Eaton Specification Sheet - X48M28F49TCUEENEG
Copper windings and dry-type construction deliver high efficiency and thermal robustness, with a 115 °C rise rating and a thermal indicator to support proactive maintenance. This translates to reduced copper losses, better uptime, and predictable performance in manufacturing, data centers, or utilities where continuous operation matters. Tap settings provide 2 taps at +2.5% and 4 taps at -2.5%, enabling precise voltage regulation for a 480 V primary and 208Y/120 V secondary, which minimizes voltage stress on sensitive equipment and reduces nuisance trips in PV and critical loads. The transformer is a three-phase, 60 Hz device with a -15° phase shift, designed to mitigate harmonics and improve overall power quality, especially in systems with nonlinear loads. It includes electrostatic shielding and a WS34 weather shield, making it suitable for indoor and outdoor installations while limiting electromagnetic interference and environmental exposure. With a 150 kVA rating, copper windings, and a robust 918A frame, the unit offers strong compatibility with standard field mounting, wiring (200X), and integration into existing switchgear. The UL Listed and NEMA TP-1 compliant certifications, along with a defined warranty, simplify procurement, compliance, and service planning, delivering long-term value and predictable return on investment.

FAQs
Plan for a three-phase 480 V input with a 208Y/120 V secondary and 60 Hz operation. Ensure adequate clearance for the 1800 lb unit, space for wiring 200X connections, and proper enclosure protection with WS34 weather shield if installed outdoors. Consider thermal indicator access for routine checks and ensure mounting on a stable base compatible with the 918A frame.
The transformer provides 2 taps at +2.5% and 4 taps at -2.5%, enabling fine-tuned voltage regulation at the 208Y/120 V secondary when the 480 V primary fluctuates. This helps maintain consistent output to sensitive loads, reduces voltage distortion, and minimizes nuisance trips during load swings common in PV arrays and manufacturing lines.
Yes. This unit is UL Listed and NEMA TP-1 compliant, with additional notes indicating NEMA TP-1 efficiency. These certifications ensure compliance with safety and performance standards critical for industrial, commercial, and utility-scale power distribution applications.
The transformer is rated 150 kVA, operates at 60 Hz, and is a three-phase device with a -15° phase shift. Primary voltage is 480 V, and secondary voltage is 208Y/120 V. It features copper windings, a 115 °C rise, and a thermal indicator to support maintenance planning and uptime in demanding environments.
Warranty terms state one year from installation or eighteen months from shipment, whichever comes first. This, along with UL/NEMA certifications and the rugged WS34 weather shield, supports predictable service planning, reduces lifecycle risk, and helps justify total cost of ownership in capital projects.
