    Knife-Blade

    Cartridge Fuse

    Smaller than UL Class J fuses, these fast-acting fuses can be used in extra-tight spaces such as meters, uninterruptible power supplies, and variable-speed drives. They open circuits quickly when surges are detected. Use with Fuse Blocks for UL Class T 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 RK5 Fuses

    Ferrule Cartridge

    Fuse, With 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.
    With Blown Fuse Indicator—Fuses with blown fuse indicator have a dot on the side that changes color when the fuse blows.
    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.
