Eaton N48M28B3016CU K-Factor Transformer - DOE 2016 Efficient
Part Number: N48M28B3016CU
Quick Summary
Eaton K-Factor nonlinear ventilated transformer provides efficient power isolation for three-phase distribution in industrial environments. Facilities often battle energy waste, heat buildup, and voltage variability when transformers are not matched to load or ambient conditions. This model carries UL Listed safety certification, meets DOE 2016 efficiency requirements under 10 CFR Part 431, and utilizes a rugged NEMA 2 enclosure for reliability in harsh spaces. With copper windings, the FR940 frame, and an 80 °C rise rating, it delivers consistent performance under load while helping maintain cooler operation and longer component life. Designed for floor or wall mounting in machine rooms, panel substations, and distribution cabinets, the N48M28B3016CU steps from 480 V to 208Y/120 V in a compact footprint.

FAQs
The transformer provides a 480 V primary input and a 208Y/120 V three-phase secondary, suitable for stepping down higher plant voltage to standard control and instrumentation levels in three-phase systems operating at 60 Hz.
Yes. The unit is UL Listed and complies with DOE 2016 efficiency requirements under 10 CFR Part 431, delivering energy-conscious performance while meeting safety and regulatory standards for industrial power distribution.
Plan for floor or wall mounting within a NEMA 2 enclosure, allocate space for ventilation, and account for approximately 507 lb weight. Termination uses 283B wiring connections, with a FR940 frame that fits standard industrial layouts and allows straightforward electrical labor.
Ideal for three-phase power distribution in machine rooms, distribution panels, and control cabinets where 480 V to 208Y/120 V conversion is needed, especially in environments with non-linear loads and a need for reliable voltage regulation.
A K-Factor of 13 indicates good mitigation of harmonic distortion from nonlinear loads, improving efficiency and reducing stray heating. This makes it well-suited for motor drives and other equipment with non-sinusoidal current profiles, contributing to longer transformer life and steadier downstream voltage.
