Oval Run Capacitor 20 MFD 370 VAC

The Supco CR20X370 is an oval run capacitor rated at 20 microfarads and 370 volts AC. It is built for continuous duty in HVAC motor circuits such as condenser fans, furnace blowers, refrigeration compressors and air-conditioning compressors. The drawn steel case measures 2.8125 by 2.5625 by 1.75 inches and carries UL and VDE agency marks.

Suits technicians replacing Packard POC20

This part matches the capacitance and voltage of those common replacements and fits the same oval mounting footprint. Installers who need a different microfarad value, a higher voltage rating or a round canister style should select another model.

Capacitance tolerance of plus or minus five percent

The 20 MFD rating holds within a tight five percent window, ensuring the motor receives the correct phase-shift current for efficient starting and running. A wider tolerance would risk reduced torque, overheating or premature capacitor failure.

Questions about this item

What motor voltage rating does the 370 VAC capacitor need to match?

The capacitor is rated for 370 VAC, so the motor’s nameplate voltage must be 370 VAC or lower.

Will the oval 2.8125 x 2.5625 inch case fit the same bracket as my old Packard POC20?

Yes, the CR20X370 is listed as a direct replacement for the Packard POC20 and shares the same oval dimensions.

How can I confirm the capacitor is healthy after wiring it to the compressor?

Measure capacitance with a multimeter; a reading within ±5 % of 20 MFD and no short between terminals or to the case shows it is working.
