Dual run capacitors serve two motor windings simultaneously, supporting both the compressor and the condenser fan motor from a single unit. This reduces cabinet space requirements compared to two separate capacitors. The round form factor is a standard configuration widely stocked by HVAC technicians for service and replacement work. Licensed HVAC technicians are the typical installers for this component.\u003c\/p\u003e\u003cp\u003eThe MARS 12228 is suited for split-system air conditioners, heat pumps, and packaged units that use a shared capacitor for the compressor and condenser fan motor. The 370-volt rating makes it appropriate for standard residential single-phase systems operating on 208\/240-volt circuits. The round case design fits common capacitor mounting brackets found in most outdoor condensing units, simplifying field replacement during seasonal maintenance or emergency service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual run capacitor supports compressor and condenser fan motor from a single component\u003c\/li\u003e\n\u003cli\u003e30\/10 MFD rating provides correct capacitance for two-winding single-phase applications\u003c\/li\u003e\n\u003cli\u003e370-volt rating suitable for 208\/240-volt residential and light commercial systems\u003c\/li\u003e\n\u003cli\u003eRound case form factor fits standard condensing unit mounting hardware\u003c\/li\u003e\n\u003cli\u003eCompact design preserves cabinet space versus two discrete capacitors\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 30\/10 MFD, 370-volt round capacitor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDual run capacitors must be installed by a qualified, licensed HVAC technician. Disconnect and lock out all power to the unit before handling any capacitor, as capacitors retain a dangerous charge even after power is removed — discharge the capacitor safely using an approved discharge tool before touching terminals. Verify that replacement capacitor ratings match the original equipment nameplate specifications before installation. Follow all applicable local electrical codes and manufacturer service guidelines during replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 30\/10 MFD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 370 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Dual Run Capacitor\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12228\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARS","offers":[{"title":"Default Title","offer_id":51468205261106,"sku":"12228","price":39.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12228.jpg?v=1783914384","url":"https:\/\/voomisupply.com\/products\/mars-12228-dual-run-capacitor-30-10-mfd-370v","provider":"Voomi Supply","version":"1.0","type":"link"}
