Run Capacitor, Round, 50/12.5 MFD, 440/370

Mars 12253 Dual Section Motor Run Capacitor – 50/12.5 MFD, 440V The Mars 12253 is a dual-section run capacitor designed for continuous-duty motor operation in HVAC systems. It provides two capacitance values—50 and 12.5 microfarads—at a 440V AC rating, making it suitable for applications requiring both compressor and fan motor support in a single unit. Constructed with an aluminum round canister and oil-filled dielectric, the unit is hermetically sealed to protect against environmental conditions common in rooftop and outdoor condenser installations. The capacitor is equipped with standard ¼" quick-connect terminals for streamlined service replacement and OEM compatibility. Specifications: Capacitance: 50/12.5 microfarads (MFD) Voltage Rating: 440V AC Shape: Round Terminals: Dual with ¼" male quick-connect blades Construction: Aluminum case, oil-filled, hermetically sealed Frequency: 50/60 Hz Compliance: UL recognized component; RoHS compliant Key Application Details: Suitable for dual-motor capacitor requirements in HVAC condenser units Designed for use in permanent split capacitor (PSC) motors Compatible with a wide range of residential and light commercial HVAC systems Intended for professional installation to ensure correct sizing and safe operation Contractor-Focused Notes: Dual-section design minimizes component count and simplifies service calls Long-life construction with corrosion-resistant casing ensures reliability under high ambient conditions Rated for consistent capacitance tolerance across temperature ranges to maintain system performance
