The three-phase, floor-mounted AutoVAR design provides automatic reactive power compensation for 480V systems, delivering a measurable reduction in kVAR penalties and improved power factor. This translates to lower energy costs and extended motor and equipment life due to reduced voltage stress and overheating. The unit’s 350 kvar capacity ensures robust performance across variable loads, while its 26 in depth, 38.5 in width, and 78 in height enable practical integration into established plant layouts. Compatibility with standard Eaton or compatible switchgear simplifies installation and future upgrades, with UL 508A, CSA, UL 810, and IEEE 18 certifications providing assurance of safety and compliance. Common objections about maintenance are addressed by proven reliability and modular replacement approaches, reducing downtime and overall cost of ownership. This solution is particularly well-suited for manufacturing lines, process facilities, and data centers seeking consistent power quality and measurable ROI.

FAQs
Installation requires floor mounting in a suitable enclosure or dedicated equipment room with adequate clearance for ventilation and access. Ensure proper wiring to protective devices, adherence to UL 508A and IEEE 18 guidelines, and compatible connection to existing switchgear. Verify three-phase 480V supply, correct phase rotation, and secure mounting hardware to withstand facility vibrations.
The 350 kvar rating provides substantial reactive power correction across typical industrial loads, improving power factor and reducing voltage drop during peak demand. AutoVAR switching optimizes capacitor engagement to match real-time load, delivering energy savings, lower utility penalties, and smoother motor operation without overcompensation that could destabilize the system.
The unit is certified to UL 508A for industrial control equipment, CSA Std. C22.2 No. 190 for Canadian compliance, UL 810 for electrical equipment in specialized environments, and IEEE Std. 18 for capacitor banks. These certifications support safe installation, reliable performance, and regulatory alignment across North American facilities.
ROI comes from reduced reactive power charges, improved motor efficiency, and delayed capacitor replacement costs due to robust design. Expect measurable energy savings as power factor improves, along with lower maintenance downtime because of Eaton’s modular, service-friendly architecture. A site-specific analysis should factor load profile, energy tariffs, and existing harmonics for precise payback timing.
Industries with heavy motors and variable loads—such as plastics, metal fabrication, food and beverage processing, water treatment, and data centers—benefit most. Applications include plant-wide power factor correction, motor drive efficiency optimization, and improved voltage regulation at 480V. The unit supports scalable deployment in retrofit projects or new builds with robust safety certifications.
