Copper windings and a 45 kVA rating deliver high current capacity with robust thermal stability, resulting in lower copper losses and steadier voltages under heavy load. In practice, this means reduced energy costs and fewer voltage excursions for sensitive equipment such as drives and controllers. The 60 Hz three-phase design with a -30° phase shift mitigates harmonics at the source, improving power quality for critical automation equipment and reducing nuisance trips on sensitive loads. Tap settings of 2 at +2.5% and 4 at -2.5% enable fine voltage regulation to match system conditions, protecting motors and electronics from overvoltage or undervoltage events and simplifying panel integration. The dry-type construction with copper windings, frame 915D, and optional WS39 Weathershield provides durability in both indoor and restricted spaces, while electrostatic shielding further minimizes noise and EMI. At 630 lb, a compact footprint and clear wiring connections (230X) support straightforward installation and service access in retrofit projects or new builds. Compliance with UL Listed and NEMA TP-1 standards, plus the catalog note for NEMA TP-1 efficiency, helps ensure safe operation and regulatory alignment, reducing risk during inspections and procurement.

FAQs
This transformer is a dry-type, three-phase device with a 480 V primary and 208Y/120 V secondary, designed for 60 Hz systems. Plan for the 915D frame footprint, 22 in depth, 29 in width, and 39 in height, and account for the 630 lb weight to ensure proper mounting, clearance, and service access. Use 230X wiring connection and consider WS39 weathershield if outdoor placement is required.
Key specs include a -30° phase shift and a 45 kVA rating with copper windings, which collectively reduce harmonic distortion in the supply to sensitive loads such as drives and controls. The unit operates at 60 Hz and supports 480 V input with 208Y/120 V output, aiding compliance with power quality requirements in modern facilities.
Yes. The X48M28B45CUEETHR is UL Listed and NEMA TP-1 compliant, with a catalog note indicating NEMA TP-1 efficiency. These certifications support safe operation, code compliance, and eligibility for procurement in regulated environments.
Best suited for industrial power distribution where harmonic sensitivity is a concern—such as drives, inverters, and automation controllers—in facilities powered by 480 V three-phase systems. The 208Y/120 V secondary is ideal for control panels, sensing circuits, and auxiliary loads, while the robust construction supports retrofit or new builds in manufacturing, data centers, and process automation.
The unit is covered by Eaton's warranty policy (25-000) offering one year from installation or eighteen months from shipment, whichever occurs first. Regular inspection of terminations, mounting security, and temperature rise indicators is recommended. UL/NEMA certifications and the electrostatic shielding help minimize EMI-related issues and long-term maintenance costs.
