Designed with an automatic reset mechanism, this switch safeguards compressors against excessive discharge pressure by opening the electrical circuit at 410 ± 15 PSI (~28.3 bar) and automatically resetting when head pressure drops to 310 ± 15 PSI (~21.4 bar). Featuring a 1\/4in female flare brass connection with an internal valve depressor and pre-wired insulated leads, it provides dependable, factory-calibrated high-pressure protection for refrigeration engineers and OEMs.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable class=\"trade-spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel Series\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eYK-03H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e018-410R310R\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eComponent Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHigh Pressure Switch (Capsule Type)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eReset Action\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAuto Reset (Automatic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCut-Out Pressure (OPEN)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e410 ± 15 PSI (~28.3 bar)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCut-In Pressure (CLOSE)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e310 ± 15 PSI (~21.4 bar)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eElectrical Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e250V AC, 6A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePressure Connection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1\/4in Female Flare (SAE Thread)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFitting Construction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBrass Coupling with Internal Valve Depressor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWiring Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePre-wired Insulated Flying Leads\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMedia Compatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStandard Commercial Refrigerants and Synthetic\/Mineral Oils\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Generic","offers":[{"title":"Default Title","offer_id":58620290564480,"sku":"CTR-GEN-YK03H-410310","price":9.6,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/6647\/5904\/files\/yk-high-pressure-switch-auto-reset-1-4in-female-flare.jpg?v=1785497817","url":"https:\/\/rasonline.co.uk\/products\/yk-03h-high-pressure-switch-auto-reset-1-4in-female-flare-open-410-psi-close-310-psi","provider":"Refrigeration \u0026 Air Conditioning Supplies Ltd","version":"1.0","type":"link"}
