Description
The Trane SFCAP45F10440R is a dual round run capacitor engineered to deliver consistent, reliable electrical performance in residential and commercial HVAC systems. Rated at 45/10 MFD and 440 volts, this dual-section capacitor supports both the compressor and the fan motor simultaneously within a single compact round housing — simplifying installation and reducing the number of components required in the system.
Key Features
- Dual-section design powers both the compressor and condenser fan motor from one unit
- Capacitance rating: 45/10 MFD (microfarads)
- Voltage rating: 440V AC
- Round housing for easy, space-saving installation
- Genuine Trane OEM replacement part (SKU: SFCAP45F10440R)
- Designed for long-lasting, stable capacitance in demanding HVAC environments
Why Run Capacitors Matter
Run capacitors provide the continuous phase shift needed to keep single-phase motors running efficiently. A failed or weak run capacitor leads to hard starting, overheating, reduced motor life, and increased energy consumption. Replacing with a genuine Trane OEM capacitor ensures the correct capacitance and voltage tolerance are maintained, protecting your equipment investment.
Applications
- Trane residential and light commercial air conditioning systems
- Condenser fan motor and compressor motor support
- OEM replacement for compatible Trane equipment
