Resettable Thermal Fuses

Resettable thermal fuses are a reusable type of circuit protection device used in heating applications. They provide a weak link in a circuit, meaning that when a fault such as overcurrent or a short circuit is detected, the fuse will break the circuit and stop the flow of current, preventing further damage from occurring.

How do resettable thermal fuses work?

Resettable thermal fuses act in a similar way to a resistor, in that they increase their resistance as the temperature rises. When the temperature reaches a certain level, a wax pellet inside of the fuse will melt, cutting off the flow of electrical current, and then when the temperature drops again the wax will solidify, allowing the circuit to function again. Unlike non-resettable thermal fuses, they can be used more than once.

Types of resettable thermal fuses

Resettable thermal fuses mainly vary by their functioning temperature, which will depend on the heating application they are used with. They can also have differing levels of trip and reset tolerance, also measured by temperature.
