400 kVAR total capacity with 8 x 50 kVAR steps enables scalable reactive power support, letting engineers tailor correction to actual load conditions. This modular stepping lets you tune compensation to match real-load profiles, reducing energy charges, improving power factor, and avoiding penalties from utility tariffs. Designed for low-voltage, three-phase systems in manufacturing and process environments, it supports reliable operation without complexity. 600 V, 60 Hz rating ensures compatibility with standard LV distribution and switchgear, minimizing the need for adapters. This simplifies installation, shortens commissioning, and reduces retrofit risk when upgrading existing plants. Applications include motor drives, stamping lines, extrusion, and other high-demand loads where consistent power quality matters. Heavy-duty capacitor cells withstand industrial duty cycles, frequent switching, and temperature variations typical in factories. This robustness reduces maintenance intervals and unexpected outages, keeping production on track. The reference to 60 Hz operation ensures stable voltage across a broad load range. NEMA 3R enclosure and floor mounting provide versatile installation options for indoor switchgear rooms or sheltered outdoor locations. The protective enclosure enhances safety, moisture resistance, and service access, enabling quicker replacements and routine inspections. Use cases include retrofits and new builds where a floor-mounted VAR bank is preferred. Fused protection adds fault isolation and safer start-up sequences, protecting both the bank and downstream equipment. Quick-replace options and clear fault indicators reduce mean time to repair and simplify maintenance. The design supports reliable operation in demanding environments across manufacturing, processing, and infrastructure facilities. UL Listed and CSA Certified indicate safety and performance compliance, supporting reliability, traceability, and audits. These certifications simplify procurement, warranty handling, and maintenance reporting while meeting site standards. Within the AUTOVAR 600 ecosystem, the 400TPHSR631W delivers consistent power quality across LV networks.
