Packard POC17.5 Run Capacitor

The Packard POC17.5 is a professional-grade 17.5 MFD 370V Oval Run Capacitor engineered for continuous duty in residential and light commercial HVAC compressor and fan motor circuits. This motor run capacitor features metalized polypropylene film technology, providing self-restoration capabilities that preserve circuit integrity if a dielectric breakdown occurs. Built to EIA-456-A standards, the POC17.5 utilizes a UL-approved pressure-sensitive interrupter designed to safely disconnect the unit at the end of its 60,000-hour service life, preventing case rupture.

For inventory management and field service, this oval capacitor is a direct 17.5 microfarad replacement for 370VAC applications and can safely substitute for lower-voltage units if necessary. The corrosion-resistant aluminum casing and environmentally friendly dielectric oil ensure stable heat transfer and consistent capacitance tolerance in high-ambient condenser environments. Ensure you verify the 2-inch width and 1.25-inch depth for bracket compatibility before installation.

• EIA-456-A Compliant: Rigorously tested for 60,000 duty hours to ensure long-term reliability in demand-heavy HVAC systems.
• Self-Healing Technology: Metalized film construction allows the capacitor to recover from internal surges, maintaining precise 17.5 MFD output.
• Internal Safety Interrupter: UL-approved mechanism removes the capacitor from the circuit under fault conditions, protecting the blower motor or compressor.
• Broad Compatibility: Fits standard oval mounting brackets used by major OEM brands in air conditioning and refrigeration equipment.

Can I use a 440V capacitor to replace a 370V POC17.5?
Yes. While a 370V capacitor cannot replace a 440V unit, you can always up-rate the voltage. The capacitance (17.5 MFD) must remain identical to the motor's nameplate requirements.

Does the orientation of the oval shape matter during installation?
The electrical performance is identical regardless of orientation, but ensuring a snug fit in the strap bracket is critical to prevent vibration-induced lead failure.

What are the symptoms of a failing 17.5 MFD run capacitor?
Watch for high amperage draw, "hard starting" or humming from the motor, and physical indicators like bulging terminal caps or leaking dielectric fluid.
