Eaton Specification Sheet - N48G28T12CUEE
Feature → Business Impact → Application: The N48G28T12CUEE delivers 112.5 kVA with a 480 V primary and 208Y/120 V secondary, enabling capable load distribution for mid‑sized industrial control panels and machine zones, reducing the need for multiple smaller transformers and cutting installation footprint. This translates to lower material and labor costs during panel builds and easier future scalability in manufacturing lines. Feature → Business Impact → Application: Copper windings and robust construction provide higher efficiency and durable performance under continuous cycling, reducing winding temperature rise and maintenance cycles for HVAC‑challenged environments, which is critical in drive-intensive applications with variable loads. Feature → Business Impact → Application: K‑Factor nonlinear ventilated design mitigates distortion from harmonic currents common with VFDs and drives, improving panel power quality, extending component life, and reducing nuisance trips in automation architectures. Feature → Business Impact → Application: Tap changer 2 at -5% FCBN offers voltage regulation to compensate for supply fluctuations, preserving output voltage at sensitive PLCs and motor starters, which lowers risk of under‑ or over‑voltage faults in remote or fluctuating sites. Feature → Business Impact → Application: Weathershield WS19 and rugged enclosure compatibility enable outdoor or harsh‑environment installations, delivering reliable protection against dust, moisture, and temperature swings in outdoor substations or exposed equipment rooms. Feature → Business Impact → Application: UL Listed and NEMA TP‑1 efficiency confirm compliance and energy performance, supporting procurement requirements, rebates, and sustainability programs across manufacturing campuses and data‑driven facilities.

FAQs
The transformer is designed for standard industrial enclosures and panel spaces. Ensure adequate clearance for cooling and access for taps (-5% at FCBN) and connect with copper windings and the 916A frame. Verify enclosure IP rating and ambient temperature comply with NEMA TP‑1 guidelines.
K‑Factor nonlinear ventilated transformers suppress harmonic flux impacts by design, improving voltage regulation and reducing overheating. This translates to lower thermal stress on windings and better power quality in drives‑heavy applications such as conveyors and machine tools.
Yes, with WS19 weather shielding and rugged construction, the N48G28T12CUEE is appropriate for outdoor or exposed indoor installations, provided enclosure protection and cooling are maintained and rated for the site environment.
This unit is UL Listed and NEMA TP‑1 compliant, with a 150 °C rise and 200 °C insulation system, ensuring safety, efficiency, and regulatory alignment for industrial power distribution.
Expected benefits include reduced energy losses due to NEMA TP‑1 efficiency, lower maintenance frequency from robust copper windings, and improved uptime from reliable voltage regulation and harmonic handling in motor control and automation panels.
