DTA04 is a motor thermistor monitoring 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 2 outputs which operate in a complementary mode. The DTA04 can be set to operate as MANUAL or AUTO reset. When set to manual, the front LED will notify when the motor temperature is back to normal avoiding to try to restore operation uselessly.
