and 150 ° C within a +/-5 ° C tolerance. The bimetal disc has two different metals with different thermal expansion coefficients, so when the ambient temperature reaches a certain level, the bimetal disc bends and opens the contacts, in turn interrupting the current flow and protecting the circuit. One of the key advantages of the Mini- breaker is its low resistance level of less than 5 mΩ, which ensures that the Mini-breaker itself does not produce significant joule heating. Additionally, because the Mini-breaker reacts specifically to ambient temperature changes, it provides independent overtemperature protection and does not require ancillary components to function. The Mini-breaker is also resettable, which ensures that it does not bring any additional replacement costs. After the device has cooled down, the contacts close, and the device can be used again. This ability to self-reset is particularly useful in devices exposed to extreme temperatures or devices requiring constant protection from overtemperature conditions. Bourns circuit protection – The solutions available to engineers Bourns offers a variety of solutions for circuit protection, including transient voltage suppressor diodes, which protect against overvoltage events and other high-energy transients, and gas discharge tubes, which protect against lightning surges, power induction, and other high-voltage transients. Bourns also offers multilayer varistors (ZV, ZVHT, AV, and AVHT series) for overvoltage protection, lightning and other high energy surge protection (ZOV, CV, and SV series), and resettable fuses (polymeric positive temperature coefficient devices POWrFuse ™ and POWrTherm ™ ) for overcurrent protection.

Modules, which contain multiple solutions in small packages, are one such application where circuit protection is becoming increasingly important."
