Thermal Fuses
Thermal Fuse Applications
In many applications, these devices are commonly used to back up primary devices as required by safety agencies. Thermal fuses are effective for totally shutting down a circuit when a catastrophic failure occurs. If your application demands repeatable operation at or near the maximum operating temperature for the materials you have selected, you may want to consider using a resettable type device. Basically if you choose to use a thermal fuse as a primary operating control, then you must consider that your application will become a disposable item if the thermal fuse functions. Since thermal fuses can not be reused after functioning, it is not possible to test them before or after installation.
