Hartland Controls CAP-70/7.5/440R Run Capacitor

The Hartland Controls CAP-70/7.5/440R Run Capacitor is a high-duty 70/7.5 microfarad dual run capacitor engineered for demanding HVACR applications requiring simultaneous support for both the compressor (herm) and fan motor. Rated for 370/440Vac, this round dual run capacitor provides a versatile drop-in solution for 440V systems while remaining fully backward compatible with 370V circuits. As a veteran-grade CBB65 HVAC capacitor, it is built to handle the continuous voltage spikes and thermal stress typical of 5-ton condenser units and commercial refrigeration packages.

The rugged aluminum casing and non-PCB oil-filled dielectric construction ensure consistent capacitance stability across the -40?C to +70?C operating range. Contractors will find the standard 1/4-inch male quick-connect terminals simplify field replacement, especially in tight control boxes where the round capacitor footprint is preferred. With a 10,000 AFC (Available Fault Current) safety rating, the CAP-70/7.5/440R is a reliable OEM replacement capacitor that restores motor torque and maintains power factor efficiency in high-ambient environments.

• Dual-Purpose Design: Consolidates 70 MFD and 7.5 MFD values into a single canister to drive both the compressor and fan.
• Universal Voltage Rating: Rated for 440VAC, allowing it to safely replace both 370V and 440V capacitors without derating.
• Extreme Durability: Metal-cased and oil-filled to provide superior heat dissipation and internal pressure protection.
• Safety Certified: Built to EIA-456-A standards with a 10,000 AFC rating for reliable circuit protection.

Can I use a 440V capacitor if my old one was 370V?
Yes. In the field, a higher voltage rating (440V) is a standard upgrade for a 370V capacitor as it offers a higher insulation threshold. Never substitute a 370V capacitor into a 440V circuit.

What are the signs of a failing CAP-70/7.5/440R?
Common failure indicators include a "mushroomed" or bulging top, fluid leaks, or an audible humming from the compressor without a start. Always verify the capacitance with a multimeter before installing.

Is the round-to-oval conversion possible?
Technically, yes?as long as the MFD and voltage ratings match exactly. However, this round physical profile is specifically intended for standard circular mounting brackets found in most modern condensers.
