Quick Summary

Eaton LV AutoVAR 600 capacitor bank improves power factor for three-phase industrial systems. Too often operators face energy waste, tariff penalties, and voltage swings when PF is neglected. Key certifications include UL Listed, CSA Certified, UL 508A, and IEEE Std. 18, ensuring safe, compliant operation in demanding facilities. Designed for 480V systems, the AutoVAR 600 avoids costly misconfigurations with a robust main breaker and fuses and heavy-duty capacitor cells. Implementing this solution translates to reduced energy costs, steadier voltage profiles, and improved reliability across manufacturing lines and automation projects. The unit supports scalable PF correction with 8 x 50 kvar steps, enabling precise tuning to your site load profile.

FAQs

The unit requires a three-phase 480V supply at 60 Hz and adequate space in the electrical room to accommodate dimensions of 25 inches depth, 41.3 inches width, and 80 inches height. With a weight around 1000 pounds, plan for proper lifting gear and ventilation. It connects to the main switchgear via a dedicated feeder and includes a main breaker and fuses for safe, code-compliant integration.
Key specs include a 400 kVAR total rating achieved through 8 x 50 kvar steps, 481A amperage rating, 60 Hz frequency, and 480 V three-phase voltage. This configuration delivers precise reactive-power management, enabling rapid PF improvements and better control of demand charges for industrial motors and drives.
Yes. The unit is UL Listed and CSA Certified, with additional compliance to UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18. These certifications support safe operation, electrical-code compliance, and reliability in regulated industrial environments.
Warranty terms specify one year from installation or eighteen months from shipment, whichever occurs first, per Eaton Selling Policy 25-000. Post-sale support includes access to Eaton datasheets and specification sheets, with options for service coordination, spare parts, and installation guidance to maintain optimum PF performance.
By delivering up to 400 kvar of PF correction, the unit reduces reactive power, lowers energy costs, and minimizes demand charges. It also stabilizes voltage during motor starts and drives operation, improving equipment life and process uptime. The 480 V three-phase configuration supports scalable upgrades within existing automation and power-distribution infrastructure.
