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.
NettetMany motor protection devices protect motors from overheating and overload based on the motor’s current information. The real temperature is not detected by these devices. The temperature in the thermal hot spots of a motor can be higher than expected due to motor location or insufficient cooling. NettetThere are many benefits of using a motor thermal protection switch: ü Automatically shutting off the motor to prevent damage due to overheating. ü Automatic turn-on …
