THERMISTOR PRODUCTS  
PTC THERMISTOR  
FOR MOTOR STARTER  
PTH7M/491 Se rie s  
The PTH7M/491 Series is specifically designed for appliance  
application in refrigerators, air conditioners and freezers and feature  
an encapsulated construction and “quick connect” terminations to  
facilitate installation and service. The exceptionally low resistance  
of this Posistor® in the off condition allows a maximum current to  
flow in the starting winding. As the temperature of the Posistor®  
increases, so does its resistance. The starting winding is essentially  
isolated from the running winding once the motor has reached  
operating speed because of this increase in Posistor® resistance.  
FEATURES  
ꢀ No starting contacts to pit or wear  
ꢀ May be directly substituted for start switches without  
redesigning motor  
ꢀ Encapsulated construction  
ꢀ Acoustically and electrically noise free  
ꢀ Vibration and shock resistant  
ꢀ Long operating life  
ꢀ Ideal for explosion proof motor applications  
ꢀ Quick connect terminations
