UL Class CC Time-Delay Midget Fuses for Motors

These fuses can withstand the high inrush current caused by a motor starting. They provide comparable performance with a smaller footprint than standard size fuses. All have a rejection-style end that safeguards against replacement errors. Use them to protect power distribution branch circuits. Designed for use with Fuse Blocks for UL Class CC 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.

UL Class CC Time-Delay Midget Fuses for Transformers

Designed to handle high inrush currents and the initial current cycle unique to transformers, these fuses provide comparable performance with a smaller footprint than standard size fuses. Use them to protect power distribution branch circuits. They’re for use with Fuse Blocks for UL Class CC Fuses.
Fuses with a rejection-style end safeguard against replacement errors.

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 J Time-Delay Fuses for Tight Spaces

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. More compact than UL Class RK1 or RK5 fuses, they are suitable for tight spaces. Use with Fuse Blocks for UL Class J Fuses.

Touch-Safe Fuses

Prevent accidental contact with electrical circuits—these fuses have an enclosed design with recessed plug-in blades. Also known as dual-element fuses, they withstand current overload for a short time so they won't open when exposed to harmless temporary surges, such as when starting a motor.
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 turns red when the fuse blows.
