When refrigerant-side pressure exceeds the rated threshold, this switch opens the control circuit, triggering a system shutdown before compressor or refrigerant-side damage can occur. It is an OEM Trane part, intended for installation by licensed HVAC technicians during preventive maintenance, system troubleshooting, or compressor replacement procedures.\u003c\/p\u003e\u003cp\u003eThis switch is used in Trane split-system and packaged HVAC equipment where high-side refrigerant pressure monitoring is required. It is typically wired into the low-voltage control circuit and mounted on the high-pressure refrigerant line or manifold. Applications span light commercial and residential central air systems where refrigerant overpressure protection is a code and manufacturer requirement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated at 800 psi closed, providing high-side overpressure protection for refrigerant circuits\u003c\/li\u003e\n\u003cli\u003eOEM Trane replacement part for accurate fit and reliable electrical contact behavior\u003c\/li\u003e\n\u003cli\u003eWired into low-voltage control circuit to trigger safe system shutdown on overpressure event\u003c\/li\u003e\n\u003cli\u003eSupports compressor protection by interrupting operation before pressure-side damage occurs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement high pressure cutout switch for Trane HVAC systems requiring refrigerant-side overpressure protection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician with EPA Section 608 refrigerant handling certification. Recover refrigerant and relieve system pressure before disconnecting the existing switch. De-energize all power to the unit at the disconnect before handling any control wiring. Refer to the equipment wiring diagram and applicable local mechanical codes when reconnecting the control circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 800 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch State at Rating\u003c\/strong\u003e: Closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: High Pressure Cutout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TRANE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SWT03172\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51233755234610,"sku":"SWT03172","price":184.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307616799.jpg?v=1780108441","url":"https:\/\/voomisupply.com\/products\/trane-swt03172-high-pressure-cutout-switch-800-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
