Hartland Controls CAP-30/440R Run Capacitor

The Hartland Controls CAP-30/440R is a heavy-duty 30 MFD round run capacitor engineered for continuous duty in residential and commercial HVACR systems. Built to EIA-456 standards, this 370/440V run capacitor provides essential phase-shift current to fan motors and compressors, ensuring high power factor performance and efficient motor torque. Its dual-voltage rating allows for versatile field application, functioning as a reliable HVAC replacement capacitor for units requiring either 370 VAC or 440 VAC. The unpainted aluminum casing and oil-filled construction are designed for optimal heat dissipation and internal pressure protection. Field technicians can utilize this component as a direct replacement for CPT0241, CPT0321, and SFCAP30440R, providing a seamless fit for round-can mounting straps. With a ±3% capacitance tolerance and an operating temperature range of -40°C to 70°C, this 50/60 Hz component maintains stable capacitance under high-stress cycling.

Common Questions

Can this 440V capacitor replace a 370V rated capacitor?
Yes. In HVACR applications, you can always use a capacitor with a higher voltage rating than the original, as long as the microfarad (MFD/µF) rating matches. The 440V rating indicates the maximum dielectric strength.

What does the ±3% tolerance mean for motor performance?
This tight tolerance ensures the 30 microfarad output remains within a precise range, which is critical for maintaining the correct phase angle and preventing motor overheating or premature winding failure.

Is the CAP-30/440R compatible with both 50Hz and 60Hz systems?
Yes, this round run capacitor is rated for 50/60 Hz frequency, making it suitable for standard domestic grids and international equipment setups.
