Temperature Fuses

Browse temperature fuses for over-temperature protection in electrical, electronic, HVAC, and industrial applications. Our range includes thermal fuses, thermal cutoff fuses, temperature cutoff fuses, and thermal safety fuses designed to disconnect electrical circuits when specified temperatures are exceeded. These non-resettable devices provide a simple and effective method of protecting equipment, components, and systems from heat-related damage. Available products include Microtemp temperature fuses, Aupo thermal fuses, SET Fuse thermal cutoffs, and Sung Woo SW-1 fuse products, with a range of operating temperatures and electrical ratings available.

Applications for Temperature Fuses

Temperature fuses are commonly used as a secondary safety device where overheating protection is required. Once the rated operating temperature is reached, the fuse opens the circuit permanently to help prevent damage to equipment and associated components.

Typical applications include:

Domestic Appliances: Kettles, coffee machines, heaters, dryers, and cooking equipment.
HVAC Systems: Heating units, air handling equipment, and ventilation systems.
Industrial Equipment: Machinery, electrical enclosures, and process control equipment.
Power Supplies and Transformers: Protection against excessive operating temperatures.
Electronic Assemblies: Thermal protection for temperature-sensitive components.

Choosing the Right Temperature Fuse

Selecting the correct temperature cutoff fuse requires consideration of operating temperature, maximum current, voltage rating, installation method, and equipment design. For applications with higher current requirements, high-current thermal fuse variants may be available with internal construction designed to interrupt larger fault currents. Ensuring the correct temperature rating is selected is essential to maintaining effective overheating protection while avoiding unnecessary operation during normal use.
