Eaton N48M28T5216 Nonlinear Ventilated Transformer-DOE2016
Part Number: N48M28T5216
Quick Summary
Introducing the Eaton N48M28T5216 nonlinear ventilated transformer, designed for robust power distribution in industrial facilities. This unit helps maintain voltage stability under fluctuating loads while meeting stringent DOE 2016 efficiency standards. With UL Listed certification and DOE 2016 Efficient compliance, it also features a rugged NEMA 2 enclosure for durable service in harsh environments. Aluminum windings, a K-Factor of 13, and a 250 kVA rating support reliable three-phase operation from 480 V primary to 208Y/120 V secondary across data centers, manufacturing lines, and process plants. Floor- or wall-mount compatibility, generous dimensions, and a WS62 weather shield further enhance installation flexibility and long-term reliability.

Selling Policy 25-000 - Distribution and Control Products and Services
Energy efficiency and regulatory compliance drive lower operating costs. DOE 2016 efficiency and UL Listed certification translate into tangible business value by reducing energy waste and easing audits across facilities. The K-Factor 13 nonlinear rating improves power quality in harmonic-rich environments, such as systems with VFDs and UPS feeds, delivering steadier voltage and reduced overheating risk for longer transformer life. The 480 V primary delta to 208Y/120 V secondary setup supports critical loads and scalable plant distribution, enabling reliable service without premature equipment replacement. Tap options of 2 at +2.5% and 4 at -2.5% allow precise voltage regulation to minimize secondary drift in varying supply conditions. Rugged construction — NEMA 2 enclosure, FR945 frame, 220 °C insulation, and 150 °C rise — ensures durability in harsh environments, with WS62 shielding for outdoor or semi-exposed installations. Floor or wall mounting, 283B wiring, and a 250 kVA class footprint support fast, compliant installation and serviceability.
