Built with a phenolic composition and a round form factor, this capacitor handles up to 60 starts per hour and operates reliably across a temperature range of -40 degrees F to 149 degrees F (equivalent to -40 to 65 degrees C). Licensed HVAC technicians and refrigeration service professionals install this component as a direct service replacement when a motor exhibits hard-start conditions or fails to start under load.\u003c\/p\u003e\n\u003cp\u003eThe M11055 is suited for residential and commercial AC systems as well as refrigeration equipment where a motor start capacitor is required. It fits typical compressor and fan motor start circuits that operate on 50 or 60 Hz power. The 330-volt rating and 21-25 MFD range make it a commonly stocked service part for technicians handling a broad range of residential split systems, package units, and commercial refrigeration cases. The dual MFD rating accommodates slight variation in motor start requirements within that specification window.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21-25 MFD rating provides the starting capacitance range needed for compatible single-phase motors\u003c\/li\u003e\n  \u003cli\u003e330-volt operating voltage suits standard residential and light commercial circuits\u003c\/li\u003e\n  \u003cli\u003eRated for up to 60 starts per hour for high-cycle applications\u003c\/li\u003e\n  \u003cli\u003ePhenolic composition offers durability in equipment cabinet environments\u003c\/li\u003e\n  \u003cli\u003eRound shape simplifies drop-in replacement in standard capacitor brackets\u003c\/li\u003e\n  \u003cli\u003eWide temperature range of -40 to 65 degrees C for use in varied climates and enclosure conditions\u003c\/li\u003e\n  \u003cli\u003e50\/60 Hz compatible for use across standard North American power systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRecommended for use in residential and commercial AC and refrigeration systems requiring a round motor start capacitor rated at 21-25 MFD and 330 volts.

Disconnect and lock out all power to the unit before servicing. Capacitors store a charge even after power is removed — discharge the capacitor safely using an approved discharge tool or resistor before handling or removing terminals. Follow local electrical codes and the equipment manufacturer's wiring diagram when connecting terminals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitor Type\u003c\/strong\u003e: Motor Start\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMFD Rating\u003c\/strong\u003e: 21-25 MFD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e: 330 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 50\/60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Rated Temperature\u003c\/strong\u003e: 65 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Rated Temperature\u003c\/strong\u003e: -40 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStarts Per Hour\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminals\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComposition\u003c\/strong\u003e: Phenolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended Use\u003c\/strong\u003e: Residential and Commercial AC and Refrigeration\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: RECTORSEAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M11055\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51383720837426,"sku":"M11055","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671035.png?v=1782605493","url":"https:\/\/voomisupply.com\/products\/rectorseal-m11055-motor-start-capacitor-21-25-mfd-330v","provider":"Voomi Supply","version":"1.0","type":"link"}
