20 uF Motor Run Capacitor for Air Conditioners and Electric Motors

Reliable Motor Run Capacitor Replacement

This 20 uF motor run capacitor is designed to provide stable, continuous operation for single-phase AC motors. Rated for 370 VAC or 440 VAC operation, it is a direct replacement for most round motor run capacitors used in air conditioners, heat pumps, and general motor applications. With a tight ±5% capacitance tolerance, it helps maintain proper motor performance, efficiency, and reliability.

UL Certified Safety and Durable Construction

Built to meet demanding electrical standards, this motor run capacitor is UL and CUL certified and compliant with CEL and TÜV SÜD requirements. The CBB65-style aluminum housing is engineered for long service life and includes a 10,000 AFC anti-explosion pressure interrupter for added safety. It is designed to operate reliably in temperatures ranging from -13°F to 158°F (-25°C to 70°C).

Wide Compatibility for HVAC and Motor Applications

This capacitor is commonly used in air conditioner condensers, heat pumps, pool pumps, washing machines, air compressors, and other single-phase electric motors. It replaces any run capacitor rated at 440V AC or lower, with a 20 microfarad value. Standard 0.250 inch quick-connect terminals allow for easy installation without wiring or adapter changes.

Simple Installation with Clearly Labeled Terminals

The top terminals are clearly marked for straightforward installation. Terminals labeled “HERM” or “H” connect to the compressor motor, “FAN” or “F” connect to the fan motor, and “C” connects to the common line. This makes it easy to install correctly and safely in compatible systems.
