Eaton X48M28F22CUEEPOS Harmonic Transformer - NEMA TP-1
Part Number: X48M28F22CUEEPOS
Quick Summary
Eaton X48M28F22CUEEPOS harmonic transformer mitigates harmonic distortion in 480 V distribution networks for industrial and commercial systems. This solution targets power quality challenges that lead to nuisance trips, equipment wear, and efficiency losses in demanding facilities. UL Listed, NEMA TP-1 compliant, and designed with copper windings, it also features electrostatic shielding and a robust 115°C rise rating to support reliable operation in hot environments. The transformer’s 225 kVA capacity and 208Y/120 V secondary align with common panelboard and subfeed configurations, while the 2 at +2.5% and 4 at -2.5% taps provide practical voltage regulation. In practice, this isn’t just a component buy; it’s a strategy for uptime, regulatory compliance, and predictable performance across a broad range of loads.

FAQs
Yes. This 225 kVA three-phase dry-type transformer is designed for standard 480 V primary feeds and 208Y/120 V secondary loads, with a 201X wiring connection and a compatible frame (919X). Its voltage taps (+2.5% and -2.5%) support field adjustments during retrofit without significant cubicle modifications, facilitating integration with existing switchgear and panelboards.
The unit is a dedicated harmonic-mitigating transformer rated at 225 kVA, 60 Hz, and three-phase, with 208Y/120 V secondary. Copper windings and an electrostatic shield improve winding integrity and noise control. The 115°C rise rating enables sustained loading, while the NEMA TP-1 efficiency and UL Listing support predictable performance and reliability in data centers and IT rooms.
Ideal for PV integration, commercial power distribution, and industrial facilities with notable harmonic distortion. Its 480 V primary and 208Y/120 V secondary support typical facility distribution architectures, and the optional taps help maintain voltage under load swings common in manufacturing lines and large office complexes.
The transformer is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficient catalog notes. These certifications signify adherence to safety, reliability, and efficiency standards, reducing risk during audits and enabling easier utility and regulatory approvals for projects with strict compliance requirements.
With copper windings and electrostatic shielding, long-term winding protection and reduced insulation degradation lower maintenance frequency. The unit’s efficiency and voltage regulation features translate to lower energy losses and improved system uptime, contributing to a favorable ROI over typical transformer lifecycles in demanding industrial environments.
