Description
TradePro 25/5 µF 440 VAC Round Dual Run Capacitor
The TradePro TP-CAP-25/5/440R-A is a 25/5 µF, 440-volt round dual run capacitor for air conditioners, heat pumps and other HVAC equipment. A dual run capacitor serves two motors from one can: the 25 µF side (HERM terminal) runs the compressor and the 5 µF side (FAN terminal) runs the condenser fan motor, with the shared C terminal feeding both.
Replacement basics
- Match the µF rating on both sides to the old capacitor or the equipment label; a tolerance of a few percent is normal
- A 440 V rating safely replaces a 370 V capacitor of the same µF, but never use a 370 V part where 440 V is called for
- Round case; confirm it fits the mounting strap or bracket in the unit
- Turn the power off at the disconnect and discharge the old capacitor before removing it
A weak or failed run capacitor is one of the most common reasons a condenser hums, a fan will not spin, or a compressor runs hot. Keeping a correctly rated spare on the truck saves a second trip.
