This pickup voltage is potential voltage that exists in the start winding when a motor gets above about 75 running speed and it is generated in the start winding by the motor itself not the capacitor. Always use the model number of the old relay when ordering a new one or cross reference it with a different manufacturer s relay. To order call 800 726 9696.

It is a replacement part with 110 to 270 vac pickup voltage. Provide additional starting torque for residential and commercial ac units heat pumps refrigerators and freezers with start assist kits. The potential relay is normally closed and it opens when a sufficient pickup voltage is present between the 5 and 2 terminals on the relay. To order call.
