Potential relay hvac.

This supco supr universal potential relay is used to start 1 phase capacitor type motors in air conditioning and refrigeration applications. Potential relay start capacitor cooling equipment relays. Tomczyk will cover potential relay rating specifications and troubleshooting. To order call 800 726 9696.

You sound like a real ahole. 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. What a dip.
