Ferguson Enterprises CAP050400440RTP Dual Run Capacitor

Product Description

The FERGUSON ENTERPRISES CAP050400440RTP is a dual run capacitor designed to support motor starting and running in residential and light commercial HVAC systems. Rated at 40/5 microfarads (MFD) and 440 volts AC, this round-style capacitor serves both the compressor and the fan motor from a single unit, reducing component count in the electrical compartment. Licensed HVAC technicians install this type of capacitor as a direct replacement when a failed or weak capacitor causes hard-start conditions, slow motor startup, or compressor drop-out. Its dual-section design simplifies the wiring layout compared to two separate capacitors.

This dual run capacitor is suited for split-system air conditioners, heat pumps, and package units where a single capacitor serves both the compressor motor and the condenser fan motor. The 40/5 MFD rating covers a common configuration found in residential tonnage equipment, and the 440-volt rating provides compatibility with standard single-phase 240-volt HVAC systems while offering a voltage margin above the 370-volt minimum often encountered in older equipment.

Key Features

• Dual-section design supports compressor (40 MFD) and condenser fan motor (5 MFD) in one unit
• Rated at 440 volts AC for use in standard single-phase HVAC applications
• Round form factor fits standard capacitor brackets and mounting clips
• Higher 440-volt rating provides operating headroom compared to 370-volt capacitors
• Single replacement unit simplifies serviceability in the field

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial HVAC systems requiring a round 40/5 MFD 440-volt dual run capacitor.

Installation Notes

A licensed HVAC technician should perform capacitor replacement. Disconnect and lock out all power to the unit before opening the electrical compartment, and discharge the existing capacitor fully before handling or removing wiring. Verify the replacement MFD ratings and voltage rating match the equipment nameplate before installation. Follow all applicable local electrical codes and manufacturer service instructions during replacement.
