Hartland Controls CAP-45/440R Run Capacitor
The Hartland Controls CAP-45/440R is a high-performance 45 MFD 440V round run capacitor engineered for continuous-duty applications in demanding HVACR environments. Designed to maintain stable capacitance for PSC (permanent split capacitor) motors, this unit is a standard compressor run capacitor for residential and commercial condensing units. With a voltage rating of 370/440 Vac, it offers full backward compatibility for 370V systems while providing superior dielectric strength and thermal stability. The aluminum oil-filled casing is built to the EIA-456-A industry standard, ensuring consistent torque and power factor correction under heavy load cycles. Featuring a 10,000 AFC safety pressure interrupter and an operating temperature range of -40°C to +70°C, this 45 microfarad motor capacitor is a reliable choice for professional technicians performing field replacements on blower motors and refrigeration compressors.
Key Benefits- Universal Compatibility: Rated for both 370V and 440V applications, simplifying truck stock for diverse service calls.
- Enhanced Safety: Internal UL-recognized pressure sensitive interrupter disconnects the capacitor at end-of-life to prevent case rupture.
- High Duty Cycle: Engineered for 60,000 hours of operational life with a low-loss, self-healing metalized polypropylene film.
- Environmental Resilience: Features non-PCB oil and a corrosion-resistant unpainted aluminum finish for long-term durability in outdoor cabinets.
Can I use a 440V capacitor to replace a 370V capacitor?
Yes. For run capacitors, you can always increase the voltage rating (e.g., using a 440V to replace a 370V), but you must never use a lower voltage rating than the original component.
How do I verify the capacitance needed for my motor?
Always check the motor nameplate. A 45 MFD rating must be matched exactly; using an incorrect microfarad rating can lead to overheating and premature motor failure.
What is the benefit of a round versus an oval capacitor?
The shape is purely physical. As long as the 45 microfarad and voltage ratings match, a round capacitor is electrically identical to an oval one, provided it fits the mounting strap.
