The 550 kVAR switched capacitor bank delivers precise reactive power management, enabling meaningful improvements in power factor and reduced utility charges. This translates to lower energy costs and better system efficiency, especially for facilities with heavy motor loads such as conveyors and pumps. The 11 x 50 kVAR stepping provides granular control to match varying load conditions, improving voltage stability across the plant during peak demand. With a 600 V, 60 Hz, three-phase configuration, the unit integrates smoothly with standard industrial power systems, minimizing integration risk and facilitating quick commissioning. Heavy-duty capacitor cells are housed in a floor-mounted, NEMA 3R enclosure, ensuring long-term reliability in dusty or humid environments and simplifying maintenance access. The integrated main breaker option and fused protection deliver safer startup and service, reducing downtime during preventative maintenance or fault conditions. The footprint and weight are compatible with well-planned floor space in new builds or retrofit installations, while the AUTOVAR 600 compatibility supports scalable expansion as demand grows. Overall, the design prioritizes ease of installation, compliance, and predictable ROI through improved power quality and energy efficiency.
