Run capacitors store and release electrical energy to maintain steady motor operation in compressors and fan motors. This round-style capacitor delivers a 55 MFD rating for the compressor winding and a 10 MFD rating for the condenser fan motor, both on a single 440V unit. HVAC technicians install this component during routine capacitor replacement or as part of a compressor or fan motor service call. Its compact round form factor fits standard capacitor mounting brackets in most air conditioning and heat pump condensing units.\u003c\/p\u003e\u003cp\u003eThis capacitor is suited for split-system air conditioners and heat pumps where a single dual-rated capacitor serves both the compressor and outdoor fan motor. It is a common replacement part during the cooling season when capacitor failure causes hard-start conditions, motor humming, or system shutdown. The round form factor and standard MFD ratings make it a practical direct-replacement option for techs stocking a service van with commonly needed capacitor values.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual run capacitor supports both compressor and condenser fan motor circuits in one unit\u003c\/li\u003e\n\u003cli\u003e55\/10 MFD rating covers the most common compressor and fan motor pairing in residential condensing units\u003c\/li\u003e\n\u003cli\u003e440V rating provides voltage headroom for both 208\/230V single-phase applications\u003c\/li\u003e\n\u003cli\u003eRound form factor fits standard capacitor brackets and retention straps\u003c\/li\u003e\n\u003cli\u003eCompact dimensions allow installation in tight equipment cabinets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 55\/10 MFD, 440V round capacitor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDual run capacitors are installed by licensed HVAC technicians. Always disconnect and lock out power to the condensing unit before handling capacitors, and discharge the capacitor terminals using an approved resistor or discharge tool before removing any wiring. Capacitors can retain a lethal charge even after power is removed. Follow local electrical codes and manufacturer wiring diagrams when reconnecting terminals to the compressor, fan motor, and contactor.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 55\/10 MFD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 440 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: M12299\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51383125377330,"sku":"M12299","price":47.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670876.png?v=1782588285","url":"https:\/\/voomisupply.com\/products\/rectorseal-m12299-dual-run-capacitor-55-10-mfd-440v","provider":"Voomi Supply","version":"1.0","type":"link"}
