UL Class J Fast-Acting Fuses for Tight Spaces
Ferrule Style
These fuses open circuits quickly when surges are detected. 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.
