Eaton Specification Sheet - N48M47T49CUEE
The K-Factor nonlinear ventilated design is engineered to tolerate nonlinear harmonic loads, delivering improved transformer reliability and reduced thermal stress, which translates to fewer unplanned outages in continuous production. This directly supports uptime and energy cost control in high-demand environments. The 150 kVA three-phase configuration with a 480 V primary and 480Y/277 V secondary enables flexible distribution without multiple step-downs, limiting inventory while simplifying panel design and installation. Copper windings deliver higher efficiency and lower I2R losses, yielding measurable energy savings and cooler operation under load. Tap settings of +2.5% and -2.5% allow precise voltage regulation to protect sensitive equipment and maintain tolerance at varying line conditions. The unit’s electrostatic shielding and WS34 weather protection broaden its application window to outdoor or harsh indoor environments, reducing enclosure needs and maintenance. UL Listed and NEMA TP-1 compliant, along with the 150 °C rise insulation and 200 °C insulation system, provide a rigorous compliance and performance baseline, supporting compliance-driven procurement and long-term reliability. A robust 917 frame with copper windings and a 1600 lb build ensures mechanical stability during installation, while the 150 kVA rating aligns with typical industrial feeder designs and short-term overload scenarios, improving system resilience without overdesign. These features collectively enable faster commissioning, predictable maintenance planning, and lower total cost of ownership in manufacturing, distribution, and processing facilities.

FAQs
For 480V input, plan three-phase wiring with proper color-coded terminations, ensure ample clearance for ventilation, and confirm mounting on a rigid, level surface compatible with a 917 frame. Use the +2.5%/ -2.5% taps to fine-tune output under load and maintain voltage within tolerance. Follow manufacturer torque specs and local electrical codes for safe, compliant installation.
Key specs include a 150 kVA rating, three-phase configuration, primary voltage 480 V, secondary voltage 480Y/277 V, 60 Hz frequency, copper windings, and temperature rise of 150 °C. Tap settings are 2 at +2.5% and 4 at -2.5%, with an insulation system rated to 200 °C. Meets NEMA TP-1 and UL Listed requirements.
Yes. The unit is equipped with Electrostatic Shielding and Weathershield WS34 for outdoor and harsh indoor environments. This reduces enclosure needs and simplifies installation outdoors, while maintaining electrical performance. Ensure proper ventilation and clearance per NEMA guidelines, and use weather-rated connections to maximize reliability in non-lab environments.
