Temperature protection devices are used to protect internal circuits or devices from overheating. The resistance of PTC thermistors rises rapidly when a certain temperature is exceeded, thus stopping the flow of current. This characteristic is self-regulating: Once the PTC cools down, it permits the current to flow again. bruce county public library youtubeNettetThermal protection of motors and transformers is another example of the versatility of PTC thermistors.
