Feature: Harmonic mitigating transformer design improves power quality and reduces waveform distortion. Business Impact: Lowered risk of equipment overheating and premature failure, improved RFO (return-on-frequency) for high-load facilities. Application: Data centers and automated manufacturing lines where harmonic currents from drives and controllers are common. Feature: Copper windings and robust insulation deliver durable, low-loss performance. Business Impact: Enhanced thermal stability and longer service life with predictable maintenance windows. Application: High-load distribution banks in industrial plants requiring dependable COP (cost of ownership) metrics. Feature: Voltage tapping with two taps at +2.5% and four taps at -2.5% enables tight voltage regulation. Business Impact: Reduces voltage-related derating and equipment stress, enabling tighter controls on downstream equipment. Application: Facilities with fluctuating input voltages or sensitive equipment that needs stable 208Y/120 V secondary. Feature: NEMA TP-1 efficient and UL Listed with electrostatically shielded construction. Business Impact: Compliance assurance, safety, and reduced energy waste across operations. Application: Commercial and industrial environments with strict regulatory expectations and outdoor or harsh conditions (Weathershield WS35). Feature: 225 kVA rating with a 480 V to 208Y/120 V output, three-phase, 60 Hz, 15° phase shift. Business Impact: Scalable power distribution for critical systems, enabling modular growth without transformer replacements. Application: Large machine cells, distribution centers, and mission-critical loads that demand reliable power transfer.Feature: Physical attributes and mounting compatibility (frame 919X, wiring connection 201X). Business Impact: Easier installation, standardized footprint, and straightforward retrofits or expansions. Application: Retrofit projects or new builds where space, access, and wiring schemes matter for quick commissioning.

FAQs
When planning installation, confirm a three-phase 480 V primary supply and a 208Y/120 V secondary circuit. Verify clearance around the frame 919X, wiring connection 201X, and the overall footprint, which measures 36.23 in by 75 in by 44.2 in. Ensure the site can support the 3450 lb weight and that ambient conditions meet the device’s 150 °C rise rating and Weathershield WS35 suitability for outdoor or harsh environments.
The transformer is designed as a harmonic mitigating device with a 15° phase shift to help manage non-linear loads. It operates at 60 Hz in a three-phase configuration, delivers 225 kVA, and uses copper windings to minimize energy losses. The dual +2.5% and four -2.5% taps allow precise voltage control under fluctuating loads, reducing harmonic-induced overheating and improving downstream equipment performance.
Yes. The X48M28T22CUEEPOS carries UL Listed certification and is NEMA TP-1 compliant, with catalog notes indicating NEMA TP-1 efficiency. This combination ensures regulatory compliance, safer operation, and optimized efficiency for continuous service in industrial environments where power quality is critical.
Industries with significant harmonic-producing loads, such as data centers, plastics and metal forming, and automated manufacturing facilities, gain the most. The transformer’s harmonic mitigation, voltage regulation taps, and robust protection features help protect sensitive drives and controls, improve uptime, and reduce energy waste—delivering a strong return on investment in complex electrical ecosystems.
The unit carries Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. Maintenance requirements are typical for dry-type transformers with copper windings, including periodic inspection of insulation, connections, and cooling paths. The electrostatically shielded design and robust enclosure minimize routine maintenance, contributing to lower lifecycle costs and predictable performance.
