Eaton Specification Sheet - X48M28F12TCUEEPOS
Harmonic mitigation design reduces distortion at the source, improving power quality and reducing stray heating in feeders and switchgear. This translates into measurable energy savings, cooler operation, and longer life for connected equipment in PV plants and manufacturing lines. The utility of copper windings and a robust 115°C rise rating supports durability under high ambient temperatures and continuous operation, reducing replacement cycles and service calls. Voltage regulation with taps (+2.5%, -2.5%) helps maintain secondary voltage within spec as loads vary, minimizing device stress and facilitating compliance with utility voltage tolerances. The 480 V to 208Y/120 V three‑phase configuration and 60 Hz operation ensure broad compatibility with common industrial equipment and PV inverters, while the 200X wiring connection and frame 917 footprint streamline on‑site installation. Electrostatic shielding adds an extra layer of safety against insulation degradation in harsh environments, and the optional WS34 Weathershield supports outdoor applications without compromising performance. UL Listed and NEMA TP‑1 efficient, this transformer meets essential safety and efficiency standards while delivering predictable long‑term performance.
