FAQs
Yes. The unit is designed for 480V three-phase operation at 60 Hz, featuring a 421 A rating and a 350 kVAR capacity. It integrates with standard industrial distribution gear and includes a main breaker, enabling straightforward installation within typical plant power systems while meeting common electrical codes.
Key specs include a 350 kVAR total rating, 7 × 50 kvar stepping, 421 A amperage, 480 V voltage rating, and 60 Hz frequency. It is a three-phase PF correction solution with a NEMA 3R enclosure and a main breaker for protection, making it suitable for both indoor and outdoor industrial deployments.
The Eaton LV AutoVAR 600 is commonly used in manufacturing facilities, data centers, large commercial buildings, and HVAC-heavy processes. It provides precise reactive power control to improve power factor, reduce energy penalties, stabilize voltage, and protect sensitive equipment in environments with fluctuating motor loads and large drive systems.
The unit carries UL Listed, CSA Certified, UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18 compliance. These certifications support safe operation, code compliance, and widespread acceptance in regulated facilities, simplifying procurement and field installation.
Maintenance naturally centers on periodic inspection of capacitor banks and protective devices, with the main breaker serving as a critical protection point. Typical ROI comes from reduced reactive power charges and improved equipment efficiency across motor-driven loads, enabling faster payback in facilities with sizable PF penalties and high motor loads.
