Eaton N48D28B5516QCU GP Ventilated Transformer - DOE2016

DOE2016 Efficient design reduces core losses and idle heat, delivering tangible energy savings across continuous-duty applications. In practice, this means lower utility bills and cooler switchgear rooms for 500 kVA transformers when serving 480 V primary systems and 208Y/120 V secondary loads. The Eaton N48D28B5516QCU aligns with DOE 2016 expectations while maintaining interconnectivity with standard low-voltage distribution panels. Copper windings provide high conductivity and long-term reliability, improving thermal stability at an 80 °C rise. This translates to fewer thermal excursions in crowded control cabinets and longer service life under typical industrial duty cycles. Combined with a robust insulation system rated at 220 °C, you gain predictable performance in varying ambient conditions. NEMA 1 enclosure and GP frame deliver simple installation and compatibility with existing floor-mounted footprints. The spacious footprint accommodates venting and service access, reducing commissioning time and facilitating routine maintenance. For retrofit projects, the taps (+2 at 2.5% FCAN, -2 at 2.5% FCBN) offer voltage regulation without extra components. Tap size accessibility supports voltage regulation across load variations, which minimizes downstream equipment stress and improves regulator performance. In data centers or manufacturing lines with tight tolerances, the built-in taps help keep secondary voltage within spec, reducing equipment nuisance tripping and optimizing protective relays. UL Listed certification and DOE2016 efficiency together mitigate procurement risk, supporting compliance and supplier confidence in regulated environments. The K-13 modification signals a design tuned for modern efficiency standards, simplifying auditing and spare-part planning for maintenance teams.
