The TRADEPRO tp-cap-30/440usar is a round single-run capacitor rated at 30 microfarads (MFD) and 440 volts, manufactured in the USA. Run capacitors provide the continuous phase-shifted current that keeps single-phase compressor and fan motors running efficiently after startup. This unit is built to standard round-can dimensions, making it a direct-fit replacement in a wide range of residential and light commercial HVAC equipment. Licensed HVAC technicians handle installation as part of routine compressor or condenser fan motor service.
This capacitor is suited for use in central air conditioners, heat pumps, and condenser units that require a single 30 MFD run capacitor at 440 volts AC. The 440-volt rating provides margin above the standard 370-volt systems, meeting the requirements of both 370 V and 440 V rated equipment. It is commonly installed in the condensing unit control compartment alongside the contactor and other electrical components.
Designed as an OEM-style replacement round run capacitor for residential and light commercial HVAC condensing units requiring a 30 MFD, 440-volt single capacitor.
Installation must be performed by a licensed HVAC technician in accordance with applicable local codes and the equipment manufacturer's service instructions. Always disconnect and lock out power to the unit before accessing the control compartment, and discharge the existing capacitor fully before handling — capacitors retain a dangerous charge even after power is removed. Verify the MFD rating and voltage rating match the original capacitor before connecting. Secure the capacitor in the mounting bracket and confirm all terminals are tight before restoring power.
