Engineered with an automatic reset mechanism, this switch protects compressors against loss of charge and low suction pressure by opening the electrical circuit at 5 ± 4 PSI (~0.34 bar) and automatically resetting when pressure rises back to 20 ± 7 PSI (~1.38 bar). Featuring a 1\/4in female flare brass connection with an internal valve depressor and pre-wired insulated leads, it provides reliable, factory-calibrated pressure safety 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-03L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e018-005D020G\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eComponent Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLow 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\u003e5 ± 4 PSI (~0.34 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\u003e20 ± 7 PSI (~1.38 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":58620289843584,"sku":"CTR-GEN-YK03L-0520","price":9.6,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/6647\/5904\/files\/yk-low-pressure-switch-auto-reset-1-4in-female-flare.jpg?v=1785497815","url":"https:\/\/rasonline.co.uk\/products\/yk-03l-low-pressure-switch-auto-reset-1-4in-female-flare-open-5-psi-close-20-psi","provider":"Refrigeration \u0026 Air Conditioning Supplies Ltd","version":"1.0","type":"link"}
