The 300 kVAR switched capacitor bank delivers staged correction with 6 x 50 kVAR steps, enabling precise power factor management and current control. This staged approach reduces inrush and fatigue on feeders while optimizing capacitor loading, resulting in lower energy losses and improved voltage regulation across the plant. It is ideal for 600 V, 60 Hz industrial feeders in low-voltage distribution networks, supporting consistent performance as demand fluctuates. Heavy-duty capacitor cells paired with a floor-mounted, NEMA 3R enclosure provide rugged reliability in both indoor and outdoor environments, simplifying installation and service during maintenance windows. Fused protection isolates faults quickly, improving overall system safety and uptime in manufacturing lines and process facilities. The compact, modular design supports easy expansion to 300 kVAR total capacity while maintaining compatibility with existing AUTOVAR 600 systems and control schemes. UL Listed and CSA Certified components help ensure compliance with critical safety standards, reducing procurement risk and accelerating project approvals. This capacitor bank aligns with typical industry practices for power factor correction in low-voltage applications, delivering measurable efficiency gains and lower operating costs over the equipment lifecycle.
