Nettetthermal delay, tripping temperature can be affected by carelessfitting, large size compared to modern sensors. Thermistor is a small resistance sensor with non-linear resistance temperature relationship. There - are two types of thermistors negative temperature coefficient (NTC) and positive temperature coefficient (PTC) - thermistors. 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).
