Rectorseal M12075 Dual Run Capacitor 50/3 Mfd 370V

Product Description

The RECTORSEAL M12075 is a dual run capacitor rated at 50/3 microfarads (MFD) and 370 volts, designed for use in single-phase HVAC systems. Run capacitors provide the continuous phase shift needed to keep compressor and fan motors running efficiently after startup. This round-style capacitor replaces failed or degraded units in split-system air conditioners and heat pumps. HVAC technicians install this part during routine capacitor replacement service calls. The compact round form factor fits standard capacitor brackets in most residential condensing units.

This capacitor is suited for residential and light commercial HVAC condensing unit applications where a single round dual-rated capacitor serves both the compressor and the condenser fan motor. The 50 MFD winding supports the compressor load while the 3 MFD winding supports the fan motor. The 370-volt rating meets the operating requirements of standard single-phase compressor and fan motor circuits found in split-system cooling and heat pump equipment.

Key Features

• Dual run capacitor: 50 MFD for compressor, 3 MFD for condenser fan motor
• 370-volt AC rating for standard single-phase HVAC circuits
• Round form factor fits common condensing unit capacitor brackets
• Compact footprint: 2.5 inches wide by 3.625 inches tall

Compatibility

Designed as an OEM-style replacement dual run capacitor for single-phase residential and light commercial air conditioning and heat pump condensing units requiring a 50/3 MFD, 370-volt round capacitor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always disconnect and lock out power to the condensing unit at the disconnect box before servicing capacitors. Capacitors store a lethal electrical charge even after power is removed — discharge the capacitor through a resistive load before handling. Verify that replacement MFD ratings and voltage rating match the existing unit nameplate before installing.
