Packard POC25 Run Capacitor

As an HVACR professional, you know that a dependable 25 MFD 370V Oval Run Capacitor is a core service truck staple for keeping single-phase motors and compressors in peak operating condition. The Packard POC25 is engineered to meet the stringent EIA-456A industry standards, providing the consistent phase shift required for high-torque startups and efficient motor operation. Built with metalized polypropylene film technology, this unit features a self-healing dielectric that automatically isolates breakdown sites to prevent total failure. Its oval form factor ensures a drop-in fit for standard HVAC mounting brackets across multiple residential and commercial applications. To enhance safety, the Packard POC25 Run Capacitor includes an internal, pressure-sensitive interrupter designed to remove the component from the circuit safely at the end of its 60,000-hour service life. This non-PCB, oil-filled run capacitor provides superior heat dissipation and is rated for operation up to 185°F, making it a reliable HVAC motor capacitor replacement for demanding field environments.

Key Benefits

• Metalized Polypropylene Film: Features self-restoring properties to maintain performance in the event of internal voltage breakdowns.
• High Heat Tolerance: Rated for continuous operation up to 70°C (185°F) with superior heat transfer through specialized dielectric oil.
• Enhanced Safety: Built-in UL-approved pressure-sensitive interrupter provides a fail-safe end-of-life circuit disconnection.
• Universal Compatibility: Standard 25 microfarad 370V rating and oval chassis allow for seamless AC capacitor cross-reference and replacement.

Common Questions

Can I use a 440V capacitor to replace a 370V 25 MFD run capacitor?
Yes. While the microfarad (MFD) rating must match the OEM motor specifications exactly (25 MFD), you can always use a capacitor with a higher voltage rating. A 440V unit can handle 370V circuits without issue, but never install a lower-rated voltage capacitor, as it will lead to premature failure or safety risks.

What are the signs that my Packard POC25 needs replacement?
Visible bulging of the top casing, oil leaks, or a compressor/fan motor that hums but fails to start are primary indicators of a failed run capacitor. You should also verify the health of the part by testing with a multimeter set to the capacitance (MFD) range; if the reading is more than 10% below the 25 MFD rating, replace it immediately.

Does the orientation of the capacitor matter during installation?
The Packard POC25 can be mounted in any orientation within the terminal box. However, ensure the terminals are properly seated and clear of any metal debris. If the original bracket is loose, use a standard mounting strap to secure the oval chassis and prevent vibration damage.
