★principle
PTC thermistor is positive temp. coefficient resistor。When the temp. reach to curie point，the semiconductor ceramic begin to phase transit，its resistor value increase abruptly with temp.'s rising，near the control temp. point Tk，the changes is remarkable clear，to funct the control circuit。
MZ6 series PTC used for motor protection，for different temp.，also for overheat protect of other important part.such as putting PTC in motor's 3-phase coil，when the coil temp.reach to insulating grade temp.the value of PTC rising。This signal send to the protector to cut motor's current，so as to protect the motor。
