Eaton Specification Sheet - N48M28F50EE
KT-13 nonlinear K-Factor design helps balance harmonic currents and limit transformer overheating, improving reliability for variable-speed drives and high-density loads. The business impact includes reduced voltage distortion, lower cooling energy, and fewer maintenance outages, which translates into predictable uptime and lower total cost of ownership. Application-wise, the N48M28F50EE shines in data centers, automated manufacturing cells, and distribution panels that generate harmonic-rich loads while demanding robust protection. Voltage flexibility supports easier field commissioning. With a 480 V primary and 208Y/120 V secondary, plus taps at +2.5% and -2.5% (2 and 4 positions respectively), site engineers can tune voltage to match feeder conditions without swapping windings. This reduces nuisance tripping, improves regulation for sensitive equipment, and simplifies cross-application use across multiple facilities. Rugged construction stands up to harsh environments. Aluminum windings paired with the 914D frame deliver solid thermal performance and corrosion resistance, while the WS39 weather shield enables outdoor or semi-enclosed installations. Electrostatic shielding adds EMI protection, helping maintain clean control signals near motor drives and switchgear, especially in open-panel installations. Compliance, efficiency, and serviceability drive ongoing value. UL Listed and NEMA TP-1 compliant, the transformer is designed for safe operation in industrial settings. The 'NEMA TP-1 efficient' catalog note signals improved cooling and energy use, delivering measurable savings over time in facilities with continuous or high-duty cycles. Installation and maintenance advantages support fast deployment. The unit’s 22 inch depth, 29 inch width, 39 inch height, and 554 lb weight are compatible with standard mounting footprints, while the aluminum coil and modular accessories ease replacement and service. Eaton provides installation resources and training content to streamline commissioning and prevent unnecessary downtime.

FAQs
Plan for a footprint of 22 in L x 29 in W x 39 in H with a weight around 554 lb. Ensure suitable mounting on rigid bases or racks, provide adequate clearance for ventilation, and confirm surface protection for outdoor or semi-outdoor use with WS39 weather shielding as required.
KT-13 denotes a nonlinear K-Factor design that limits harmonic heating and voltage distortion. This reduces up-stream stress, extends equipment life, and helps maintain power quality for drives, controllers, and reactors in facilities with high non-linear loads.
Yes. It provides a 480 V primary and a 208Y/120 V secondary with taps at +2.5% and -2.5% to fine-tune voltages on-site. It is a three-phase, 60 Hz design suitable for mixed-load environments and easier integration into existing distribution schemes.
