Eaton Specification Sheet - N48M28F12CULS47
K-Factor nonlinear design with copper windings and electrostatic shielding delivers enhanced harmonic mitigation and improved thermal performance, safeguarding downstream equipment and reducing maintenance. This translates to reliable operation in automation panels, motor drives, and process lines where harmonic content is high. Ventilated construction with WS34 weather shield and a 115 °C rise supports superior cooling and lower acoustic emissions, enabling operation in hot, industrial environments with minimal downtime. This is ideal for manufacturing floors, distribution centers, and outdoor enclosures where heat and noise are common concerns. Voltage regulation with taps at 2 at +2.5% FCAN and 4 at -2.5% FCBN allows precise voltage adjustment, keeping secondary voltage within tolerance despite input fluctuations. This reduces equipment stress and maintenance, benefiting sensitive controls in dynamic power networks and automated lines. 112.5 kVA three-phase capacity at 60 Hz with a 480 V primary and 208Y/120 V secondary delivers wide distribution capability in a compact footprint. This lowers cabinet count and simplifies wiring in control rooms and plant-wide power distribution schemes. Copper windings, electrostatic shield, and frame 918A contribute to higher efficiency and EMI protection, improving reliability for drives, sensors, and communication equipment located near the transformer. The WS34 weather shield further enhances durability in exposed or harsh environments.

FAQs
Plan for the 1458 lb unit with the 918A frame, ensuring solid foundation, adequate ventilation, and clearance for service. Consider the WS34 weather shield for outdoor or harsh environments and apply the 60 Hz operating requirement. Verify copper windings and electrostatic shield installation to maximize EMI protection and thermal performance in your control room or MCC.
The K-Factor nonlinear design targets harmonics present in motor drives and other nonlinear loads, reducing overheating and voltage distortion. This improves downstream equipment life and maintains voltage quality across critical processes. In practice, you’ll see better uptime, fewer nuisance trips, and safer operation for automation equipment in production lines.
Yes, the transformer is UL Listed, ensuring compliance with safety and performance standards. It carries Eaton’s warranty policy of one year from date of installation or eighteen months from shipment, whichever occurs first, providing protection during initial deployment and early operation phases.
The unit is rated at 112.5 kVA with a 480 V primary and 208Y/120 V secondary, configured for three-phase operation at 60 Hz. This combination supports robust power distribution to multiple circuits from a single transformer, simplifying panel design and reducing wiring complexity.
WS34 weathershield compatibility and the 918A frame are designed for durable mounting in controlled and exposed environments.
