Eaton 250TPHSR431MW LV AutoVAR 600 Switched Capacitor Bank - UL Listed
Part Number: 250TPHSR431MW
Quick Summary
Eaton LV AutoVAR 600 capacitor bank is a robust solution for low-voltage power factor correction in three-phase industrial networks. Many plants struggle with energy waste and voltage dips when outdated capacitor banks fail to keep PF in spec. UL Listed and CSA Certified construction paired with a rugged NEMA 3R enclosure addresses safety, reliability, and regulatory needs. This approach supports rapid commissioning, predictable maintenance, and measurable savings for facilities seeking efficient, compliant power factor correction. As part of a scalable solution, the 5 x 50 kVAR stepping with a 300 A rating lets engineers match reactive support to load changes without oversizing. In facilities that demand uptime and compliance, this capacitor bank aligns with third-party standards while enabling straightforward installation and future expandability.

The 250 kVAR rating with a 300 A amperage and 5 x 50 kVAR stepping lets you shape reactive power precisely as load changes, reducing utility demand charges and improving voltage stability in three-phase 480 V systems. This translates to tangible energy savings and more reliable equipment operation on the plant floor. Integrated main breaker enables quick isolation during maintenance, simplifying commissioning and reducing downtime while minimizing external wiring and potential fault paths. The rugged floor-mounted NEMA 3R enclosure supports indoor and outdoor placements, improving site flexibility and protecting capacitor cells in harsh environments. Fuses provide targeted protection for individual capacitor cells, enhancing reliability and extending service life in demanding industrial settings. UL Listed and CSA Certified compliance further reduces risk when deploying in regulated facilities, supporting enterprise-wide standards and supplier qualification.

FAQs
Begin by verifying 480 V, 60 Hz supply and confirming three-phase connections. Mount the unit on a solid floor, maintain adequate clearance, and connect to the AUTOVAR 600 control network. Use the integrated main breaker for safe isolation during maintenance and follow UL Listed/CSA Certified guidance during commissioning. Ensure proper fuse protection for capacitor cells and position the enclosure in a compliant indoor/outdoor location per NEMA 3R requirements.
The bank provides 250 kVAR total with 5 x 50 kVAR steps, enabling fine-grained reactive-power support as load varies. This stepping minimizes both overshoot and undershoot in PF correction, reducing peak demand charges and improving voltage stability. By matching steps to load profiles, engineers can achieve smoother transitions during start-up or demand spikes and avoid unnecessary capacitor cycling.
Yes. The 480 V three-phase rating, 60 Hz operation, and 250 kVAR capacity are well-suited for data centers, manufacturing lines, and similar facilities needing reliable PF correction. The floor-mounted, NEMA 3R enclosure supports challenging environments, while the integrated main breaker simplifies control and maintenance. UL Listed and CSA Certified design adds regulatory confidence for critical load scenarios.
This product is UL Listed and CSA Certified, providing recognized electrical-safety and performance assurances. These certifications help meet corporate and regulatory requirements across many industries, reduce the need for extensive third-party testing, and facilitate supplier qualification. The rugged NEMA 3R enclosure further supports compliance by protecting components against dust, moisture, and incidental exposure.
Expected maintenance focuses on periodic inspection of fuses and capacitor cells, with the integrated main breaker streamlining disconnection for service. ROI comes from lower energy consumption and reduced peak-demand charges due to improved PF, along with reduced downtime thanks to safer, simpler commissioning and robust enclosure protection. The unit’s ratings and certifications support long-term reliability in regulated environments.
