MZ6 PTC thermistor, positive temperature coefficient. When the temperature of the motor coil exceeds, the resistance of PTC will increase, the signal will be transmitted to the PTC module, driving the control circuit to disconnect the main power supply, thus protecting the motor.
Features :
Easy to install;
Cost effective;
Low energy consumption (dissipation power is 0.8va);
Highly reliable and safer;
Accurate temperature calculation;
Can be customized;
