FAQs
Plan for wall-mounted installation in a clean, accessible area near the distribution panel. Ensure adequate clearance for venting and service access, and verify compatibility with your Eaton or compatible switchgear. Check that 240V three-phase supply is stable and that the panel supports kvar-level upgrades.
General: three-phase AutoVAR, 240V, 100 kvar rating, wall-mounted enclosure; dimensions ~14 in depth with a 36 in x 36 in face, weight ~280 lb. Certifications include UL 508A, UL 810, CSA, and IEEE 18. Includes UPC 786685198262.
Yes. The 100 kvar three-phase bank provides reactive power correction to stabilize voltage, reduce current, and improve efficiency in motor-driven plants and data centers with high diversified loads and cooling systems.
It carries UL 508A and UL 810 certifications, CSA standard compliance, and IEEE 18. These certifications ensure electrical safety, reliability, and compatibility with industrial controls and protective equipment, reducing risk for panel builders and end users.
Expected ROI comes from lower utility costs due to improved power factor and reduced line losses, plus fewer maintenance events due to a rugged, purpose-built design. Plan for periodic inspections, verify mechanical connections, and monitor runtime to optimize remaining kvar capacity and ensure continued performance.
