Abstract: A combination run capacitor/positive temperature coefficient resistor/overload (CAP/PTCR/OL) module is described. The cover of the combination housing includes a capacitor compartment and terminal openings for receiving blade terminals of a run capacitor. The terminal openings in the cover align with blade receiving receptacles coupled to the PTCR start circuit. The blade terminals of a run capacitor are inserted into the receptacle openings and into electrical engagement with the blade receiving receptacles. The capacitor is supported and protected by a potting mixture filling the capacitor compartment.

Abstract: A motor start switch includes a temperature responsive resistor element and a cutout switch electrically connected in series with a start winding of an electric motor. The cutout switch is in thermal contact with the temperature responsive resistor element so that heat from the temperature responsive resistor element is transferred to a bimetal element in the cutout switch, causing the bimetal element to open the switch. Heat from a motor overload protector provides heat to maintain the bimetal element in an open position. As heat to operate the temperature responsive resistor element is obtained from existing circuit elements, the efficiency rating of the motor is unaffected.

Abstract: A motor start switch includes a temperature responsive resistor element and a bimetal cutout switch electrically connected in series with a start winding of an electric motor. The cutout switch is operable between an open position disconnecting the temperature responsive resistor from the start winding, and a closed position electrically connecting the temperature responsive resistor to the start winding. The cutout switch transitions from the open position to the closed position due to current flowing through, and heating, a bimetal element in the cutout switch.
