Rated at 125 VA at 24 VAC and 375 VA at 120\/277 VAC pilot duty, this switch opens at 610 psi and closes at 420 psi to protect the refrigerant circuit from dangerously high head pressure conditions. The 18 AWG lead wire connects into the low-voltage control circuit, and the 1\/4 inch flare screw-on fitting allows for direct installation on the high-side refrigerant line without a capillary tube. Licensed HVAC technicians install this component during routine service or system repair.\u003c\/p\u003e\u003cp\u003eThis high pressure limit switch is intended for residential air conditioning applications where high-side refrigerant pressure monitoring is required. It is specified for use on the RUUD RA17 air conditioner series. The auto reset function automatically restores the circuit once system pressure drops back within the safe operating range, eliminating the need for manual reset during normal cycling events. It is mounted directly on the high-side refrigerant line using the 1\/4 inch flare connection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOpens at 610 psi to interrupt the control circuit and protect against high head pressure\u003c\/li\u003e\n\u003cli\u003eCloses at 420 psi for automatic reset once pressure normalizes\u003c\/li\u003e\n\u003cli\u003eRated 125 VA at 24 VAC and 375 VA at 120\/277 VAC pilot duty\u003c\/li\u003e\n\u003cli\u003e18 AWG lead wire for low-voltage control circuit wiring\u003c\/li\u003e\n\u003cli\u003e1\/4 inch flare screw-on mounting — no capillary tube required\u003c\/li\u003e\n\u003cli\u003eAuto reset operation reduces manual service calls for normal pressure events\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on the RUUD RA17 air conditioner series as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with applicable mechanical and refrigeration codes. Recover refrigerant and relieve system pressure before removing or installing any high-side pressure control to prevent injury. Connect lead wires into the low-voltage control circuit following the equipment wiring diagram. Verify all flare fittings are leak-free before recharging the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: High Pressure Limit, Auto Reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Pressure\u003c\/strong\u003e: 610 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClose Pressure\u003c\/strong\u003e: 420 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Duty Rating\u003c\/strong\u003e: 125 VA at 24 VAC; 375 VA at 120\/277 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Wire Gauge\u003c\/strong\u003e: 18 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: 1\/4 inch flare screw-on\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapillary Tube\u003c\/strong\u003e: Not required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RUUD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 47-102290-01\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RUUD","offers":[{"title":"Default Title","offer_id":51284068041010,"sku":"47-102290-01","price":25.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277772.jpg?v=1781067694","url":"https:\/\/voomisupply.com\/products\/ruud-47-102290-01-high-pressure-limit-switch-610-psi-auto-reset","provider":"Voomi Supply","version":"1.0","type":"link"}
