Eaton N48M28F75EETR Nonlinear Transformer UL Listed
Part Number: N48M28F75EETR
Quick Summary
The Eaton N48M28F75EETR nonlinear transformer provides clean, reliable power conditioning for industrial and commercial electrical systems. Voltage swings and harmonic distortion can stress sensitive equipment and trigger unplanned downtime; this unit helps stabilize supply and protect downstream controls. UL Listed, a NEMA 2 enclosure, and a certified test report per CMI style demonstrate compliance and rugged field performance. Designed for 75 kVA, three-phase operation with 480 V primary and 208Y/120 V secondary, it also offers taps at +2.5% and -2.5% for precise voltage tuning. By integrating advanced K-Factor nonlinear behavior with electrostatic shielding, it supports efficient power distribution while reducing maintenance costs in harsh plant environments. This makes it a solid choice for industrial power distribution and electrical infrastructure projects.
