    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.
