Hartland Controls CAP-35/440R Run Capacitor

The Hartland Controls CAP-35/440R is a high-reliability 35 MFD round run capacitor engineered for demanding HVACR applications. As a veteran-preferred component for condensing units and furnace blower motors, this 35 uF 440V run capacitor is rated for both 370 VAC and 440 VAC systems, providing a versatile solution that simplifies your truck stock. Built to EIA-456 standards, it features a durable unpainted aluminum construction and is designed for an operating life of approximately 60,000 hours under standard conditions. With a +/- 3% capacitance tolerance, it ensures precise electrical performance to maintain optimal motor torque and efficiency. For technicians in the field, the round case design and 1/4-inch quick-connect terminals allow for seamless integration into tight control boxes where space-efficient installation is a priority. Operating within a temperature range of -40°C to 70°C, this motor run capacitor is a dependable choice for ensuring continuous operation in both residential and industrial environments.

• Dual Voltage Compatibility: Rated for both 370V and 440V, allowing for a broader range of HVAC motor replacements with a single part.
• High Precision Performance: Tight +/- 3% tolerance helps prevent motor overheating and ensures stable microfarad output.
• Durable Construction: The oil-filled aluminum housing provides superior heat dissipation and environmental protection.
• Long Service Life: Engineered for up to 60,000 hours of operation, reducing the frequency of call-backs for capacitor failure.

• Can I use a 440V capacitor to replace a 370V? Yes, the 440VAC rating indicates the maximum voltage the insulation can handle; it is a safe and often preferred upgrade for 370V originals.
• What happens if the capacitance (MFD) is off? It is critical to stay within the manufacturer's range. Using a rating significantly higher than 35 microfarads can lead to motor winding damage.
• How do I know when to replace this capacitor? Look for physical signs like capacitor bulging or use a multimeter to check if the MFD reading has dropped more than 5-10% below the 35 uF rating.
