ABSTRACT:
A PTC motor starting device is disclosed including a PTC resistor body having a pair of electrodes disposed on the PTC body and a lead terminal extending outwardly from each of the electrodes. A heat sink material is disposed about the PTC resistor body to absorb the heat generated by the PTC resistor body to reduce the temperature of the PTC resistor body to a temperature below the anomalous or reset temperature. A casing is disposed about the heat sink material.
