Product Overview
This 75kVA three phase VPI dry type transformer is designed for commercial facilities, light industrial power distribution, marine duty electrical rooms, and protected indoor or outdoor installation points requiring 208V to 208Y/120V power conversion.
Built with a NEMA 4X stainless steel enclosure, Class R insulation, copper windings, and a Dyn1 vector group, this transformer supports stable low voltage distribution while helping buyers match North American project requirements for enclosure protection, thermal performance, and specification review.
With 208V Delta primary input and 208Y/120V Wye-N secondary output, the unit is suitable for applications requiring both 208V three phase loads and 120V line-to-neutral branch circuits. The DOE 2016, ANSI, IEEE, and NEMA ST-20 aligned design makes it a practical choice for commercial, marine duty, and light industrial transformer projects.
