Supco lcd70+7.5x440r Dual Run Capacitor 70+7.5 Mfd 440V

Product Description

The SUPCO lcd70+7.5x440r is a round dual run capacitor rated at 70 plus 7.5 microfarads (MFD) and 370/440 volts AC. It is designed to start and run both the compressor and fan motor in a single unit, reducing the component count in an HVAC system. The capacitor measures 2.5 inches in diameter by 4.33 inches in length and is built with thick polypropylene foil construction to handle elevated operating temperatures. HVAC technicians install this part as a direct replacement in residential and light commercial air conditioning and heat pump systems.

This capacitor fits applications where a single round dual run unit serves both the compressor and the condenser fan motor. The 370/440 volt dual-rated design makes it compatible with standard single-phase motor circuits found in split-system air conditioners and heat pumps. Its tolerance of plus or minus 5 percent MFD and an operating temperature range of -40 to 85 degrees F make it well suited for outdoor condensing unit installations in a wide range of climates.

Key Features

• Dual run design supports compressor and fan motor from a single capacitor
• Rated 70 plus 7.5 MFD with plus or minus 5 percent tolerance
• 370/440 volt AC dual-rated for broad single-phase circuit compatibility
• Thick polypropylene foil construction for high-temperature endurance
• Operating range of -40 to 85 degrees F suits outdoor condensing unit environments
• UL and VDE listed for safety and performance compliance

Compatibility

Designed as an OEM-style replacement dual run capacitor for single-phase residential and light commercial HVAC compressors and condenser fan motors requiring a 70 plus 7.5 MFD, 370/440 volt round capacitor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before handling capacitors, as they store a charge that can cause serious injury even after power is removed — discharge the capacitor safely before removal. Verify MFD ratings and voltage rating match the existing capacitor or OEM specification before installing. Secure the capacitor in its mounting bracket and ensure all terminals are tight and properly insulated after connection.
