UL Class RK5 Fuses


Ferrule Cartridge Fuse, Without Blown Fuse Indicator	Knife-Blade Cartridge Fuse, Without Blown Fuse Indicator

Also known as dual-element fuses, these time-delay 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. They have a rejection-style end design that safeguards against replacement errors. Use with Fuse Blocks for UL Class RK5 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.

UL Class J Fast-Acting Fuses for Tight Spaces


Ferrule Cartridge Fuse	Knife-Blade Cartridge Fuse

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 @ 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.
