550 kVAR rating with 11 x 60 kVAR steps provides granular reactive power control, enabling precise matching to dynamic load profiles seen in modern plants. The business impact is clearer voltage profiles, reduced utility penalties, and faster return on investment when peak demand shifts occur. 529 A amperage at a 600 V rating supports heavy industrial demand without oversizing, delivering reliable correction during peak motor loads and conveyors. This capability minimizes voltage drop on feeders, protects sensitive equipment from sag, and improves process stability. Floor-mounted, NEMA 1 enclosure simplifies installation in crowded plant spaces and facilitates safe service access for maintenance crews. The design also supports easy retrofit into existing switchgear rooms and aligns with common facility standards for indoor electrical equipment. Fused protection enhances safety and fault containment, extending capacitor life and reducing unplanned outages. This feature also streamlines compliance testing and maintenance procedures, helping reliability teams document protective coordination. Heavy-duty capacitor cells are built for long life in harsh environments, maintaining performance with reduced maintenance cycles. Users benefit from consistent PF correction over time, minimizing calibration work and service disruption. Designed to operate seamlessly with the AUTOVAR 600 line, it enables modular, scalable PF correction across multiple feeders and plants. The integration helps facility managers standardize power management practices and simplify spare parts planning. UL Listed and CSA Certified status supports regulatory acceptance across North American facilities, while 60 Hz operation and 600 V rating align with common utility requirements.
