Hartland Controls CAP-35/5/440 Run Capacitor

When you're out on a job and find a compressor struggling to turn over or a condenser fan that only spins with a manual nudge, the Hartland Controls CAP-35/5/440 Run Capacitor is the reliable, professional-grade swap you need. This 35/5 microfarad dual run capacitor is built to handle the rigorous demands of residential and commercial HVACR systems. Rated for 370/440VAC, it offers the overhead necessary to prevent dielectric breakdown in high-heat environments. The oval dual run capacitor design ensures a compact footprint, fitting easily into tight control boxes where round cans might struggle for clearance. With high-quality aluminum oil-filled construction and an internal 10,000 AFC protection bridge, this component provides the stability required for optimal motor torque and efficiency. It is designed and manufactured in accordance with UL 810 standards, making it a staple for any technicianÆs truck stock when dealing with failed start windings or out-of-tolerance capacitance readings.

• Dual-Rated Versatility: Provides dedicated 35 MFD for the compressor and 5 MFD for the fan motor in a single, space-saving housing.
• Universal Voltage Compliance: Rated for both 370V and 440V applications, simplifying inventory for varied field requirements.
• Industry-Standard Safety: Features a built-in internal protection bridge and 10,000 AFC rating to ensure safe interruption in the event of a fault.
• Contractor-Grade Terminals: Equipped with standard 0.250-inch quick-connect terminals for fast, secure wiring.
• Wide Operating Temperature: Engineered to maintain precise capacitance tolerance across a broad thermal range, from -40°C to 70°C.

Can I use this 440V capacitor to replace a 370V unit?
Yes. You can always go up in voltage rating, but never down. This 440VAC capacitor provides better dielectric strength and longevity when replacing a 370VAC part.

How do I identify the correct wiring terminals?
The terminals are clearly marked: 'C' for Common (typically 4 prongs), 'HERM' for the compressor (3 prongs), and 'FAN' for the condenser fan (2 prongs).

What are the signs this capacitor has failed?
Look for physical bulging of the casing, oil leaks, or a compressor that hums but fails to start. If your multimeter shows more than a 6% deviation from the 35 or 5 MFD ratings, it is time for a replacement.
