Eaton V48M28T45CUNV Transformer - UL Listed, Totally Enclosed Non-Ventilated
Part Number: V48M28T45CUNV
Quick Summary
The Eaton V48M28T45CUNV transformer provides dry-type distribution from 480 V to 208Y/120 V for panel applications. In many plants, heat buildup, maintenance downtime, and voltage fluctuations hinder reliability and uptime. UL Listed certification accompanies a 150°C rise rating and a totally enclosed non-ventilated (TENV) enclosure, delivering safer operation in dusty, demanding environments. With copper windings, a robust DT-3 design, and a 45 kVA rating, this transformer supports efficient, scalable energy distribution for industrial controls. Its compact frame and flexible taps help optimize performance while reducing total cost of ownership in power distribution schemes. Designed for three-phase systems and standard control panel installations, it simplifies sourcing and stocking for maintenance teams.
