FAQs
This transformer is ideal for industrial facilities with nonlinear loads such as motor drives and power electronics. Its K-Factor nonlinear design mitigates harmonic heating, while the 400-208Y/120 V three‑phase configuration fits common panel boards. It pairs with standard distribution rooms and Eaton support tools to simplify procurement and field installation.
Key specs include a 50 KVA rating, three-phase configuration, and a 400-208Y/120 V secondary. It uses copper windings for high conductivity and has a 150°C rise rating, indicating resilience under heavy loads. These features collectively support reliable operation in harmonic-rich environments and enable efficient power delivery to controls and ancillary equipment.
Yes. The N39M28T50XCU employs a K-Factor nonlinear design specifically to manage harmonics produced by VFDs and similar nonlinear loads. This reduces overheating risks, improves voltage stability, and enhances overall system reliability in facilities with variable-frequency drives and other harmonic sources.
Certification status is project-specific. Contact Eaton to confirm applicable CE, SIL, and IP ratings for your region and installation. The product catalog and datasheets provide official certification details; availability may vary by country and application requirements.
The transformer’s copper windings and ventilated cooling reduce resistive losses and heat-related wear, contributing to lower energy usage and longer service intervals. In practice, this translates to reduced maintenance costs and fewer unplanned outages, delivering a favorable total cost of ownership in plants with high harmonic activity.
