An Automatic Capacitor Panel, also known as an Automatic Power Factor Correction (APFC) panel, is an electrical enclosure designed to improve a facility's power factor. Manufacturers of these panels build systems that automatically switch capacitor banks on or off in response to fluctuating electrical loads. This reduces reactive power consumption, which leads to lower electricity bills, avoids penalties from utility companies, and enhances the overall efficiency and stability of the electrical network. Major manufacturers include Schneider Electric, ABB, and BCH.
