Harmonic mitigation at transformer level reduces total harmonic distortion on 480 V primary and 208Y/120 V secondary circuits. Business impact: improved power quality lowers motor and drive overheating, reduces nuisance trips, and supports compliance with harmonic limits in sensitive facilities. Application: ideal for data centers, pharmaceutical plants, and manufacturing lines with multiple VFDs and non-linear loads. Tap changes provide voltage flexibility: taps at +2.5% and -2.5% enable precise voltage matching to bus systems and tolerance of voltage fluctuations. Business impact: stable downstream voltage reduces transformer losses, extends equipment life, and minimizes or eliminates the need for additional voltage regulation. Application: suitable for installations with long feeders, intermittent utility dips, or mixed supply schemes in commercial or industrial buildings. Copper windings deliver high conductivity, low impedance, and robust thermal performance. Business impact: higher efficiency, lower copper losses, and longer service life, with consistent performance across operating conditions. Application: standard in dry-type distribution transformers used in power distribution cabinets and switchgear setups. Dry-type construction with 919X frame and 201X wiring simplifies installation and maintenance. Business impact: safer, easier cooling, smaller footprint, and compatibility with standard mounting footprints and enclosures. Application: fits indoor electrical rooms or outdoor spaces when paired with WS35 weather shield for external installations. Weather protection WS35 and compliance with UL Listed and NEMA TP-1 provide assurance for demanding environments. Business impact: reduces maintenance costs, protects investment, and accelerates regulatory approvals. Application: suitable for commercial facilities and harsh industrial environments requiring reliable, code-compliant power distribution. Warranty and service: Eaton's policy offers one year from installation or eighteen months from shipment, ensuring coverage during critical early operation.

FAQs
Plan for indoor electrical room or outdoor installation using WS35 weather protection. Ensure clearance for the 75 in height, 44.2 in width, and 36.23 in depth; verify mounting to the 919X frame and 201X wiring connections. Use conformant wire sizing and appropriate protective devices. Allow access for service and future tapping adjustments at +2.5% and -2.5%.
The unit supports a 225 kVA rating with a 60 Hz, three-phase configuration, 480 V primary and 208Y/120 V secondary. It features copper windings, 0° phase shift, taps at +2.5% and -2.5%, a 150 °C rise, and a 200 °C insulation system. These factors together minimize harmonic distortion and improve overall power quality in non-linear loads.
Yes. The X48M28T22CUEENON provides harmonic mitigation and clean power essential for data centers, manufacturing lines with multiple VFDs, and other electronics-heavy facilities. Its three-phase 480 V to 208Y/120 V output, copper windings, and WS35 weather protection make it versatile for indoor and outdoor installations within industrial power management ecosystems.
The transformer is UL Listed and NEMA TP-1 compliant, with a 150 °C rise rating. These certifications ensure safety, reliability, and compliance with industry standards for performance and efficiency. NEMA TP-1 efficiency notes on the catalog further support energy-conscious design and operating cost reduction in power distribution systems.
Warranty coverage follows Eaton policy: one year from installation or 18 months from shipment, whichever occurs first. The copper windings, robust insulation, and weather protection reduce maintenance needs and extend equipment life. The improved power quality also lowers downtime and energy waste, contributing to favorable total cost of ownership in facilities with high non-linear loading.
