Eaton N48M28T1521 K-Factor transformer - UL Listed
Part Number: N48M28T1521
Quick Summary
K-Factor transformer is a three-phase nonlinear ventilated transformer designed to mitigate harmonic distortion in industrial power systems. For engineers balancing sensitive loads, harmonics from variable-speed drives and large motors can cause overheating, voltage distortion, and unexpected equipment trips. This Eaton N48M28T1521 carries UL Listed certification and a K13 K-Factor rating, with a vented design that enhances cooling in cabinet or room installations. By addressing harmonic currents at the distribution point, it helps protect downstream gear and reduce maintenance costs. Ideal for automation, manufacturing, and data-center adjuncts, it supports reliable power quality while integrating with standard 480V to 208Y/120V systems.

FAQs
The transformer has a 480 V primary and a 208Y/120 V three-phase secondary, making it compatible with standard plant distribution and switchgear. Its UL Listed status supports compliance, while its 430 lb weight and vented design influence placement, mounting, and cabinet clearances to ensure reliable cooling and servicing.
K-Factor indicates the transformer’s ability to handle harmonic currents from non-linear loads. A K13 rating signifies its suitability for moderate to higher harmonic content, reducing heating and voltage distortion at the distribution point, which helps protect downstream equipment.
Yes. The 15 kVA, three-phase, K-Factor design is intended for non-linear loads such as VFDs and other drives. It mitigates harmonics at the source, lowers overheating risk, and supports stable voltage for connected equipment in manufacturing lines.
The transformer is UL Listed, confirming safety and compliance for industrial installations. This certification simplifies procurement, reduces commissioning risk, and aligns with typical electrical safety standards in automation environments.
Installation benefits include a vented design for improved cooling, a compact footprint, and clear dimension data for planning. ROI benefits arise from reduced harmonic heating, longer insulation life, lower maintenance, and fewer unplanned outages in drives-heavy, automated facilities.
