Eaton X48M28T22TCUEENON Harmonic transformer - NEMA TP-1
Part Number: X48M28T22TCUEENON
Quick Summary
Eaton Harmonic mitigating transformer is designed to reduce harmonic distortion in industrial power systems for clean, reliable operation. In facilities with nonlinear loads, voltage variation and overheating can trigger equipment trips and downtime, threatening production targets. UL Listed, NEMA TP-1 compliant, and NEMA TP-1 efficient certifications underpin safety, performance, and energy efficiency in demanding environments. With a 225 kVA rating and copper windings, it supports scalable power quality improvements for 480 V primary and 208Y/120 V secondary, balancing performance with cost and footprint. Designed for 60 Hz operation and zero phase shift, it integrates with standard distributions while the 150 °C rise and 200 °C insulation system deliver dependable operation even in hotter installations. The rugged construction and Weathershield option simplify outdoor or harsh-indoor deployments and reduce enclosure needs.

FAQs
The X48M28T22TCUEENON is a three-phase dry-type transformer rated for 480 V primary and 208Y/120 V secondary. For installation, ensure proper enclosure (Weathershield WS35 where required), confirm wiring on 201X connections, and observe the 60 Hz supply. Verify clearance for heat dissipation due to the 150 °C rise and use appropriate mounting to support a 225 kVA load. Follow UL Listed requirements and local electrical codes.
This transformer provides harmonic mitigation through its copper-wound design, reducing harmonic currents entering the distribution network. The result is lower overall losses, reduced overheating, improved motor and drive life, and fewer nuisance trips. It is well-suited for facilities with nonlinear loads such as motor drives, inverters, and high-density electronics.
Yes. The unit is UL Listed and NEMA TP-1 compliant and efficient, meeting established safety and performance criteria for energy distribution equipment. This combination supports regulatory compliance, reliable operation in demanding environments, and energy-efficient performance for long-term operating costs.
The transformer offers two taps at +2.5% and four taps at -2.5% to adjust voltage under varying load and supply conditions. Use these taps to maintain output within tolerance during startup surges, grid swings, or long cable runs. Properly configuring taps can reduce voltage-related stress on downstream equipment and improve overall power quality.
The unit carries Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. This reduces risk for procurement and project teams, while the UL Listing, NEMA TP-1 compliance, and robust enclosure options help minimize maintenance downtime and enclosure costs, contributing to lower total cost of ownership and faster ROI.
