Eaton N48M28T75SRTRS64X-US Transformer - 75 kVA, UL Listed
Part Number: N48M28T75SRTRS64X-US
Quick Summary
Eaton N48M28T75SRTRS64X-US Transformer delivers reliable, K-factor nonlinear low-voltage power for industrial facilities. In real-world plants, voltage harmonics and harmonic currents can stress transformers and drive downtime; this unit mitigates those risks with a 75 kVA rating and non-linear design. UL Listed certification and a NEMA 4X enclosure, along with NEMA ST-20 sound provisions, support robust operation in challenging environments. By offering 480 delta to 208Y/120 V transformation with an aluminum winding and accessible tap settings, this transformer reduces commissioning time while delivering consistent performance for control panels and power distribution networks.

FAQs
Yes. This unit is designed for a 480 V delta primary to 208Y/120 V secondary, three-phase operation. Wire the primary to 480 V delta with appropriate overcurrent protection, and connect the secondary to 208Y/120 V circuits with proper grounding. Use the taps: 2 at +2.5% FCAN and 4 at -2.5% FCBN to fine-tune voltage as needed and verify enclosure integrity (NEMA 4X) during installation.
The K-Factor nonlinear design improves tolerance to harmonic currents, reducing overheating and insulation stress under harmonic-rich conditions typical of motor drives and controllers. This translates to more stable voltages, extended winding life, and lower risk of unexpected outages, though the unit itself is listed as 'Efficiency: Exempt,' so performance gains come from harmonic resilience and reliability rather than energy-star style efficiency labeling.
Industries with demanding automation and power distribution needs benefit most, including automotive manufacturing, packaging lines, machine shops, data centers, and process industries. The 75 kVA rating with 480 V to 208/120 V output supports control panels, drives, and critical support equipment, delivering stable supply for high-speed automation, robotics, and sensor networks.
The unit is UL Listed and ships with a NEMA 4X enclosure, offering robust protection in washdown and outdoor environments. It also conforms to standards signposted by NEMA ST-20 for sound ratings, and includes test reports for sound and routine maintenance, aiding regulatory compliance and commissioning.
Maintenance benefits stem from aluminum windings and a rugged CASE D frame that resist corrosion and reduce field maintenance. The unit’s robustness lowers downtime and extends service life, while included test reports speed commissioning. ROI improves through reduced transformer-related interruptions and predictable performance in harsh, high-cycle production environments.
