MZ6D series of PTC embedded sensor

Provides economical and reliable protection for 3-phase motors•

Provides economical and reliable protection for 3-phase motors• Sharp increase in resistance near trip temperature• Wide trip temperature range from 85°C to 135°C• Rugged design for installation during motor manufacturing• Directly senses motor winding temperature• Rapid response to changes in temperature• No field adjustment required

• Directly senses motor winding temperature• Rapid response to changes in temperature• No field adjustment required

Summary The product which carried out German DIN44081,DIN44082 standard, featured with high sensitivity and long life, the insulation strength is AC6KV , it can be used for explosion-proof motor for protection places which over  temperature, and it also can be single or many series match with motor protector using , The temperature-measuring terminal of the sensor shall be installed in where it supposed to be,   wire shall be connected to signal input terminal of the motor protector, as soon as the temperature is approaching temperature rating of insulation, input resistance figure will reach action valve value of the protector, so the protector will simultaneously cut off the power and the protection shall be realized.Technical data the controlled temperatures range from Tk 60°Cto Tk 180 ,there is 5 °Cinterval between the controlled  temperature Tk according to our specification ,we also can produce one chips to six chips
