High-capacity reactive power with a 500 kVAR rating and 480 A current capability delivers immediate power-factor correction and reduced line losses. This results in a steadier bus voltage, lower transformer loading, and the potential to defer expensive equipment upgrades. The unit supports three-phase, 600 V operation at 60 Hz, making it ideal for large motor-driven lines in manufacturing, metals processing, and material handling. Granular control is built into the 10 x 50 kVAR stepped approach, allowing precise VAR shaping without over-correcting. The stepped design minimizes transient overshoot and improves voltage stability during load swings, which translates to smoother motor starts and fewer nuisance trips. This capability is particularly valuable in environments with PWM drives, robot cells, or batch processing lines. Integrated main breaker and fuse protection simplify wiring and compliance, reducing panel space and installation time. With an included main protection option, customers benefit from safer commissioning and easier preventive maintenance. This construction supports quick upgrades and serviceability in floor-mounted configurations found in busy plant rooms. Rugged NEMA 3R enclosure, floor mounting, and L-sized chassis provide robust protection against dust, moisture, and incidental impact in typical industrial settings. The enclosure and mounting choices are designed for long life in demanding environments. The NEMA 3R, floor-mounted, L-sized design resists weather, dust, and vibration, helping to maintain performance with minimal downtime. Compatibility and scalability with the AUTOVAR 600 family enable phased deployments and future capacity expansion without replacing existing infrastructure. This approach supports retrofit projects and new builds with phased investment. Quality and support are ensured by UL Listed and CSA Certified compliance, plus the standard Eaton warranty and service ecosystem that minimize maintenance downtime and preserve asset value.

FAQs
Mount the unit on a suitable floor location and connect the three-phase 600 V supply to the integrated main breaker following local electrical codes. Tie into the AUTOVAR 600 network with proper feeders and ensure fused protection remains in place. Design the wiring path to minimize impedance and maintain accessibility for routine maintenance and inspections.
Verify 480 A amperage rating and 500 kVAR reactive power at 600 V with 60 Hz operation. Confirm three-phase configuration and the 10 x 50 kVAR stepped control for granular VAR shaping. Ensure enclosure is floor-mounted with a NEMA 3R rating and that the unit includes an integrated main breaker for streamlined switching and protection.
Yes, it is well-suited for low-voltage power factor correction in facilities with large motor loads, drives, and critical cooling or processing equipment common in data centers and manufacturing. The floor-mount, NEMA 3R enclosure and integrated protection support reliable operation in busy indoor spaces while delivering measurable energy savings and voltage stability.
The unit is UL Listed and CSA Certified, providing third-party confirmation of safety and compliance to industry standards. These certifications help satisfy regulatory audits, support safer installation practices, and facilitate acceptance in multi-site projects with stringent quality requirements.
The product carries a one-year warranty from installation or an 18-month warranty from shipment, whichever occurs first. ROI is driven by improved power factor, reduced demand charges, and lower transformer loading, yielding energy savings, extended equipment life, and faster payback on both retrofit and new-build projects.
