Eaton N48D28T49AFCUEELS47 Nonlinear Transformer - 150 kVA
Part Number: N48D28T49AFCUEELS47
Quick Summary
Eaton K-Factor nonlinear ventilated transformer is designed for reliable three-phase power distribution in industrial facilities. Operators often contend with humidity, fungus growth, and thermal hotspots that drive unexpected outages and maintenance costs. This unit aligns with critical requirements in industrial environments—CE compliance for European markets, IP protection considerations, and SIL safety considerations—though exact listings should be confirmed with Eaton. With copper windings, 480 V primary and 208Y/120 V secondary, and adjustable taps, it supports scalable, compliant power delivery for varying loads. Designed for 150 kVA service, it helps protect sensitive equipment and drives uptime. The combination of robustness, efficient operation, and a one-year warranty translates into lower lifecycle costs and predictable performance.

Copper windings deliver low resistance and improved efficiency, reducing I2R losses and cooling requirements for steady uptime in continuous operation. Feature → Business Impact → Application: Copper windings minimize energy losses, lowering operating costs in high-load installations and improving service life for critical drives and PLCs in manufacturing lines. Application: general purpose power distribution with tight efficiency targets. Tap changes: 2 at +2.5% and 2 at -2.5% enable voltage regulation under fluctuating loads, reducing voltage-related equipment stress and extending motor life. Application: facilities with variable input conditions or long feeders. 150 kVA rating with 60 Hz operation and 480 V primary/208Y/120 V secondary supports standard US industrial power rails, enabling straightforward retrofits and new builds. Application: plant modernization projects or expansion baselines. Fungus-proof construction and electrostatic shielding enhance reliability in humid or outdoor environments, while WS34 weather protection ensures enclosure integrity. Application: outdoor substations, coastal facilities, or wash-down zones. NEMA TP-1 efficient design and low sound output (47 dB) contribute to quieter, more energy-efficient installations. Application: noise-sensitive installations near workspaces. Frame 918A and copper coil construction offer robust mechanical compatibility with common electrical rooms, supporting easier installation and serviceability. Warranty coverage adds financial protection and supplier support for ongoing maintenance planning. Application: procurement and long-term asset management with predictable ROI.

FAQs
The unit is a three-phase transformer with a 480 V primary and 208Y/120 V secondary designed for industrial facilities. Consider mounting in a suitable enclosure, ensure space for the 918A frame, plan for copper windings and 447A wiring connections, and verify mounting clearances as per local codes. Confirm WS34 weather protection if installed outdoors and factor in the 60 Hz electrical environment.
The dual-set taps allow small adjustments to the secondary voltage under fluctuating input or load conditions, helping maintain steady downstream voltage and protecting sensitive equipment from over- or under-voltage events. This reduces motor wear, improves control stability for drives and PLCs, and lowers maintenance needs in variable supply environments.
Yes. The product features fungus-proof construction and electrostatic shielding, designed to withstand humidity and EMI considerations typical of humid plants or outdoor locations. While catalog notes reference NEMA TP-1 efficiency and related design aspects, confirm final certification exposure with Eaton for your specific regional requirements.
Certifications are listed as Contact Manufacturer, so you should confirm CE, IP ratings, SIL safety considerations, and any local electrical compliance requirements with Eaton before order placement. This ensures the transformer meets regional safety, environmental, and performance standards for your application.
Copper windings and robust construction reduce energy losses and thermal stress, contributing to lower operating costs and longer asset life. The unit ships with a one-year warranty (or 18 months from shipment), supports scalable deployment with taps for voltage regulation, and provides predictable downtime reduction, translating into a favorable total cost of ownership for steady-state and peak-demand applications.
