Eaton Specification Sheet - X48M28F45I4CUEENON
Three-phase 480 V input with 208Y/120 V secondary and a 45 kVA rating ensures compatibility with common plant distributions, enabling tighter load balance and improved power quality across data centers, manufacturing lines, and commercial spaces. Copper windings and a 115 °C rise design provide robust thermal performance, supporting continuous operation under nonlinear loading while delivering lower resistance losses and longer life in demanding environments. The tap scheme includes 2 taps at +2.5% and 4 taps at -2.5%, allowing precise voltage regulation to keep secondary voltage within tolerance as loads fluctuate, reducing downstream equipment stress and fault risk. Electrostatic shielding enhances EMI control, while the WS39 weather shield option expands outdoor or harsh-environment installation options, minimizing protective enclosures and reducing downtime. Compliance and efficiency are reinforced by UL Listed status and NEMA TP-1 efficient design, helping facilities meet evolving energy and safety standards while controlling energy costs over the life of the asset.

FAQs
Plan for a three-phase, 480 V input with a 208Y/120 V secondary and reserve space for a 22 in depth, 39 in height, and 29 in width footprint. Ensure adequate ventilation for the 115 °C rise rating, access for copper windings, and compatibility with a 4-in window for connections. Opt for the WS39 weather shield if outdoor installation is anticipated.
The unit is 60 Hz, three-phase, with a 45 kVA rating and zero phase shift (0°). Primary voltage is 480 V and secondary is 208Y/120 V, suitable for harmonically active loads such as VFDs and nonlinear equipment. The +/− tap range (+2.5% and −2.5%) supports voltage regulation under dynamic loading, maintaining stable secondary voltage for critical equipment.
Yes, it is designed to mitigate harmonics in environments with nonlinear loads, improving power quality and protecting sensitive equipment. Copper windings and robust thermal performance support continuous operation, while the three-phase 480 V input aligns with common facility power systems. The WS39 weather shield option expands deployment in challenging environments without sacrificing performance.
The transformer is UL Listed, confirming safety and conformity to recognized standards. It also features NEMA TP-1 efficiency considerations, signaling energy-efficient design suitable for compliance-focused projects. These certifications help streamline procurement, reduce risk during audits, and support long-term operational cost savings.
With copper windings and solid thermal margins, maintenance needs are typically modest, focusing on enclosure integrity and connection checks. The 18-month shipment warranty or one-year installation warranty reduces risk during early operation. The combination of improved power quality, reduced downtime, and energy efficiency supports faster ROI in facilities with high harmonic loads.
