NettetCharacteristics of PTC Thermistors. Silistors have a linear resistance-temperature characteristic, with a slope that is relatively small through most of their operational range. They may exhibit a negative temperature coefficient at temperatures above 150 °C. Silistors have temperature coefﬁcients of resistance of about 0.7 to 0.8% / °C.

NettetFirst I suggest you to check the settings of the protections that gives the command to trip (soft-starter or relay). Another cause assuming reduced voltage start, star/delta, … NettetPTC thermistors can effectively protect motors from such overcurrent. For example, if the side mirror of a car is blocked by an object, the motor will lock when an attempt is … Nettetif the motor temperature is still above the trip threshold, the trip cannot be reset. Refer to the Chapter 10 in the AC30 product manual (HA501718U002) for information on trips, possible causes, and how to reset them. A motor thermistor fault is identified in that manual as ID13 (Motor Overtemp). prof shinga feresu

NettetThermistors are positive temperature coefficient resistors - low resistance when detecting low temperatures and high resistance (open circuit) when above the tripping temperature. No adjustment is possible. The resistance of the thermistor will increase very rapidly (equal to contacts opening) when the switching temperature is reached.
