UL Class J Time-Delay Fuses for Tight Spaces
Knife-Blade Style 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.
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.
Fuses with blown fuse indicator have a dot on the side that changes color when the fuse blows.
