Copeland 914-0037-40 Run Capacitor

The Copeland 914-0037-40 Run Capacitor is a high-grade electrical component engineered for continuous duty in single-phase motor applications. Rated at 50 MFD 370VAC, this round run capacitor provides the precise phase shift required to optimize HVAC compressor performance and maintain high torque during operation. Constructed with a durable aluminum casing and oil-filled for superior heat dissipation, it is designed to withstand the rigorous duty cycles of refrigeration systems and industrial air conditioning units. As a direct Copeland replacement part, it ensures seamless compatibility with specified OEM motor configurations, preventing the winding overheating and energy loss associated with using mismatched capacitance levels. For field technicians, the round run capacitor design with standard 1/4-inch quick-connect terminals allows for rapid installation in tight control boxes.

Key Benefits:

• Stable 50 microfarad capacitance ensures efficient motor starting and running.
• Robust 370V AC rating supports high-voltage industrial and residential electrical demands.
• Optimizes energy consumption and extends AC motor service life by maintaining a consistent magnetic field.
• Oil-filled round capacitor construction provides reliable thermal stability in demanding environments.

Common Questions:

Can I use a 440V capacitor to replace this 370V model?
Yes, you can substitute a higher voltage rating (e.g., 440VAC) for this 370VAC part as long as the 50 MFD rating is identical. Never use a capacitor with a lower voltage rating than the original equipment specifies.

Does the shape of the capacitor matter for performance?
While the 914-0037-40 is a round run capacitor, the electrical performance depends on the MFD and voltage. Ensure the physical dimensions fit within your current mounting bracket before switching from an oval to a round profile.

How do I know if my compressor run capacitor is failing?
Common indicators include a humming motor that fails to start, physical bulging or leaking from the capacitor casing, or a capacitance reading outside of the standard +/- 5% to 10% tolerance range when measured with a multimeter.
