FAQs
Begin with confirming the available space given the 35.57 in length, 51 in height, and 34.5 in width. Use proper lifting gear due to the 1093 lb weight, ensure mounting surfaces are level, and provide adequate ventilation. Connect the three-phase input/output to compatible bus and switchgear rated for 45 kVA at 480D-480D. Verify UL Listed compliance during installation and follow Eaton’s datasheet for clearances, labeling, and grounding guidelines.
Yes. The unit is specified as three-phase with a 480D-480D configuration and a 45 kVA rating, which aligns with standard 480V distribution in industrial facilities. Ensure that switchgear and downstream equipment are sized to handle the 45 kVA load, and consult the Eaton specification sheet for wiring diagrams and terminal details to confirm compatibility with your bus bar system.
The transformer incorporates a K-Factor nonlinear design (K13 vented XFMR) that mitigates thermal stress from harmonics produced by nonlinear loads such as drives and power electronics. This improves thermal stability, reduces overheating risk, and helps maintain voltage regulation under harmonic conditions. In practice, this translates to higher reliability for motors, drives, and IT equipment in manufacturing and data-center environments.
The product carries UL Listed certification, confirming compliance with recognized safety standards for electrical equipment in many markets. The provided data does not specify CE or IP ratings; for region-specific installation requirements, consult Eaton’s datasheet or regional compliance guidance to ensure alignment with local regulations and facility codes.
The combination of UL Listed safety, a ventilated K-Factor design, and a 45 kVA three-phase rating delivers robust reliability under nonlinear loads while managing heat more effectively. Benefits include reduced unscheduled downtime, extended transformer life, and lower energy-related losses in harmonically loaded systems, contributing to a favorable total cost of ownership over the equipment lifecycle.
