DTA71CM24

DTA71CM24 is a motor thermistor relay. Through the motor internal PTC or PTCs the DTA detects when one or more motor windings are exceeding the maximum operating winding temperature. The PTC type installed in the motor is different according to the motor insulation temperature. The temperature triggering threshold is determined by the PTC type. The relay is equipped with 1 SPDT relay output and AUTO reset. The thresholds are determined by the motor internal PTC. Beyond the specified temperature the output stops the motor/s. This type of controller allows limitation of false alarms which may be the cause of useless interruptions of production systems when compared with other electrical measures (i.e. current or power). It can be useful in all applications where motors are used especially where overloads are frequent and may cause motor damage: pumping stations, water treatment, conveyors, material handling, HVAC, chillers etc.
