Hartland Controls CAP-17.5/440 Run Capacitor
When you're out in the field and a blower or compressor cycle fails, the Hartland Controls CAP-17.5/440 Run Capacitor is a standard replacement part that keeps the system from drawing excessive current. This 17.5 MFD 440V oval run capacitor is engineered to meet EIA-456 standards, ensuring high-performance reliability in demanding HVACR environments. Because it is dual voltage rated for 370/440 VAC, you can use it to replace either a 370V or 440V unit, reducing the variety of stocked parts on your truck. Internally, it utilizes a metalized polypropylene film dielectric protected by a proprietary biodegradable oil, which aids in heat dissipation and internal pressure management. The unpainted aluminum housing and steel cover are designed to fit standard oval brackets. For the technician, this means stable microfarad tolerance of ±3% and an operational life rated up to 60,000 hours, significantly reducing callbacks related to motor winding overheating or starting torque failures.
Key Benefits- Universal Voltage Compatibility: The 370/440 VAC rating makes this a versatile stock item for various commercial and residential motors.
- Precision Tolerance: Features a ±3% capacitance tolerance, providing tighter operational control than generic ±6% alternatives.
- High-Grade Construction: Built with heavy-edged metalized film and an integrated anti-explosion safety switch for robust circuit protection.
- Optimized Heat Transfer: The non-PCB biodegradable oil and aluminum case ensure the component maintains its rating even in high-ambient condenser sections.
Can I use a 440V capacitor to replace a 370V capacitor?
Yes. You can always go up in voltage rating as it offers higher dielectric strength. However, you must never go below the voltage rating specified on the motor nameplate.
What happens if my microfarad (MFD) reading is outside the ±3% range?
If the 17.5 uF capacitor measures below 16.9 or above 18.0 MFD, it should be replaced immediately. Operating outside this range increases motor winding temperature and can lead to premature compressor failure.
Are all oval run capacitors the same size?
No. While this is a standard oval motor run capacitor, physical dimensions vary by manufacturer. Always verify the base dimensions (typically 2.75" x 1.75") to ensure it fits the existing mounting strap.
