Run capacitors maintain a continuous phase shift in single-phase motors, keeping the auxiliary winding energized during normal operation. This improves motor efficiency and helps prevent premature motor failure. The M12037 is rated at 440 volts, making it suitable for both 208\/230-volt and 277-volt applications. Its oval form factor fits standard capacitor brackets found in most residential and light commercial air conditioning and heat pump equipment. HVAC technicians install this capacitor during routine maintenance or when diagnosing capacitor-related motor faults.\u003c\/p\u003e\n\u003cp\u003eThe M12037 is used in single-phase PSC (permanent split capacitor) motors powering condenser fan motors and compressors in residential and light commercial split-system air conditioners and heat pumps. The oval shape fits securely in factory capacitor brackets without modification in most applications. Its 440-volt rating provides operating headroom above standard 240-volt supply voltages, which helps extend service life under normal load conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20 MFD capacitance rating for PSC motor circuits\u003c\/li\u003e\n  \u003cli\u003e440-volt rating suitable for 208\/230-volt and 277-volt equipment\u003c\/li\u003e\n  \u003cli\u003eOval form factor fits standard condenser unit capacitor brackets\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions: 1.806 inches wide by 2.806 inches long by 3.125 inches tall\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement run capacitor for single-phase PSC condenser fan motors and compressors in residential and light commercial HVAC equipment requiring a 20 MFD, 440-volt oval capacitor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of a run capacitor should be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before accessing the capacitor compartment, and discharge the existing capacitor fully before handling it, as run capacitors can retain a lethal charge even after power is removed. Verify the MFD rating and voltage rating of the replacement capacitor match the equipment nameplate requirements before installation. Follow all applicable local electrical codes and NEC guidelines when servicing capacitor circuits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 20 MFD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 440 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Oval\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.806 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.806 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 685744120377\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: M12037\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51383636984114,"sku":"M12037","price":20.76,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670829.png?v=1782602744","url":"https:\/\/voomisupply.com\/products\/rectorseal-m12037-run-capacitor-20-mfd-440v-oval","provider":"Voomi Supply","version":"1.0","type":"link"}
