UL Class RK1 Time-Delay Fuses


Ferrule Cartridge Fuse	Knife-Blade Cartridge Fuse

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. They have a rejection-style end design that safeguards against replacement errors. Designed for use with Fuse Blocks for UL Class RK1 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.
