Types Of Thermal Fuse

Some thermal switches are also single use but many types can simply be reset.

Types of thermal fuse.

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. 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. They are non resettable so you ll need to replace them once they open choose a fuse based on your device s normal operating temperature and the temperature at which you want the fuse to.

The fuse element in a thermal fuse is made up of a temperature sensitive alloy. 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. The fuse element in a thermal fuse holds a mechanical spring contact which is normally. 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.

Thermal fuses are also called as thermal links or thermal cutouts tco. Thermal fuses are one time only fuses and are basically a temperature sensitive fuses.
