Hartland Controls CAP-15/5/440R Run Capacitor

The Hartland Controls CAP-15/5/440R Run Capacitor is a high-spec 15/5 MFD dual run capacitor designed for demanding HVACR applications. This round dual motor run capacitor provides reliable phase-shift for both the compressor and the fan motor, featuring a dual-rated 370/440 VAC threshold. This makes it a versatile stock item for technicians, as it safely supersedes 370V components while meeting the insulation requirements of 440V systems. Built in accordance with EIA-456 standards, it is the direct replacement for CAP050150440RSP and is compatible with major OEM equipment brands requiring a 15+5 microfarad configuration. The unpainted aluminum housing facilitates effective heat dissipation, ensuring stable capacitance across an operating temperature range of -40°C to 70°C. With 1/4" quick-connect terminals and a ±3% capacitance tolerance, this unit ensures precise motor torque and amperage draws in residential and light commercial condensers.

Technical Benefits for Contractors:

• Multi-Voltage Compatibility: Rated for both 370V and 440V, allowing for SKU consolidation on service trucks without compromising dielectric strength.
• EIA-456 Compliant: Engineered for professional-grade reliability, ensuring consistent performance in high-duty cycle compressors.
• Precision Tolerance: A ±3% capacitance tolerance provides more accurate motor phasing than standard ±5% or ±10% alternatives.
• Direct OEM Replacement: Drop-in compatibility for CAP050150440RSP, reducing troubleshooting and installation time in the field.
• Robust Construction: Features a pressure-sensitive interrupter and an internal 10,000 AFC safety rating for secure operation in extreme conditions.

Common Technical Questions:

Can I use a 440V capacitor to replace a 370V capacitor?
Yes. Using a 440 volt dual run capacitor in a system originally equipped with a 370V part is a safe upgrade. The voltage rating indicates the maximum electrical stress the capacitor can handle; a higher rating provides a greater margin of safety.

What does the 15/5 MFD rating signify?
This is a dual-rated part. The 15 MFD terminal (HERM) supports the compressor, while the 5 MFD terminal (FAN) supports the outdoor fan motor. Both circuits share the Common (C) terminal.

How do I know if the CAP-15/5/440R is the right fit?
Verify the microfarad (µF) requirements on your motor's nameplate. If it specifies 15+5 µF and requires a round housing for the mounting strap, this capacitor is the correct replacement regardless of whether the original was 370V or 440V.
