Eaton X48M28F33CUEETHRLS52 Harmonic mitigating transformer - UL Listed
Part Number: X48M28F33CUEETHRLS52
Quick Summary
Eaton Harmonic mitigating transformer provides clean power conditioning for critical 480 V to 208Y/120 V distribution networks. Nonlinear loads often create harmonics that overheat equipment, shorten motor life, and raise energy costs, making robust power quality essential. UL Listed safety certification and NEMA TP-1 compliance support reliable installation, while the catalog notes highlight NEMA TP-1 efficiency and a quiet 52 dB operation. With copper windings and a dry-type design, this unit delivers durable performance in indoor and controlled spaces, and the 300 kVA rating supports mid-size loads. The combination of copper windings, adjustable taps, and three-phase 60 Hz operation translates to improved reliability and predictable maintenance for industrial facilities.
