Eaton N48D28T75CUEE Transformer - K-Factor Nonlinear Ventilated
Part Number: N48D28T75CUEE
Quick Summary
K-Factor nonlinear ventilated transformer provides clean, regulated power for critical control panels in industrial facilities. The Eaton N48D28T75CUEE delivers 75 kVA with copper windings in a three-phase KT-13 design, suitable for 480 V primary and 208Y/120 V secondary. Engineers often struggle with voltage fluctuations, heat buildup, and downtime in demanding environments; this model offers ±2.5% taps (two up and two down) for voltage regulation and a robust cooling profile to mitigate heat. Certification documentation is available on request from Eaton to support project approvals. With copper windings and a rugged ventilated construction, it enables reliable power distribution in control panels and motor control centers, reducing risk and enhancing uptime across industrial applications.
