Potential Relay Hvac
Dependable cooling equipment relays from grainger help to ensure air conditioning and refrigeration equipment starts and runs smoothly.
Potential relay hvac. This supco supr universal potential relay is used to start 1 phase capacitor type motors in air conditioning and refrigeration applications. To order call 800 726 9696. To order call. It is a replacement part with 110 to 270 vac pickup voltage.
Everyone in the field calls them potential relays in addition look at a schematic on an ac and you ll find pr potential relay. Always use the model number of the old relay when ordering a new one or cross reference it with a different manufacturer s relay. 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. What a dip.
These relays meet all requirements for original equipment relays. Mars hvac potential relays mars series relays are manufactured for the hvac industry. Provide additional starting torque for residential and commercial ac units heat pumps refrigerators and freezers with start assist kits. You sound like a real ahole.
Tomczyk is a professor of hvacr at ferris state university big rapids mi and the author of troubleshooting and servicing modern air conditioning refrigeration systems published by esco press. Tomczyk will cover potential relay rating specifications and troubleshooting. 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. 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.
