It combines two capacitance values in a single round metal can, providing start and run support for both the compressor and fan motor in a split-system air conditioner or heat pump. Rated at 55\/5 microfarads (MFD) and 440 volts, it operates at 50\/60 Hz with a plus or minus 5 percent tolerance. The metal case construction offers durability in the high-heat environment of an outdoor condenser cabinet. Licensed HVAC technicians handle this replacement during seasonal maintenance or when diagnosing weak or failed motor starts.\u003c\/p\u003e\u003cp\u003eThis capacitor is suited for residential and light commercial HVAC applications where a single dual-rated component replaces two separate run capacitors. It fits inside standard condenser unit capacitor brackets and is a common replacement item for aging or failed OEM capacitors in split-system condensers. The 440-volt rating provides a safety margin above the standard 370-volt systems found in most residential equipment, making it a widely accepted cross-compatible option in the field. The round profile and silver metal case are consistent with OEM form factors used across many condenser platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual capacitance rating: 55 MFD and 5 MFD in a single round can\u003c\/li\u003e\n\u003cli\u003e440-volt rating suitable for use in standard residential 370-volt and 440-volt systems\u003c\/li\u003e\n\u003cli\u003e50\/60 Hz operation covers both standard North American and international frequencies\u003c\/li\u003e\n\u003cli\u003ePlus or minus 5 percent capacitance tolerance for reliable motor performance\u003c\/li\u003e\n\u003cli\u003eRound metal case construction resists heat and physical damage inside condenser cabinets\u003c\/li\u003e\n\u003cli\u003eSilver finish round profile matches common OEM capacitor form factors\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\/5 MFD, 440-volt 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, as they retain a charge even after power is removed — discharge the capacitor safely before touching terminals. Verify the MFD ratings and voltage rating of the original capacitor before installing a replacement. Follow all applicable local codes and manufacturer wiring diagrams when reconnecting terminals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 55\/5 MFD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 440 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: plus or minus 5 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Dual\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Height\u003c\/strong\u003e: 4.92 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Import\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DIVERSITECH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4jr0555\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIVERSITECH","offers":[{"title":"Default Title","offer_id":51138453274930,"sku":"4JR0555","price":23.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305534158.png?v=1778256849","url":"https:\/\/voomisupply.com\/products\/diversitech-4jr0555-dual-run-capacitor-55-5-mfd-440v","provider":"Voomi Supply","version":"1.0","type":"link"}
