It operates on 50\/60 Hz systems, making it suitable for both North American and international-frequency applications. Dual run capacitors serve two motor windings simultaneously, providing the start and run assist needed for the compressor and the condenser fan motor within a single enclosure. HVAC technicians install this capacitor as a direct replacement when original components fail, restoring proper motor starting torque and run efficiency in split-system air conditioners and heat pumps.\u003c\/p\u003e\n\u003cp\u003eThis capacitor is used in residential and light-commercial HVAC equipment where a single round dual-section capacitor powers both the compressor and condenser fan motor. The 440-volt rating provides a safety margin above standard 240-volt equipment, and the 370-volt rating satisfies minimum OEM requirements on many units. It is a common replacement item for HVAC service technicians performing seasonal tune-ups, capacitor failure callbacks, or component-level troubleshooting on condensing units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-section design powers compressor and condenser fan motor from one capacitor\u003c\/li\u003e\n  \u003cli\u003e80\/5 MFD capacitance rating covers high-draw compressor and lower-draw fan motor simultaneously\u003c\/li\u003e\n  \u003cli\u003e440\/370-volt rating suits a wide range of residential and light-commercial condensing units\u003c\/li\u003e\n  \u003cli\u003eRound form factor fits standard capacitor mounting brackets and clips\u003c\/li\u003e\n  \u003cli\u003e50\/60 Hz compatibility supports standard North American HVAC system frequencies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement dual run capacitor for residential and light-commercial air conditioning and heat pump condensing units requiring an 80\/5 MFD, 440\/370-volt round capacitor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCapacitor replacement is performed by licensed HVAC technicians. Shut off all power at the disconnect and verify zero voltage with a meter before handling the capacitor, as a failed capacitor can retain a dangerous charge. Discharge the capacitor through a resistor before removing wiring. Follow all local codes and manufacturer wiring diagrams when reconnecting terminals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 80\/5 MFD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 440\/370 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 50\/60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Dual Section Motor Run Round\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: Mars Controls\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MARS-14257\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HEAT CONTROLLER","offers":[{"title":"Default Title","offer_id":51524856611122,"sku":"MARS-14257","price":92.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fcb77f0d1e779d0a59d92e7f5be6e10.jpg?v=1785459746","url":"https:\/\/voomisupply.com\/products\/mars-controls-mars-14257-dual-run-capacitor-80-5-mfd-440-370v","provider":"Voomi Supply","version":"1.0","type":"link"}
