The Big Frog Supply SKU is stored as PSR22. When the controller energizes the relay’s 24 VAC coil, the contactor switches the separate pump power circuit, keeping the pump’s high-voltage load away from the controller output.\u003c\/p\u003e\n\u003cp\u003eHunter lists the PSR-22 for single-phase pumps up to approximately 2 HP at 120 VAC or 3 HP at 230 VAC, with a maximum full-load rating of 30 amps and maximum resistive rating of 40 amps. Pump horsepower alone is not sufficient for selection: confirm voltage, phase, motor nameplate full-load current, starting current, controller output, conductor size, disconnecting means, and local electrical requirements.\u003c\/p\u003e\n\u003cp\u003eThe outdoor enclosure includes 24 VAC flying leads for the controller connection and multiple conduit knockouts for field wiring. Hunter recommends mounting the relay at least 15 feet from the irrigation controller to reduce the possibility of electrical noise reaching the controller through the low-voltage wiring.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDouble-pole, single-throw pump start relay\u003c\/li\u003e\n\u003cli\u003e24 VAC controller coil with flying leads\u003c\/li\u003e\n\u003cli\u003eFor compatible 120 VAC pumps up to approximately 2 HP\u003c\/li\u003e\n\u003cli\u003eFor compatible 230 VAC single-phase pumps up to approximately 3 HP\u003c\/li\u003e\n\u003cli\u003eMaximum full-load rating of 30 amps\u003c\/li\u003e\n\u003cli\u003eMaximum resistive rating of 40 amps\u003c\/li\u003e\n\u003cli\u003eSuitable for supported conventional or two-wire decoder activation\u003c\/li\u003e\n\u003cli\u003eOutdoor-rated IP44 enclosure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCommon Uses\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStarting an irrigation well pump from a controller\u003c\/li\u003e\n\u003cli\u003eOperating a booster pump during scheduled watering\u003c\/li\u003e\n\u003cli\u003ePond, creek, or cistern-fed irrigation systems\u003c\/li\u003e\n\u003cli\u003eReplacing a matching Hunter PSR-22 relay\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility and Installation Notes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVerify pump voltage, phase, horsepower, full-load current, and starting current before selection.\u003c\/li\u003e\n\u003cli\u003eConfirm the irrigation controller or decoder output is compatible with the 24 VAC relay coil.\u003c\/li\u003e\n\u003cli\u003eMount at least 15 feet from the irrigation controller unless the current Hunter instructions specify otherwise for the installation.\u003c\/li\u003e\n\u003cli\u003eDo not connect a pump motor directly to the irrigation controller.\u003c\/li\u003e\n\u003cli\u003eHigh-voltage wiring and relay installation should be completed by a licensed electrician in accordance with applicable codes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eDoes the PSR-22 power the pump?\u003c\/h3\u003e\n\u003cp\u003eNo. It switches the separate pump power circuit when its 24 VAC coil is energized by the irrigation control system.\u003c\/p\u003e\n\u003ch3\u003eCan it operate a three-phase pump?\u003c\/h3\u003e\n\u003cp\u003eNo three-phase horsepower rating is published for PSR-22.
