Feature → Business Impact → Application: K-Factor nonlinear design with an electrostatic copper shield reduces harmonic distortion and enhances short-circuit resilience, delivering cleaner power and lowering customer risk during faults. This translates to higher equipment life and fewer unplanned outages on critical drives and motors in manufacturing lines. Application: motor control centers and drive systems where harmonic mitigation is important and regulatory alignment matters. Feature → Business Impact → Application: 112.5 kVA three-phase rating with 480 V primary and 208Y/120 V secondary simplifies integration into existing plant feeders and panel boards, reducing commissioning time and providing predictable voltage transfer for sensitive loads. Application: CNC machines, presses, and assembly lines requiring consistent voltage profiles. Feature → Business Impact → Application: taps at ±2.5% to accommodate slight distribution voltage variations, enabling tighter control of downstream equipment and smoother startup/stop sequences. Application: hospitals, data centers, and process plants with fluctuating feeder voltages. Feature → Business Impact → Application: aluminum winding and rugged EE frame 916A, along with WS19 weather shielding, support durable outdoor and harsh indoor environments, lowering maintenance costs and extending service life. Application: outdoor transformer enclosures and exposed installations. Feature → Business Impact → Application: warranty policy and factory documentation provide confidence for procurement and lifecycle planning, helping justify total cost of ownership and ROI during the acquisition phase. Application: procurement projects with strict vendor governance and maintenance expectations.

FAQs
Yes. The N48M28T12EECS is designed for 480 V primary and 208Y/120 V secondary in a three‑phase, 60 Hz configuration. Wiring uses 283B connections and the unit features an EE frame (916A), which supports mounting in standard electrical rooms and panel boards. Verify enclosure clearance and mounting provisions per site requirements during installation.
Key specs include a 112.5 kVA volt-ampere rating, 480 V primary, 208Y/120 V secondary, three-phase configuration, 60 Hz, and a 150 °C rise with a 200 °C insulation system. It also features taps at ±2.5% to adjust voltage under load. The device uses a K-Factor nonlinear design and includes an electrostatic copper shield for improved performance.
Yes, its nonlinear K-Factor design, electrostatic copper shield, and robust insulation make it well suited for motor drives and critical loads in data centers or manufacturing environments. The 112.5 kVA rating supports medium‑sized power paths, and the WS19 weather shield option enhances outdoor reliability where ambient conditions vary.
Certifications are listed as 'Contact Manufacturer' in the dataset, so confirm region-specific certifications (CE, SIL, IP) with Eaton. Catalog notes indicate NEMA TP-1 efficiency; verify compliance with your local electrical codes and customer requirements during procurement and final design reviews.
Warranty covers one year from installation or 18 months from shipment, whichever occurs first. The unit's weather shield (WS19) and aluminum coil help reduce maintenance needs in harsh environments. For ROI, consider improved uptime, reduced harmonic disturbances, and lower energy losses due to efficient design when evaluating lifecycle costs against alternative solutions.
