Feature: Harmonic mitigating design reduces input current distortion and neutral currents in the supply, delivering cleaner, more stable power. Business impact: lower transformer losses and reduced cooling requirements translate into measurable energy savings and longer equipment life. Application: ideal for non-linear loads such as VFDs, servo drives, and switched-mode power supplies on manufacturing lines or data centers. Paragraph 2: Feature: 300 kVA three-phase rating with 480 V primary and 208Y/120 V secondary and zero phase shift. Business impact: balanced voltage at critical loads, improved protection coordination, and less equipment stress under peak demand. Application: supports IT, automation, and process equipment requiring consistent voltage and fast response to load changes. Paragraph 3: Feature: Rugged NEMA 2 enclosure and FR945 frame with floor mounting. Business impact: reliable installation in industrial environments with predictable heat dissipation and service access, minimizing downtime. Application: suitable for floor-mounted transformer rooms or dedicated power modules in manufacturing plants. Paragraph 4: Feature: Copper windings and 280 °C insulation rating for high thermal tolerance and long service life. Business impact: improved efficiency and durability under heavy, continuous operation, reducing replacement intervals. Application: heavy-load applications with frequent starts, ramps, or harmonic content, such as motors and drives. Paragraph 5: Feature: Tap changers 2 at +2.5%, 4 at -2.5% and 200X wiring connections. Business impact: on-site voltage regulation and flexible configurations to match site swings, lowering commissioning costs. Application: retrofit and new builds where site voltage varies across feed sources. Paragraph 6: Feature: DOE2016 Efficient compliance and UL listing with a NEMA ST-20 sound spec. Business impact: regulatory alignment, potential utility incentives, and safer, quieter operation. Application: procurement-ready for regulated industries and facilities aiming to minimize energy waste.

FAQs
The X48M28T3316CUNON is designed for three‑phase applications with a 480 V primary and 208Y/120 V secondary, delivering a 0° phase shift and stable outputs for critical loads. This makes it ideal for data centers, manufacturing lines, and automation-heavy facilities where harmonics from drives and switches can impact downstream equipment.
The transformer weighs 2735 lb and has dimensions of 33.5 in (depth) by 66.18 in (height) by 42.18 in (width). As a floor-mounted unit, plan for sufficient clearance for service access and routing, plus safe lifting arrangements. The rugged FR945 frame supports stable, long-term installation in industrial spaces.
This Eaton transformer is UL Listed and meets DOE2016 Efficient standards for energy performance. It aligns with catalog notes referencing 10 CFR Part 431 (2016) Efficient, supporting regulatory compliance and potential incentive qualification for energy-conscious projects.
Harmonic mitigation reduces distortion in the input current, lowering thermal stress and improving power factor. This model achieves mitigation through its design and copper windings, paired with precise voltage taps, enabling cleaner outputs to drives, motors, and digitized controls, resulting in longer equipment life and reduced cooling needs.
Expect energy savings from DOE2016 efficiency, lower maintenance due to reduced harmonic stress, UL safety assurance, and durable NEMA 2 protection. On-site tuning with the 2 at +2.5% and 4 at -2.5% taps, plus the 200X connection, simplifies commissioning and reduces the risk of voltage excursions that could impact uptime.
