Rated for 15 amps at 120 to 480 volts and 60 Hz, this switch operates reliably across a wide temperature range of 32 to 180 degrees F. It activates at a pressure differential of 0.07 inches water column, confirming that the supply fan is moving air before allowing downstream components to energize. Licensed HVAC technicians install this switch as part of fan proving and interlock circuits in commercial and residential equipment.\u003c\/p\u003e\n\u003cp\u003eThe swt01159 is suited for use in forced-air HVAC systems where fan status verification is required by the control sequence. Typical applications include air handling units, rooftop units, and split systems where the control board or DDC system needs proof-of-airflow before energizing heating or cooling stages. Its wide voltage rating makes it compatible with both single-phase and three-phase equipment operating at 120, 208, 240, or 480 volts at 60 Hz.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDetects airflow via 0.07 inches water column differential pressure setpoint\u003c\/li\u003e\n  \u003cli\u003eWide voltage range of 120 to 480 volts covers single-phase and three-phase applications\u003c\/li\u003e\n  \u003cli\u003e15-amp contact rating handles typical HVAC control and interlock loads\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of 32 to 180 degrees F suits both indoor and mechanical-room installations\u003c\/li\u003e\n  \u003cli\u003e60 Hz rated for standard North American HVAC equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fan status switch for TRANE HVAC equipment requiring a 15-amp, 120-480 volt differential pressure proving switch with a 0.07 inches water column activation point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before removing or installing the switch. The switch is typically tapped into the supply-air plenum or duct and wired into the fan interlock circuit per the equipment wiring diagram and applicable NEC requirements. Do not over-tighten pressure port fittings, and verify tubing connections are secure and free of kinks before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 15 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120-480 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 32-180 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActivation Pressure\u003c\/strong\u003e: 0.07 inches water column\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: swt01159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRANE","offers":[{"title":"Default Title","offer_id":51268835901746,"sku":"SWT01159","price":177.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912869.webp?v=1780707034","url":"https:\/\/voomisupply.com\/products\/trane-swt01159-fan-status-switch-15a-120-480v","provider":"Voomi Supply","version":"1.0","type":"link"}
