Copper windings and a robust dry-type construction reduce I²R losses and improve short-term surge handling, delivering higher efficiency and cooler operation. This translates into longer transformer life and lower maintenance costs in hot, crowded electrical rooms. The ability to fine-tune voltage with 2 taps at +2.5% and 4 taps at -2.5% minimizes voltage fluctuations, reducing equipment stress and nuisance tripping in facilities with variable loads. With a 150 kVA rating and a 480 V primary feeding a 208Y/120 V secondary, it seamlessly integrates with standard distribution panels and control circuits, supporting scalable expansions without rewriting upstream wiring. Electrostatic shielding and WS34 weather protection enhance reliability in retrofit projects and outdoor installations. UL Listed and NEMA TP-1 compliant, the unit meets rigorous reliability and efficiency standards while offering easy procurement and predictable performance. A copper-winding, frame 918A build delivers robust mechanical strength for demanding environments, while a 60 Hz, three-phase design supports widespread industrial use. The 150 °C rise rating and 200 °C insulation system provide a strong protection margin in hot facilities, reinforcing long-term asset health and uptime.

FAQs
Plan for a three-phase installation at 60 Hz with a 480 V primary and 208Y/120 V secondary. Use the 200X wiring connection and accommodate the transformer’s 1978 lb weight with proper crane or mounting hardware. Allow space for the WS34 weathershield if used outdoors, and follow UL guidelines for access and ventilation to maintain the 150 °C rise margin.
This transformer is designed as a harmonic mitigating device with a 15° phase shift, copper windings, and precise tap settings. By smoothing waveform distortions, it lowers THD and reduces stress on downstream equipment, decreasing nuisance trips and extending life of drives and sensors in manufacturing lines and data centers. UL Listed and NEMA TP-1 compliant standards support reliable operation in regulated environments.
The X48M28T49CUEEPOS is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficiency considerations noted in catalog documentation. These certifications ensure compliance with safety and energy efficiency requirements for industrial power distribution. This helps with procurement approvals, insurance considerations, and meets code expectations for commercial and manufacturing installations, reducing project risk.
Yes. With a 150 kVA rating and a stable 480 V to 208Y/120 V secondary, this dry-type transformer provides clean power for sensitive IT and control systems. Its harmonic mitigation capability minimizes distortion on critical rails, while copper windings and robust insulation support reliable operation in controlled environments like data centers and server rooms.
Deploying the X48M28T49CUEEPOS can lower maintenance costs through reduced heating and wear from harmonics, extend equipment life, and improve uptime in mission-critical applications. The UL Listed and NEMA TP-1 compliant design simplifies procurement and commissioning, while the 150 kVA rating supports scalable growth without frequent replacements or rewiring in growing facilities.
