The K-Factor nonlinear design coupled with a vented XFMR enclosure minimizes temperature rise under harmonic-rich loads, improving reliability in continuous operation. This translates to longer transformer life, reduced maintenance intervals, and more predictable voltage stability for critical loads. Applications include data centers, machine controls, and process automation where variable demand and harmonics challenge traditional transformers. With a 15 kVA rating and three-phase configuration at 480-208Y/120, the unit supplies reliable secondary voltages for control panels and feeders while preserving a compact footprint. Its 21.13 in L x 36.88 in H x 24.88 in W footprint and 430 lb weight influence installation planning and rack/panel integration; it's designed for spaces with typical industrial clearances. Ventilated XFMR design supports efficient heat dissipation in confined spaces, enabling safer operation and easier airflow management in cabinets and electrical rooms. K13 variant indicates a specific K-Factor profile suitable for moderate to high harmonic loads. UL Listed certification supports safety, reducing audits, and the transformer is a rugged, reliable choice for demanding environments.

FAQs
Yes. The N48M28T1521CUI3 is a three-phase, 15 kVA transformer with a 480-208Y/120 secondary, designed for industrial controls and automation panels. It measures 21.13 in long, 36.88 in high, and 24.88 in wide, and weighs about 430 lb, so plan for robust mounting and clearances. The UL Listed certification supports safety compliance, and the included Eaton specification sheet provides installation notes and wiring guidance.
Under harmonic-rich loads, the K-Factor nonlinear design reduces peak temperature rise and limits overheating, which translates to more stable voltages and extended service life. The vented XFMR construction further enhances heat dissipation, enabling reliable operation in environments with limited cooling. This improves overall efficiency and reduces planned maintenance intervals for critical production lines.
Industries such as automotive manufacturing, packaging, process control, and data-center support equipment benefit from this transformer, especially where variable loads and harmonic currents are common. The 15 kVA, three-phase rating supports mid-sized power distribution and control circuits without oversized spacing. Its compact yet rugged form suits retrofit projects and new installations in existing electrical rooms.
This model is UL Listed, meeting safety standards for industrial equipment. The Eaton Specification Sheet N48M28T1521CUI3 contains wiring diagrams, mounting clearances, cooling considerations, and voltage ratings to support compliance audits and sourcing. Use the spec sheet as the primary reference for panel integration, especially when creating bill of materials, mechanical drawings, and maintenance procedures.
Adopting this transformer can improve ROI through reduced downtime, fewer unplanned outages, and steadier voltage delivery under harmonic loads. The K-Factor nonlinear design lowers operating temperature, enabling longer service life and less frequent maintenance. UL Listed safety reduces inspection time, and the vented XFMR enclosure supports better cooling, potentially lowering cooling costs in crowded electrical rooms.
