http://www.electricalterminology.com/what-is-thermistor-motor-protection-relay/ NettetLike thermostats, thermistors have a tamper proof pre-set switch point, with a reset only after the motor cools down. Due to their small size and heat sink construction, they have fast response times. In mush wound motors, non-rotor limited designs, thermistors can provide locked rotor protection. six ways cleanse detox
How to use PTC thermistors as current protection
Nettet11. mar. 2005 · A thermistor protection relay uses thermistors which are built inside the motor and measure the temperature of the motor windings. If the motor gets to hot, the thermistor relay will trip. An overload relay must always be used, a thermistor relay is only usefull if you are using the motor in S6 mode (temporary overload). NettetThe thermistor motor protection relay CM-MSS.41 is used to monitor the temperature of motors or generators equipped with PTC resistor sensors type A. The sensors are built-in into the motor windings, measuring the motor heating. In case of an increase of the temperature in the motor, the resistance of the PTC sensors will increase as well.
