UL Class J Time-Delay Fuses for Tight Spaces


Ferrule Cartridge Fuse, With Blown Fuse Indicator	Ferrule Cartridge Fuse, Without Blown Fuse Indicator

Knife-Blade Cartridge Fuse, With Blown Fuse Indicator	Knife-Blade Cartridge Fuse, Without 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.
