Marvair 50260 Run Capacitor

The Marvair 50260 Run Capacitor is a high-performance 25 MFD 370VAC electrical component engineered specifically for HVAC capacitor replacement in Marvair wall-mount air conditioners and heat pumps. This round run capacitor is critical for maintaining the proper phase angle in motor windings, ensuring your AC compressor or blower motor operates at peak efficiency while reducing torque pulsation and vibration. Built to professional standards, this motor run capacitor features a self-healing, metallized polypropylene film dielectric housed in a robust, oil-filled aluminum canister to handle the high-current demands and voltage spikes typical in commercial and industrial HVACR applications.

When performing HVAC system diagnostics, a failing capacitor often presents as a bulged top or inability to start the motor under load. The Marvair 50260 serves as a direct OEM replacement part, meeting original equipment specifications for capacitance and voltage. It is designed for continuous duty with a wide operating temperature range from -40°C to 70°C. For contractors and technicians, this unit provides the reliable hvac air conditioning service required to extend the service life of internal system components and optimize energy consumption across the unit's lifecycle.

• Precise Capacitance: Rated at 25 microfarads with a +/- 5% tolerance to ensure exact motor winding current.
• Voltage Compatibility: Rated for 370 VAC, providing a safe operational buffer for standard 208/230V systems.
• Standard Dimensions: Features a 1.75-inch diameter for easy installation within existing mounting straps.
• Rugged Construction: Oil-filled design aids in heat dissipation during high-ambient operation.
• Professional Terminals: Equipped with dual columns of four 1/4-inch quick-connect terminals for flexible wiring.

• Can I use a 440V capacitor to replace a 370V unit? Yes, a higher voltage rating is acceptable as it indicates the peak voltage the capacitor can withstand; however, a 370V unit like the 50260 is the exact match for many Marvair configurations.
• Is the shape important for compatibility? While electrically identical to an oval capacitor of the same rating, the round run capacitor shape is necessary to fit the original factory mounting bracket in most Marvair cabinets.
• How do I confirm this part is failing? Use a multimeter to check for 25 MFD; any reading significantly lower or a visible bulge indicates the part must be replaced to prevent motor overheating.
