The 400 kVAR total capacity with 8 x 50 kvar steps delivers precise, modular power factor correction, enabling measurable energy savings and reduced utility penalties in medium-to-large installations. This feature translates to lower reactive current and improved voltage regulation across the distribution network, supporting more stable motor and drive performance in manufacturing lines and processing facilities. The 481 A amperage rating at 480 V and 60 Hz ensures compatibility with standard low-voltage, three-phase infrastructure, allowing straightforward integration into existing switchgear without extensive rewiring. Heavy-duty capacitor cells paired with fuse protection boost reliability in harsh industrial environments, minimizing downtime and maintenance cycles while meeting safety standards. The compact footprint and defined dimensions (40 in L x 48 in W x 86 in H) with a 980 lb weight simplify retrofits and installation planning, especially in constrained service areas. Certifications CSA Certified UL Listed provide regulatory alignment and procurement confidence, while the warranty offers post-sale support and protection for capital investments. This solution is designed to work seamlessly with Eaton’s AutoVAR ecosystem, facilitating scalable PF correction as facility loads evolve, and it supports energy-management initiatives without sacrificing system safety or performance. Overall, PF correction with this capacitor bank delivers tangible improvements in efficiency, equipment longevity, and operational reliability for industrial facilities.

FAQs
Yes. The 400TPHSR431 is designed for 480 V, three-phase systems operating at 60 Hz and integrates with standard low-voltage switchgear. Its 40 x 48 x 86 inch footprint and 980 lb weight should be accounted for in rack and room planning, but its modular 8 x 50 kvar configuration simplifies retrofit without major panel modifications.
The unit provides 400 kVAR total, arranged as 8 modules of 50 kvar each. This modular setup enables stepwise PF correction to match load profiles, reduce reactive current, and minimize voltage drop under peak demand conditions. Operators can sequence capacitor steps to optimize energy savings across varying production cycles.
Industries with dense motor loads and dynamic process streams—such as manufacturing, metalworking, and data centers—benefit from improved power factor and voltage stability. The 480 V three-phase, 60 Hz design is ideal for mid-to-large facilities seeking energy-cost reductions, equipment life extension, and compliance with utility or regulatory PF requirements.
The 400TPHSR431 is CSA Certified and UL Listed, ensuring adherence to recognized safety and performance standards. These certifications support procurement decisions, installation approvals, and ongoing compliance with electrical codes in North American facilities.
ROI comes from reduced reactive power charges and improved motor efficiency, with maintenance focused on checking fuse protection and capacitor health. The unit’s heavy-duty cells are designed for reliability in demanding environments, and a one-year warranty (or 18 months from shipment) provides initial risk mitigation while service and support from Eaton add long-term value.
