Run capacitors store and release electrical energy to keep single-phase motors running smoothly after startup, maintaining the phase shift needed for efficient rotation. This unit is housed in a compact round aluminum can measuring 1.75 inches in diameter and 4.25 inches tall. It is installed by licensed HVAC technicians as a direct replacement in air conditioning condensers, heat pumps, and air handlers where motor reliability is critical.\u003c\/p\u003e\n\u003cp\u003eThis capacitor is suited for residential and light commercial HVAC applications where a 40 MFD, 370-volt round capacitor is specified. Common install locations include condenser fan motors and compressor circuits in split-system air conditioners and heat pumps. Its round form factor fits standard capacitor mounting brackets found in most outdoor condenser units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40 MFD capacitance rating for continuous-duty motor run applications\u003c\/li\u003e\n  \u003cli\u003e370-volt AC rating suitable for standard residential HVAC motor circuits\u003c\/li\u003e\n  \u003cli\u003eRound housing fits widely used condenser and air handler capacitor mounts\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 1.75 inches wide by 4.25 inches tall for tight cabinet installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for single-phase HVAC motors requiring a 40 MFD, 370-volt round run capacitor in residential and light commercial systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eRun capacitors are installed by qualified HVAC technicians. Always disconnect and lock out power to the unit before servicing capacitors, as they can hold a dangerous charge even after equipment is shut off. Discharge the capacitor using an approved discharge tool before handling. Follow all applicable local codes and manufacturer wiring diagrams during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 40 MFD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 370 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 685744122210\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: RECTORSEAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M12221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51383649141042,"sku":"M12221","price":25.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670758.png?v=1782603128","url":"https:\/\/voomisupply.com\/products\/rectorseal-m12221-round-run-capacitor-40-mfd-370v","provider":"Voomi Supply","version":"1.0","type":"link"}
