About Fuses

Thermal Fuses

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

Fast-Acting Glass-Tube Fuses

These fuses open circuits quickly when surges are detected.

Time-Delay Glass-Tube 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.

Fuses for Sensitive Electronics

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

Fuses for Multimeters

Compatible with most multimeters, including Fluke.

Fast-Acting Ceramic-Tube Fuses

These fuses open circuits quickly when surges are detected.

Time-Delay Ceramic-Tube 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.

Automotive Fuses

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

Time-Delay Inline Fuses

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

High-Current Automotive Fuses

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

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.

Time-Delay Plug Base Fuses

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.

Fast-Acting Inline Fuses

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

Fast-Acting Lift Truck Fuses

These fuses open circuits quickly when surges are detected.

Time-Delay Lift Truck 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.
