Eaton X48M28T33CUEENEG Harmonic Transformer - UL Listed

Harmonic mitigation design is engineered to reduce distortion and improve overall power quality, which translates to fewer trips, longer equipment life, and reduced maintenance costs for drives and converters in manufacturing lines. This feature directly benefits facilities deploying high-harmonic loads such as motor drives and PV inverters, enabling compliant operation under demanding electrical environments. The 480 V to 208Y/120 V three-phase configuration provides a standardized distribution path for both critical loads and auxiliary equipment, simplifying panel layouts and improving system reliability. Copper windings paired with a 150 °C rise insulation system deliver robust thermal performance, enabling consistent output in hot environments and lowering cooling requirements in tight plant spaces. The transformer offers voltage-tap flexibility—two taps at +2.5% and four taps at -2.5%—to accommodate modest supply variations, reducing the need for additional voltage regulators and improving uptime. As a dry-type unit with Weathershield WS35 and electrostatic shielding, installation is safer outdoors or in exposed environments, and maintenance intervals are extended due to enhanced insulation and low oil management risk. Compliance with NEMA TP-1 and UL Listed standards ensures safety, while the NEMA TP-1 efficient catalog notes reinforce energy performance expectations. These features collectively support faster project commissioning, predictable performance, and lower lifecycle costs for industrial facilities using dry-type distribution transformers in spaces constrained by footprint and thermal load.
