MZ6T PTC motor protection type thermistor is specially designed for over-temperature protection of motors and other parts according to international standards DIN-44081 and DIN-44082. The PTC thermistor is placed in the three-phase winding of the motor. When the temperature reaches the insulation level temperature, the resistance of the PTC rises, and the high-resistance signal is transmitted to the control protector, and the protector disconnects the motor line according to the signal to protect the motor.
