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 @ 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	Ferrule 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.

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.

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.

With Rejection-Style End—Fuses with a rejection-style end safeguard against replacement errors.

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.

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