UL Class RK5 Fuses

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.

UL Class T Fuses for Extra-Tight Spaces


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, also known as interrupt current, is the maximum current that a fuse can safely stop in the event of a short circuit.
