The 300 kVA rating paired with a 400 V primary and 208Y/120 V secondary provides scalable power conversion for plant-level distribution, reducing the need for multiple step-down units and streamlining installation. The DOE 2016 Efficient standard translates to lower no-load and load losses, delivering measurable energy savings over the life of the installation while helping you meet sustainability goals. Aluminum coil windings offer corrosion resistance and cost efficiency, contributing to a lighter, durable transformer with solid heat dissipation for steady operation in demanding environments. The NEMA 2 enclosure and floor-mount design simplify site integration and protection against dust and moisture, while the 60 Hz rating ensures compatibility with common utility and facility power networks. Tap adjustments (+2 at 2.5% FCAN, -4 at 2.5% FCBN) enable volt- relationship fine-tuning to maintain voltage regulation under varying loads, reducing equipment stress and extending service life. With UL Listed certification, 10 CFR Part 431 compliance, and a sound level aligned to NEMA ST-20, this unit supports compliance-driven installations and predictable maintenance planning. Real-world installations benefit from the Weathershield RH6 option for outdoor or harsh environments, and the robust floor-mount footprint aligns with typical plant layouts, minimizing retrofits. In short, N39M28T3316 delivers efficiency, reliability, and ease of installation for industrial power distribution and motor-starting applications.
