About Fuses

UL Class CC Time-Delay
Midget Fuses for Motors

These fuses can withstand the high inrush current caused by a motor starting.

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.

UL Class CC Fast-Acting
Midget Fuses

These fuses open circuits quickly when surges are detected.

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.

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.

UL Class J Fast-Acting
Fuses for Tight Spaces

These fuses open circuits quickly when surges are detected.

UL Class G Time-Delay Midget Fuses

Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges, such as when starting a motor.

UL Class RK1 Fast-Acting Fuses

These fuses open circuits quickly when surges are detected.

UL Class K5 Fuses

Use these fast-acting fuses in applications where temporary overload current is not present, such as in lighting and heating.

UL Class G Fast-Acting Midget Fuses

These fuses open circuits quickly when surges are detected.

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.

UL Class L High-Current Fuses

These time-delay fuses are suitable for high-current power applications.

UL Class H
Replaceable-Element Fuses

Replace the current-carrying element rather than the entire fuse after the fuse breaks. These fuses are fast-acting.

UL Class RK1 Time-Delay Fuses

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.

H Replaceable-Element Fuses

Touch-Safe Fuses

Prevent accidental contact with electrical circuits—these fuses have an enclosed design with recessed plug-in blades.
