About Fuses

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 RK5 Fuses

Ferrule Style with Blown-Fuse Indicator

Knife-Blade Style 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.

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

Ferrule Style

Knife-Blade Style with Blown-Fuse Indicator

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.

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 RK1 Time-Delay Fuses

Ferrule Style

Knife-Blade Style

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. They have a rejection-style end design that safeguards against replacement errors. Designed for use with Fuse Blocks for UL Class RK1 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.

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.

Time-Delay Plug Base Fuses

Type GSL and S

Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges, such as during equipment start-up. They are designed to fit into a socket on a panel; match the fuse to your panel socket by the manufacturer equivalent.

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.

Type GSL and S fuses have a non-interchangeable base to prevent the wrong size fuse from being used.

Long-Time-Delay Plug Base Fuses

These fuses have a longer time delay than standard time-delay fuses. Use them in motor applications where the motor is cycled on and off frequently. Also known as Edison-type fuses, they are designed to fit into a socket on a panel; match the fuse to your panel socket by the manufacturer equivalent.

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.
