Trane SFCAP40D5440R Dual Run Capacitor 40/5 MFD 440V Round

The Trane SFCAP40D5440R is a dual run capacitor designed for HVAC applications, providing reliable performance for both compressor and fan motor circuits. This round capacitor features a 40/5 microfarad (MFD) rating at 440 volts, making it suitable for residential and light commercial air conditioning systems.

Key Specifications:

• Dual capacitance: 40 MFD and 5 MFD in a single unit
• Voltage rating: 440 VAC
• Round metal case construction for durability
• Does not include a bleed resistor (resistorless design)
• Direct replacement for Trane CPT00668
• Standard terminal configuration for easy installation

Dual run capacitors like this unit help start and run both the compressor and fan motor in air conditioning and heat pump systems. The larger 40 MFD section typically supports the compressor, while the smaller 5 MFD section powers the condenser fan motor. This genuine Trane replacement part ensures proper capacitance values and voltage ratings for optimal system performance and longevity.
