The X48M28T12CUEETHR offers a robust 112.5 kVA rating, providing ample headroom for mid-size plant loads and PV-related applications while allowing fewer transformers on site and reducing installation footprint. Copper windings deliver improved conductivity and thermal performance, translating into higher overall efficiency and longer life in demanding environments. With 480 V primary and 208Y/120 V secondary, three-phase 60 Hz operation supports common industrial and controls architectures, ensuring compatibility with standard switchgear and panelboards. Tap changes at 2 at +2.5% and 4 at -2.5% help maintain voltage balance under fluctuating line conditions, minimizing voltage drift and equipment stress. The unit’s 150 °C rise and 200 °C insulation system enable reliable operation in hotter plants or spaces with limited cooling capacity. Weathershield WS34 and electrostatic shielding add resilience against weather, EMI, and outdoor exposure, reducing maintenance and shielding sensitive electronics. Weight and footprint considerations are real; plan for the 1982 lb system, the footprint (24.67 in depth, 30.61 in width, 56.17 in height), and appropriate lifting, clearance, and ventilation to maximize uptime. System compatibility with Frame 917 and Wiring connection 203X ensures straightforward integration into existing Eaton-based architectures, while UL Listed and NEMA TP-1 compliant features simplify procurement, installation, and regulatory alignment. This transformer is well-suited for PV-driven facilities, manufacturing lines, and distribution panels seeking harmonics mitigation without compromising on reliability or maintainability.

FAQs
This transformer uses a 480 V primary and 208Y/120 V secondary to align with common industrial panels. With a frame 917, wiring connection 203X, and a dry-type construction, it fits typical Eaton distribution schemes. Plan for the 24.67 in L, 30.61 in W, 56.17 in H footprint and the 1982 lb weight, ensuring adequate clearance, lifting arrangements, and ventilation for safe, code-compliant installation.
Verify the 112.5 kVA rating, 60 Hz frequency, three-phase operation, and phase shift of −30°. Confirm copper windings and the 150 °C rise with a 200 °C insulation system. Check the taps: 2 at +2.5% and 4 at -2.5%. Ensure primary voltage of 480 V and secondary of 208Y/120 V to match system voltages and harmonic mitigation requirements.
Yes. The unit’s 480 V to 208Y/120 V output suits PV inverters and plant controls, providing harmonic mitigation and stable voltage under varying loads. The electrostatically shielded construction and Weathershield WS34 option extend reliability in outdoor or harsh environments, while NEMA TP-1 efficiency supports compliant operation in modern power systems.
The transformer is UL Listed and NEMA TP-1 Compliant, with NEMA TP-1 efficiency features. These certifications support safety, reliability, and regulatory acceptance in many regions. The included warranty (one year from installation or eighteen months from shipment) also helps manage risk and total cost of ownership.
Copper windings and robust insulation yield durable operation with lower failure risk in harsh environments. The electrostatic shielding and weather resistance reduce EMI concerns and outdoor upkeep. Higher reliability translates to reduced downtime, lower maintenance costs, and improved equipment availability, contributing to a favorable return on investment for facilities with stringent power-quality needs.
