Three-phase 480 V operation at 60 Hz with a 601 A rating enables direct integration with common industrial feeders, delivering precise power factor correction and reducing reactive power demand. This translates into lower utility penalties and more stable voltage across sensitive equipment, improving uptime for critical processes. The 500 kVAR total capacity, distributed as 10 × 50 kVAR steps, provides granular tuning of reactive power to match load profiles, supporting efficiency gains in manufacturing lines and data centers while avoiding large inrush during switching events. Heavy-duty capacitor cells paired with a robust NEMA 3R enclosure enhance durability and service life in harsh environments, reducing maintenance frequency and lifecycle costs. A built-in main breaker and fuses offer safe fault isolation and straightforward service, simplifying retrofits and upgrades within existing switchgear. The enclosure design supports outdoor placement and weather resilience, enabling flexible installation in plant yards or equipment rooms. Certifications including UL Listed, CSA Certified, UL 508A, and IEEE 18 compliance reassure compliance with industry codes and supplier qualification requirements, streamlining procurement and qualification for regulated facilities. Overall, the AutoVAR 600 solution aligns with energy-management programs, helping facilities meet efficiency targets, reduce energy spend, and improve grid stability without sacrificing reliability.

FAQs
Plan for adequate clearance and a solid base, mount the enclosure in a compliant location, connect to three-phase 480 V supply, and wire to the main breaker and fuses per Eaton installation guidelines. Verify NEMA 3R suitability for your site, follow UL 508A wiring practices, and ensure protective relays and fault isolation are functional. Schedule commissioning with a qualified electrician to validate PF correction settings and load steps.
The unit operates three-phase at 480 V, 60 Hz, with a 601 A amperage rating and a total kVAR of 500, implemented as 10 × 50 kVAR steps. It includes a main breaker and fuses for protection, and uses a heavy-duty capacitor string in a NEMA 3R enclosure. It is UL Listed, CSA Certified, and compliant with UL 508A and IEEE 18 standards, ensuring safe, code-aligned installation.
Yes. The 500 kVAR PF correction capability reduces reactive power, improves voltage profiles, and lowers utility penalties. Its modular 10 × 50 kVAR stepping allows precise tuning to load changes typical in manufacturing lines, while the rugged enclosure and certified safety features simplify integration with existing plant power systems and energy-management initiatives.
The unit is UL Listed and CSA Certified, with UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 compliance. These certifications confirm electrical safety, control-panel compatibility, and performance standards, supporting procurement approvals and regulatory adherence for regulated facilities.
Eaton offers a one-year warranty from installation or eighteen months from shipment, whichever occurs first, under policy 25-000. For ongoing reliability, plan routine inspections of capacitor cells, enclosures, and protective devices, and maintain an inventory of critical spares to minimize downtime during scheduled maintenance or fault events.
