It combines a low-pressure clutch cutoff, a high-pressure clutch cutoff, and an electric fan engagement signal into one compact fitting, cutting the compressor clutch out at 30 PSI low side and 406 PSI high side, and switching on the fan circuit at 254 PSI. Vintage Air recommends it for any system running electric cooling fans.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/store-xovjmui41g.mybigcommerce.com\/content\/11076-VUS.pdf\" target=\"_blank\" rel=\"noopener\"\u003eVintage Air Installation Instructions (PDF)\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/store-xovjmui41g.mybigcommerce.com\/content\/regulatory\/Prop-65-warning-lead.pdf\" target=\"_blank\" rel=\"noopener\"\u003eCalifornia Proposition 65 Warning (PDF)\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSwitch type: Trinary (low cutoff \/ high cutoff \/ fan signal)\u003c\/li\u003e\n\u003cli\u003eThread: Female\u003c\/li\u003e\n\u003cli\u003eLow pressure cutoff: 30 PSI\u003c\/li\u003e\n\u003cli\u003eHigh pressure cutoff: 406 PSI\u003c\/li\u003e\n\u003cli\u003eElectric fan engagement signal: 254 PSI\u003c\/li\u003e\n\u003cli\u003ePart number: 11076-VUS\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat is the difference between a trinary and binary switch?\u003c\/h5\u003e\u003cp\u003eA trinary switch adds a third function, an electric fan engagement signal, on top of the low- and high-pressure compressor clutch cutoffs found on a binary switch.
