Dual run capacitors serve two motor loads simultaneously from a single can, providing the starting and running capacitance required to maintain efficient motor operation. The round form factor is the industry-standard housing for residential and light commercial condensing units. Licensed HVAC technicians install this component as a direct replacement when diagnosing weak or failed capacitors during routine service calls or compressor hard-start events.\u003c\/p\u003e\u003cp\u003eThis capacitor is suited for split-system air conditioners and heat pumps where a single round capacitor supports both the compressor and the outdoor fan motor. It is commonly installed in residential condensing units and light commercial rooftop equipment that require a 45\/10 MFD dual run capacitor at 440 VAC. The 440-volt rating provides compatibility across both 370-volt and 440-volt rated systems, making it a practical single-stocking replacement for a wide range of equipment in the field.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual run design supports compressor and fan motor from one capacitor\u003c\/li\u003e\n\u003cli\u003e45\/10 MFD rating covers both motor loads in a single unit\u003c\/li\u003e\n\u003cli\u003e440 VAC voltage rating is compatible with 370 VAC and 440 VAC systems\u003c\/li\u003e\n\u003cli\u003eRound form factor fits standard capacitor brackets and mounting hardware\u003c\/li\u003e\n\u003cli\u003eSold individually as a single replacement unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for residential and light commercial split-system air conditioners and heat pumps requiring a round 45\/10 MFD dual run capacitor rated at 440 VAC.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDual run capacitors must be installed by a licensed HVAC technician. Always disconnect and lock out power to the condensing unit before servicing. Capacitors store a high-voltage charge even after power is removed  -  discharge the capacitor through a resistor before handling. Verify the replacement MFD ratings and voltage rating match the nameplate data on the existing capacitor before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 45\/10 MFD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 440 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Dual Run Capacitor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelling Unit\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MARS (Motors Armatures)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12872\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARS (MOTORS \u0026 ARMATURES)","offers":[{"title":"Default Title","offer_id":68102874923314,"sku":"12872","price":32.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1eb1aeeab4fd654b94260243fb97813_631c0639-02f2-4b0b-901b-b30b97b4381d.jpg?v=1793293919","url":"https:\/\/voomisupply.com\/products\/mars-12872-round-dual-run-capacitor-45-10-mfd-440v","provider":"Voomi Supply","version":"1.0","type":"link"}
