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, 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.
