Eaton N48M28F4921CUTRLS48 K-Factor nonlinear ventilated transformer - DOE2016 Efficient
Part Number: N48M28F4921HDI4
Quick Summary
K-Factor nonlinear ventilated transformer is a rugged power transformer for industrial and data center power distribution. Engineers face mounting pressure to meet DOE2016 efficiency targets while minimizing heat, footprint, and installation time. UL Listed and DOE2016 Efficient certifications underpin safety, performance, and energy compliance, while the three-phase 480 V primary with 208Y/120 V secondary covers common facility layouts. The 150 kVA rating supports peak demand without oversizing, and K13 features address harmonics and reliability in demanding environments. This solution translates into lower energy losses, reduced cooling requirements, and a shorter ROI cycle, making it well suited for retrofit projects and new builds in manufacturing, logistics, and process industries.

FAQs
Installation should align with the 480 V primary and 208Y/120 V secondary configuration, three-phase design, and the standard wiring connection 283B. The unit uses a 943 frame and weighs about 1200 lb, so ensure adequate floor loading, clearance for ventilation, and proper mounting to brackets or dedicated pad. Verify UL Listed compliance during panel integration and confirm electrical clearances per local codes.
Key specs include a 150 kVA rating, three-phase configuration, primary voltage of 480 V, secondary voltage 208Y/120 V, and a 115 °C rise. The transformer adheres to DOE2016 Efficient standards and carries UL Listed certification, supporting reliable energy performance and safety in demanding environments.
Yes. The unit is UL Listed, confirming compliance with safety and performance standards, and DOE2016 Efficient, indicating energy-efficient operation suitable for meeting modern regulatory targets and reducing operating costs in continuous duty applications.
It is well suited for industrial power distribution, data centers, manufacturing lines, and distribution panels that require reliable three-phase power with efficient, compact cooling. Its 150 kVA rating, 480 V to 208Y/120 V configuration, and K13 features make it a fit for retrofit projects and new builds seeking energy savings and improved thermal performance.
Expect lower energy losses due to DOE2016 efficiency, reduced cooling and fan load, and improved reliability from K13 harmonic considerations. These factors can shorten payback periods compared with older, less efficient models, while UL certification supports ongoing compliance in regulated environments.
