Tradepro tp-cap-40/5/440r-a Dual Run Capacitor 40+5 Mfd

Product Description

The TRADEPRO tp-cap-40/5/440r-a is a dual run capacitor rated at 40+5 microfarads (MFD) and 440 volts AC, built in a round form factor for residential and light commercial HVAC applications. This capacitor supports simultaneous operation of both the compressor and the condenser fan motor from a single unit, reducing parts count in the system. It carries UL and CSA recognition, meets EIA-456-A standards, and is protected to 10,000 AFC. Each unit undergoes electrical testing before leaving the factory, making it a reliable OEM-quality replacement for failed or degraded run capacitors.

This capacitor is used in split-system air conditioners, heat pumps, and package units where a dual run capacitor serves the compressor and fan motor circuits together. The round shape fits standard capacitor brackets and retaining straps commonly found in residential condensing units. Licensed HVAC technicians typically install this part during compressor hard-start diagnosis, preventive maintenance, or after confirming capacitor failure with a capacitance meter. It is rated for both 50 Hz and 60 Hz systems, making it suitable across North American and some international equipment.

Key Features

• Dual run capacitor supports compressor and condenser fan motor from a single component
• Rated 40+5 MFD at 440 VAC, also compatible with 370 VAC applications
• UL and CSA recognized for verified safety compliance
• Meets EIA-456-A motor run capacitor standard
• Protected to 10,000 AFC for overcurrent resilience
• Round form factor fits standard condensing unit capacitor mounts

Compatibility

Designed as an OEM-quality replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps that require a round 40+5 MFD 440 VAC dual run capacitor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before opening the electrical compartment, and discharge the existing capacitor fully before handling it, as capacitors can retain a lethal charge after power is removed. Verify the replacement capacitor MFD ratings and voltage rating match the equipment nameplate before installing. Observe local electrical codes and refer to the equipment manufacturer's wiring diagram during reassembly.
