Copper windings in a dry-type distribution transformer deliver higher efficiency and lower loss compared to laminated alternatives, translating to cooler operation and reduced energy costs in high-load installations. Feature → Business Impact → Application: copper windings reduce copper loss and heat, improving reliability for critical loads such as motor drives and programmable logic controllers; ideal for manufacturing lines and data centers where uptime matters. Tap settings provide +2.5% / -2.5% regulation, enabling precise voltage control under fluctuating loads, which minimizes equipment misoperation and protects sensitive electronics in 480 V to 208Y/120 V downstream circuits. The 150 kVA rating supports scalable expansion while keeping footprint manageable in switchgear rooms, making it suitable for mid-range distribution needs. Compliance with NEMA TP-1 and UL Listing reduces procurement risk and accelerates project approvals, while the 150°C rise insulation ensures robust performance in moderately hot environments. The electrostatically shielded design and WS34 weather shield enhance reliability in exposed or semi-enclosed spaces, easing installation in industrial facilities with limited enclosure options. Three-phase operation at 60 Hz with zero phase shift simplifies integration with existing power distribution and minimizes neutral-related issues, delivering a smoother power profile for sensitive loads such as servers, CNC equipment, and HVAC controls.

FAQs
Yes. This transformer is designed for a 480 V three-phase primary with a 208Y/120 V secondary. Ensure the wiring connection is set to 200X, verify the ambient conditions conform to dry-type install requirements, and confirm the 60 Hz electrical specification aligns with the facility panel schedule. The unit’s taps accommodate voltage regulation during load changes.
Key specs include a 150 kVA rating, 480 V primary, 208Y/120 V secondary, 60 Hz operation, and a zero degree phase shift. The +2.5% / -2.5% taps provide precise voltage regulation to minimize harmonic propagation and voltage distortion downstream, improving equipment performance and reducing thermal stress on connected loads.
Absolutely. Its dry-type construction with copper windings and UL listed, NEMA TP-1 compliant design makes it reliable for data centers, manufacturing floors, and commercial facilities. The electrostatically shielded coil and WS34 weather shield support stable operation in varied spaces, while the 150 kVA rating accommodates typical data hall or line-side distribution needs.
The X48M28T49CUEENON is UL Listed and NEMA TP-1 compliant, reflecting safety and efficiency standards for power distribution equipment. Its 150°C insulation rise with a 200°C insulation system supports robust performance, and the catalog notes emphasize NEMA TP-1 efficiency characteristics, assisting compliance audits and procurement sign-offs.
Maintenance for this dry-type transformer is typically lower than oil-filled units due to reduced leakage and cooling requirements. It carries Eaton’s warranty policy of one year from installation or eighteen months from shipment. ROI is enhanced by improved power quality, reduced outages, and lower maintenance costs from fewer cooling and containment concerns in dry environments.
