Types Of Thermal Fuse

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.

Types of thermal fuse.

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. 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. The fuse element in a thermal fuse is made up of a temperature sensitive alloy. Thermal fuses are also called as thermal links or thermal cutouts tco.

A wide variety of thermal fuse types options are available to you such as iec csa. In a thermal fuse the fuse element hold a mechanical spring contact which is normally closed. 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. The fuse element in a thermal fuse holds a mechanical spring contact which is normally.

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