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
