Product Description
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>
* The dimension of the chip is small (size: 1.8X0.6mm)
* Response is fast
* Completed sereis available
* Stable performances
* Reliable for a long time use
* Especially when lacks of phases it can rapidly respond to protect the electric motor as well.

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).
| Electric motor insulation rank | Limited Working Temperature | Thermistor(TK) |
| Y | 90 | 80~85℃ |
| A | 105 | 95~100℃ |
| E | 120 | 110~115℃ |
| B | 130 | 120~125℃ |
| F | 155 | 145~150℃ |
| H | 180 | 170~175℃ |
| C | Above 180 | Above 180 |
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.
VIII Error and Measure Of The Customized Single Triple MZ6 PTC Thermistor
| Breakdown | Reason | Measure |
| Resistance value is too high(measure resistance of the outgoing line by Ohm band of an AVO meter,the resistance value of a single line is higher than 100Ω at 25℃) |
1. The lead of the thermistor opened a way or was in a bad contact. |
1.Check the lead of the thermistor whether open or not,or in the bad contact 2.Replace the themistor |
| Resistance value is too high(measure resistance of the outgoing line by Ohm band of an AVO meter,the resistance value of a single line is higher than 20Ω at 25℃) |
1.The lead of thermistor was in short circuit; 2.The thermistor was damaged |
Check the lead of the thermistor is in short circuit or not,and connect it. 2,Replace the thermistor |
| Sometimes be Normal,Sometimes be abormal, |
1.The lead of thermistor was in in bad contact; 2.The thermistor was damaged |
Connect the lead of the thermistor and the binding post tightly. |
