Types Of Thermal Fuse

The fuse element in a thermal fuse is made up of a temperature sensitive alloy.

Types of thermal fuse.

A single use device that cannot be reset and must be replaced when it fails or is triggered a thermal fuse is used when the overheating is a result of a rare occurrence such as failure requiring. A thermal fuse is a cutoff which uses a one time fusible link unlike a thermal switch which may automatically reset itself when the temperature drops the thermal fuse is more like an electrical fuse. Also known as thermal cut offs these fuses prevent equipment from overheating they work similar to electrical fuses when the device or environment becomes too hot the fuse opens and the device turns off. A wide variety of thermal fuse types options are available to you such as iec csa.

Thermal fuses are also called as thermal links or thermal cutouts tco. When high currents due to over current and short circuit flow through the elements of the fuse the fuse elements melts down which lead to release the spring mechanism and prevent the arc and fire and protect the connected circuit. In a thermal fuse the fuse element hold a mechanical spring contact which is normally closed. Aside from thermal fuses many appliances and commercial machinery use thermal switches.

These can be made using gas metal contacts mercury or other mechanisms but the main difference between a thermal fuse and a thermal switch is that thermal fuses are single use. Thermal fuses are one time only fuses and are basically a temperature sensitive fuses.
