Eaton N48M47F75CUEELS45 K-Factor Transformer - UL Listed
Part Number: N48M47F75CUEELS45
Quick Summary
Eaton N48M47F75CUEELS45 is a K-Factor nonlinear ventilated transformer for three-phase distribution in industrial facilities. Many engineers contend with harmonic distortion, unexpected heat, and noisy operation that compromise uptime and efficiency. This transformer is designed to address those pain points with KT-13 nonlinearity, taps at +2.5% and -2.5%, and a 75 kVA rating that supports critical loads without overstress. UL Listed and NEMA TP-1 compliant, it also features low sound performance at 45 dB and electrostatic shielding for improved reliability in electrified environments. By combining robust construction with proven efficiency and weather protection, Eaton helps reduce lifecycle costs, simplify compliance audits, and enable more predictable power delivery for critical equipment and infrastructure.
