Potential relay hvac.

Potential relay start capacitor cooling equipment relays. You sound like a real ahole. To order call 800 726 9696. This supco supr universal potential relay is used to start 1 phase capacitor type motors in air conditioning and refrigeration applications.

Provide additional starting torque for residential and commercial ac units heat pumps refrigerators and freezers with start assist kits. Tomczyk is a professor of hvac at ferris state university big rapids mi and the author of troubleshooting and servicing modern air conditioning refrigeration systems published by esco press. It is a replacement part with 110 to 270 vac pickup voltage. 50 60 hz culus contact rating 35 amp 400 vac operating position tab up instructions and wiring diagram included in each relay class b insulation c o m p.

Mars hvac potential relays mars series relays are manufactured for the hvac industry. Dependable cooling equipment relays from grainger help to ensure air conditioning and refrigeration equipment starts and runs smoothly. 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. Supco 9068 potential relay 35 a at 277 vac contact rating 50 60 hz cycle 502 v continuous coil voltage 325 345 pick up min max 135 drop max 4 8 out of 5 stars 6 13 95 13.

What a dip. 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. 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.
