Eaton Specification Sheet - N48M28T22CUEESS
Feature → Business Impact → Application: The K-Factor nonlinear design mitigates harmonic currents, reducing overheating risk and extending transformer life, which translates to lower maintenance costs and higher equipment uptime in environments with nonlinear loads such as VFDs and PLC-driven automation. This supports improved process stability and predictive maintenance programs in manufacturing and material handling facilities. Application: ideal for control panels, drives-heavy lines, and critical power conditioning where uptime is essential. Feature → Business Impact → Application: 225 kVA three-phase rating paired with a 480 V primary and 208Y/120 V secondary delivers precise load transfer and voltage conversion for mixed-output automation systems, enabling seamless integration with MCCs and switchgear while minimizing voltage drop on sensitive equipment. Application: data centers, packaging lines, and process industries requiring dependable sectional power distribution. Feature → Business Impact → Application: Copper windings reduce resistance losses, improving overall efficiency and thermal performance, which lowers operating costs and supports longer service intervals in high-demand environments. Application: heavy-duty mechanical and process industries with continuous operation. Feature → Business Impact → Application: Taps of +2.5% and -2.5% provide voltage-flexibility to compensate for supply swings, supporting stable PLCs, sensors, and motor drives in fluctuating plant conditions. Application: facilities with irregular or long feeder runs. Feature → Business Impact → Application: Grade 304 stainless steel enclosure with NEMA TP-1 compliance and WS37S weather shield offers corrosion resistance and weather protection, reducing enclosure maintenance and enabling outdoor or semi-enclosed installations. Application: outdoor substations, exposed plant rooms, and coastal facilities. Feature → Business Impact → Application: Dimensions and weight (32.65 in L × 36.69 in W × 57.54 in H; ~2159 lb) inform rack, pad, and space planning, ensuring correct clearance, ventilation, and seismic considerations for new-build or retrofit projects. Application: large industrial projects with stringent space planning and safety requirements.

FAQs
Plan for a three-phase installation with a 480 V primary and 208Y/120 V secondary. Verify enclosure mounting (Grade 304 stainless steel, WS37S weather shield), ensure proper grounding, and utilize the +2.5% / -2.5% taps to compensate for voltage fluctuations. Confirm space for airflow and attach to appropriate switchgear or MCCs using standard NEMA TP-1 compliant mounting.
It uses a K-Factor nonlinear design, which is optimized to handle nonlinear harmonic currents without overheating, maintaining performance under heavy VFD and drive-driven loads common in modern manufacturing. This reduces the risk of insulation stress and improves long-term reliability.
Yes. It is UL Listed and NEMA TP-1 compliant, with a corrosion-resistant Grade 304 stainless steel enclosure and WS37S weather shield, making it suitable for harsh or outdoor environments and ensuring compliance with safety and performance standards.
The Grade 304 stainless steel enclosure with WS37S weather shield offers robust corrosion resistance and weather protection, reducing enclosure maintenance while supporting outdoor or semi-enclosed installations. This simplifies site work and improves longevity in challenging plant conditions.
With copper windings and a 225 kVA rating, the unit delivers efficient load handling and lower operational losses, contributing to faster payback through energy savings and reduced downtime. A one-year warranty (or 18 months from shipment) provides initial risk mitigation while supporting long-term maintenance planning.
