Thermal Fuse Functions and Applications

banner4(1)

A thermal fuse functions by providing overheat protection for electrical products such as home appliances, battery packs, motors, power supplies, transformers, heating and air-conditioning equipment and various electronic devices. A thermal cutoff (TCO) is designed into electrical circuits to cutoff the electrical power in the circuit case of overheating, either as a backup in series to a thermostat or on their own. Thermal cut-offs are used to prevent uncontrolled overheating which can lead to catastrophic consequences. We work with Engineers and Buyers at the manufacturers of many types of electrical components, devices and finished products.
