FAQs
Verify three-phase 480V service availability, confirm wall-mount suitability in your electrical room, and reference the 14 in depth, 36 in width, 60 in height footprint. Ensure mounting surface rating and enclosure clearances meet local codes and UL 508A/UL 810 requirements.
The unit operates at 480V three-phase with a 175 kvar rating, providing substantial reactive power compensation. This improves power factor, reduces utility penalties, and stabilizes voltage under varying load from motors and conveyors.
Yes. Its AutoVAR switching and 175 kvar rating make it a strong candidate for medium-to-large motor loads in manufacturing, helping to optimize energy usage, meet code requirements, and simplify future expansions in power factor correction.
It carries UL 508A, CSA Std. C22.2 No. 190, UL 810, and IEEE Std. 18. These certifications validate electrical safety, control-system compatibility, enclosure integrity, and electrical performance for industrial environments.
The AutoVAR approach reduces reactive power charges and improves efficiency, delivering cost savings over time. With a robust enclosure and standard components, maintenance requirements are typically limited to periodic inspection and connection checks as outlined in the Eaton specification sheet.
