Eaton N48M28T1221CUSRTR Transformer - K13 K-Factor, DOE2016 Efficient
Part Number: N48M28T1221CUSRTR
Quick Summary
Eaton N48M28T1221CUSRTR transformer is a high-efficiency three-phase device designed for demanding industrial power distribution. In facilities with non-linear loads, outdated transformers waste energy and overheat cooling systems, increasing maintenance costs. This model meets DOE2016 Efficient standards, is UL Listed, and carries a K13 K-Factor rating for better tolerance to harmonic currents. Its ventilated design, solid frame, and precise voltage regulation deliver lower operating costs, safer temperatures, and extended service life for data centers, manufacturing lines, and critical facilities. By pairing efficiency with reliable secondary voltage of 208Y/120 V from a 480 V primary, it supports scalable distribution without compromising performance.

FAQs
Plan floor mounting with a footprint of 34.5 in by 51 in and ensure at least 31.5 in depth for service clearance. The unit weighs 1200 lb, so include adequate lifting points and anchoring. Connects via 283B wiring, supports three-phase 480 V primary and 208Y/120 V secondary, and complies with UL Listed and DOE2016 Efficient standards for a compliant data-center or plant deployment.
It features DOE2016 Efficient performance and K13 K-Factor for non-linear loads, which reduces harmonic losses and heat. UL Listed certification ensures safety and reliability in industrial environments. Together, these aspects lower total cost of ownership by reducing cooling requirements and improving long-term reliability.
Yes. The transformer is designed with a 480 V primary and a 208Y/120 V secondary, delivering stable voltages for distribution to downstream equipment while maintaining performance with harmonic-rich loads thanks to K13 K-Factor.
This model is UL Listed and DOE2016 Efficient, with K13 K-Factor characteristics. UL Listing verifies safety and reliability in industrial installations, DOE2016 confirms energy efficiency, and K13 validates resilience to nonlinear load harmonics—crucial for hospitals, data centers, and manufacturing lines with strict compliance needs.
The combination of DOE2016 efficiency and reduced cooling load typically lowers energy costs and facility HVAC demand. The ventilated design and robust K-Factor improve cooling reliability, potentially extending service life. Regular inspection of wiring connections and protective devices, along with periodic thermal assessments, helps sustain performance and return on investment.
