Hartland Controls CAP-80/5/440 Run Capacitor

The Hartland Controls CAP-80/5/440 is a heavy-duty 80/5 microfarad dual run capacitor engineered for high-demand HVACR applications. This 370/440Vac oval capacitor is designed to provide the necessary phase shift for both the compressor and the condenser fan motor, ensuring efficient torque and power factor performance. Built with metallized polypropylene film and a dielectric oil-filled aluminum case, it effectively dissipates heat to maintain stability in extreme environments ranging from -40°C to 70°C. As a veteran-grade motor run capacitor, it features an internal 10,000 AFC protection bridge to safely interrupt the circuit in the event of excessive internal pressure. The dual capacitance 80+5 uF rating makes it a standard replacement for many large-tonnage residential and commercial air conditioning units. For technicians, the triple-terminal header clearly identifies "Herm," "Fan," and "C" connections for streamlined wiring and field reliability.

• Dual Rated Performance: Operates at both 370V and 440V, reducing the need to carry multiple SKUs on the service truck.
• Durable Construction: Housed in a seamless, unpainted aluminum oval case for superior corrosion resistance and thermal management.
• Internal Safety Bridge: UL 810 recognized pressure-sensitive interrupter prevents case rupture during end-of-life failure.
• Standardized Terminals: Features .250-inch quick-connect terminals for secure, low-resistance electrical connections.
• EIA RS-456 Compliant: Manufactured to meet rigorous industry standards for duty cycle and electrical performance.

Can an oval capacitor replace a round capacitor?
Yes, provided the microfarad (uF) and voltage (Vac) ratings match. However, the oval dual run capacitor footprint may require a different mounting strap or bracket than its round counterpart.

Is 440V compatible with a 370V system?
Absolutely. You can always use a higher-voltage capacitor (440V) to replace a lower-voltage one (370V), but never the reverse. Using a 440V rated unit typically offers better longevity due to its higher dielectric strength.

How do I identify a failing 80/5 dual capacitor?
Common indicators include a bulged top, an AC unit hum without the compressor starting, or the fan failing to spin. For an accurate diagnosis, use a multimeter to verify the 80+5 MFD capacitance within its +/- 3% or 5% tolerance.
