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.

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

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.

These fuses open circuits quickly when surges are detected.

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.

These fuses open circuits quickly when surges are detected.

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

These fuses open circuits quickly when surges are detected.

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.

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.

These fuses open circuits quickly when surges are detected.

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.

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

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

These fuses open circuits quickly when surges are detected.

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.

With a quicker response than standard fast-acting fuses, these fuses provide the best protection for sensitive electronics.

These fuses open circuits quickly when surges are detected.

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.

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.

These fuses open circuits quickly when surges are detected.

Developed for the solar industry, these fuses meet the needs of high-voltage DC applications.

Compatible with most multimeters, including Fluke.

Use these fuses with equipment made in Europe.

Also known as diazed or Type D fuses.

These fuses open circuits quickly when surges are detected.

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.

These fuses are suitable for low-voltage automotive and other electronic applications.

Suitable for battery and alternator circuit protection, these fuses can handle higher current than standard automotive 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.

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.

Also known as thermal cut-offs, these fuses prevent equipment from overheating by opening circuits to cut off power.

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

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

Fast-Acting Inline Fuses

Also known as LGR fuses, these fuses open circuits quickly when surges are detected.
