Types Of Thermal Fuse

Thermal fuses are one time only fuses and are basically a temperature sensitive fuses.

Types of thermal fuse.

The fuse element in a thermal fuse holds a mechanical spring contact which is normally. In a thermal fuse the fuse element hold a mechanical spring contact which is normally closed. 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. Some thermal switches are also single use but many types can simply be reset.

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. 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 is made up of a temperature sensitive alloy. 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.

Aside from thermal fuses many appliances and commercial machinery use thermal switches. 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.
