Run capacitors maintain the phase shift needed to keep permanent split capacitor (PSC) motors running efficiently after startup. This oval form factor fits the mounting hardware found in most residential and light commercial condensing units and air handlers. HVAC technicians reach for this part when diagnosing a compressor or condenser fan motor that runs sluggishly, overheats, or fails to maintain speed under load.\u003c\/p\u003e\u003cp\u003eThe MARS 12949 is a direct replacement run capacitor suited to residential and light commercial HVAC applications. It is commonly installed in condensing units, heat pumps, and air handling equipment where a single 50 MFD, 440-volt oval capacitor is required. The 440-volt rating provides a safe operating margin in systems that nominally run on 370-volt or 440-volt circuits, making it a versatile stock item for field service technicians.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e50 MFD capacitance rating for PSC motor phase-shift support\u003c\/li\u003e\n\u003cli\u003e440-volt rating suitable for both 370V and 440V nominal circuits\u003c\/li\u003e\n\u003cli\u003eOval form factor fits standard HVAC capacitor brackets and mounting clips\u003c\/li\u003e\n\u003cli\u003eSingle-unit pack  -  one capacitor per package, no splitting required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement oval run capacitor for residential and light commercial HVAC systems requiring a 50 MFD, 440-volt single capacitor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eRun capacitors must be installed by a qualified HVAC technician. Always disconnect and lock out power to the unit before handling any capacitor, and discharge the capacitor using an appropriate resistive discharge tool before touching terminals  -  capacitors retain a lethal charge even after power is removed. Verify the MFD rating, voltage rating, and terminal configuration match the original before installation. Follow all applicable local electrical codes and manufacturer wiring diagrams during replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 50 MFD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 440 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Oval\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: 12949\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARS (MOTORS \u0026 ARMATURES)","offers":[{"title":"Default Title","offer_id":68088976572722,"sku":"12949","price":28.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee02e97452bae835af5c64c8b77d9864_33497bb9-e6f0-485e-badd-88934cff665a.jpg?v=1793204043","url":"https:\/\/voomisupply.com\/products\/mars-12949-oval-run-capacitor-50-mfd-440v","provider":"Voomi Supply","version":"1.0","type":"link"}
