuses, these 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. More compact than UL Class RK1 or RK5 fuses, they are suitable for tight spaces. Use with Fuse Blocks for UL Class J Fuses.

With Blown Fuse Indicator—Fuses with blown fuse indicator have a dot on the side that changes color when the fuse blows.

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.

Time-Delay Ceramic-Tube Fuses

5mm Dia.

Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges. They can withstand temperature swings and high ambient temperatures better than glass-tube fuses. Use them with electronics, control panels, and other sensitive components. Select these fuses by their diameters. Designed for use with Fuse Blocks for Ceramic-Tube Fuses.

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.
