When the rated functioning temperature of the thermal cutoff is exceeded, the device will fail open in the electrical circuit, breaking the flow of current. Selection Characteristics.

Thermal cutoff fuse

A thermal cutoff is an electrical safety device either a thermal fuse or thermal switch that interrupts electric current when heated to a specific temperature. These devices may be for one-time use a thermal fuse , or may be reset manually or automatically a thermal switch. 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 : 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 repair which would also replace the fuse or replacement at the end of service life. One mechanism is a small meltable pellet that holds down a spring. When the pellet melts, the spring is released, separating the contacts and breaking the circuit. Another mechanism is more similar to an electrical fuse, a fusible element that melts when subjected to temperature above its threshold. The difference from the electrical fuse is in using the surrounding temperature, instead of the temperature generated by ohmic heating of the fusible element. The elements are conductive and usually consist of binary or ternary fusible alloy of tin , bismuth , antimony , indium , lead , and other metals.

Most of us are familiar with the principle of fuses and how they work to help to keep electronics and other electrical systems operating smoothly. They protect overcurrents surging through a system and frying the other components or causing a fire. What is a thermal fuse and how does it work? According to SWE , a thermal fuse is a component that serves as a safety device. It is also known as a thermal cutoff. It opens circuits to prevent overheating. Thermal fuses are designed to detect heat that arises from an overcurrent that occurs within an electrical system. The cause for the overcurrent could either be due to a breakdown in a component or a short circuit.

Media Links. Hello, I was looking for a thermal fuse which would be used in a 24V DC application. They function as safety devices to disconnect the current to the heating element in case of a malfunction such as a defective thermostat that would otherwise allow the temperature to rise to dangerous levels, possibly starting a fire. All Rights Reserved. Available Lines. Earls, Robert E. Thermal switches on microprocessors often stop only the fetching of instructions to execute, reducing the clock rate to zero until a lower temperature is reached, while maintaining power to the cache to prevent data loss although a second switch, with a higher triggering temperature, usually turns off even the cache and forces the computer to reboot. Any help would be very much appreciated, Thanks in advance, Paul Sojo. In other projects. The thermal switch may be a bimetallic strip , often encased in a tubular glass bulb to protect it from dust or short circuit. Another common design uses a bimetallic shallow dome-shaped cap which "clicks" to an inside-out inverted cap shape when heated, such as the "Klixon" brand of thermal cutouts. Tools Tools.
