Single Triple MZ6 PTC Thermistor

Customized Single Triple MZ6 PTC Thermistor 60~180C 520mm For Electric Motor Protection

I Overview Of The Customized Single Triple MZ6 PTC Thermistor

MZ6 Type PTC Thermistors is designed for electric motor Protection and widely used all the world.The key technology was introduced from the
United States of America in 1990s and has had more than 10 years production experience. It is availlable for different products and also over temperature protection on the main parts inside the electric motor. For example, the PTC thermistors are embedded into the three-phase Electric motor stator winding. When the temperature of Stator winding of electric motor up to the insulation grade temperature of insulated material the resistance of PTC Thermistors wil rise at the same time.And the signal is transmitted to the protector to switch off the current of electric motor and finally prevent the electric motor form being burned out.

II Features Of The Customized Single Triple MZ6 PTC Thermistor

* Mz6 type ptc thermistors For Electric Motor Protection accords with the international standard of DN440S1/DIN44S0S>

Yellow wires are used between adjoining thermistors.


VI Operating Instruction Of The Customized Single Triple MZ6 PTC Thermistor

The electric motor of different insulation rank selects the different Tk temperature thermistor, its parameter is shown at following table(only reference).

VII Note for mounting Of The Customized Single Triple MZ6 PTC Thermistor


1. Insert wire in the winding wire slot of the motor,make it tidy, and then mount the PTC thermistor in the coil of motor(as shown in figure). 2.White mounting,do not hard beat or press the sensing area of the thermistor for fear that the internal precise structure of the product might be damaged.3. While mounting,do not extremely hard pull the outgoing line of the product for fear that the outgoing line might be pulled apart.4.Before connecting,read the technical information about PTC temperature control module(the former GRB motor overheat protector) for fear that the thermistor might be damaged. 5.Securely connect the outgoing line in the specified connection position.
