How to Choose the Best Thermal Cutoffs

Choosing the Right Type

Thermal cutoffs come in various forms, including:
  • Axial leaded devices: Common in many consumer electronics.
  • Radial leaded devices: Offer different mounting options.
  • Surface mount devices (SMD): For compact electronic boards.
Consult your device's specifications or a qualified technician to determine the most suitable type for your needs.

Frequently Asked Questions

What is the difference between a thermal cutoff and a thermal switch?
A thermal cutoff is a single-use device that permanently breaks a circuit when it reaches a specific temperature. A thermal switch, on the other hand, is typically resettable and can open and close a circuit multiple times as the temperature fluctuates.
How do I determine the correct temperature rating for a thermal cutoff?
The temperature rating should be higher than the normal operating temperature of the component or device being protected, but low enough to prevent damage or fire in case of a malfunction. It's often recommended to choose a rating that is 20-30u00b0C above the maximum expected operating temperature.
Can I replace a blown thermal cutoff with a higher temperature rated one?
It is strongly advised not to replace a thermal cutoff with one of a higher temperature rating. Doing so bypasses the safety mechanism and could lead to overheating, damage to the device, or fire. Always use a replacement with the exact same specifications.
Are thermal cutoffs universal?
No, thermal cutoffs are not universal. They come in various temperature ratings, current and voltage ratings, and physical sizes. It is essential to match the replacement cutoff's specifications precisely to the original one for safety and proper function.
Where should a thermal cutoff be placed in a circuit?
The thermal cutoff should be placed as close as possible to the component or area that is most likely to overheat. This ensures it can accurately sense an abnormal temperature rise and quickly interrupt the circuit.
