Trane SFCAP30440R Capacitor

The Trane SFCAP30440R is a heavy-duty 30 MFD 440V round run capacitor engineered for high-performance motor applications in commercial and residential HVAC systems. Designed as a direct OEM replacement part, this 30 microfarad capacitor ensures precise electrical flow management for compressors and fan motors, maintaining the necessary phase shift for optimal torque and energy efficiency. Constructed with a rugged, non-PCB aluminum casing and dual voltage rating compatibility (370/440V), it is built to withstand demanding thermal environments ranging from -40°F to 158°F. The round can design features standard 1/4-inch quick-connect terminals, facilitating a straightforward swap for technicians during routine maintenance or emergency repairs. By utilizing a genuine Trane capacitor, contractors ensure the system operates within original factory specifications, protecting sensitive motor windings from premature wear and stabilizing voltage supply across the circuit.

Key Benefits

• Safety Certified: Meets UL and EIA standards for internal pressure protection and reliable non-PCB dielectric operation.
• Industrial Build: Engineered for 50/60 Hz cycles, making it suitable for a wide range of global HVACR power specifications.

Common Questions

Can I use a 440V capacitor to replace a 370V unit?
Yes, you can always upgrade to a higher voltage rating like the 440V SFCAP30440R if the microfarad (MFD) rating matches. Using a higher voltage capacity provides a larger safety margin against electrical surges.

What are the signs that my round run capacitor is failing?
Common indicators include a physically swollen or "mushroomed" top, oil leaks around the terminals, or a motor that hums but fails to start. Testing with a multimeter should show a reading within 5% of the 30 microfarads spec.

Is this capacitor compatible with non-Trane systems?
While this is a Trane replacement part, it is a universal 30 MFD 440V round run capacitor that can be used in any brand’s equipment, provided the physical dimensions and electrical specifications match the original component.
