ABB RVC8-1/5A Power Factor Controller

Product Overview

The ABB RVC8‑1/5A is a high-performance industrial power factor controller designed to monitor and automatically adjust the power factor of electrical systems. By controlling capacitor banks, it reduces reactive power losses, minimizes network losses, and helps avoid electricity penalties. Suitable for three-phase 380–440 V systems, it is widely used in industrial, commercial, and large building applications for efficient power management.
