Run Start Capacitor, Round, 25/7.5 MFD, 440/370

Mars 12779 – Dual Run Capacitor, 25/7.5 MFD, 370/440V, Round Case The Mars 12779 dual run capacitor is rated at 25/7.5 microfarads (MFD) with a voltage tolerance of 370/440 VAC. It supports both compressor and condenser fan motors in HVAC systems utilizing permanent split capacitor (PSC) motors. The round aluminum case provides a compact, durable enclosure for use in residential and light commercial air conditioning and heat pump systems. This component is designed to maintain motor efficiency, deliver consistent startup performance, and help reduce system strain during operation. Technical Specifications Capacitance: 25/7.5 MFD (dual rating) Voltage: 370/440 VAC Frequency: 50/60 Hz Shape: Round Case Material: Aluminum Dielectric Fluid: Oil-filled, non-PCB Interrupter: Pressure-sensitive internal safety switch Terminal Configuration: Dual quick-connect terminals Application For use with HVAC systems requiring dual motor capacitor support Common in split-system A/C units and heat pumps Compatible with systems designed for 370 or 440 volt applications Installation Notes Always disconnect power before service. Verify system capacitance and voltage requirements match the capacitor being installed. Follow proper procedures for discharging the old capacitor and securing the replacement with proper insulation and mounting support. Installation should be performed by qualified HVAC personnel in accordance with local electrical codes.
