The thermistor cut-out value is > 3 kΩ.
Integrate a thermistor (PTC sensor) in the motor for winding protection.
Motor protection can be implemented using a range of techniques: PTC sensor in motor windings; mechanical
thermal switch (Klixon type); or Electronic Thermal Relay (ETR).

Using a digital input and 24 V as power supply:

Example: The frequency converter trips when the motor temperature is too high.
