Trane SFCAP45D5440R Dual Run Capacitor 45/5 MFD 440V Round

The Trane SFCAP45D5440R is a dual run capacitor designed for HVAC applications, providing reliable performance for both compressor and fan motor circuits. This OEM replacement capacitor features dual capacitance ratings of 45 MFD and 5 MFD at 440 volts, making it suitable for residential and light commercial air conditioning and heat pump systems.

Key Specifications:

• Dual capacitance: 45 MFD (microfarads) and 5 MFD
• Voltage rating: 440 VAC
• Round metal housing for durability and heat dissipation
• Replaces Trane part number CPT00656
• Temperature rated for HVAC applications
• Universal mounting bracket compatible with standard installations

This genuine Trane capacitor is engineered to meet OEM specifications for fit, form, and function. Dual run capacitors are essential components that provide the necessary electrical phase shift to start and run both the compressor and condenser fan motor efficiently. The 45 MFD side typically supports the compressor circuit, while the 5 MFD side powers the fan motor, though always verify your equipment specifications before installation.

Installation Notes: Always discharge capacitors before handling, disconnect power to the unit, and ensure proper terminal connections (HERM, FAN, and COM terminals). Replace with same voltage and MFD ratings to ensure proper system operation and longevity.
