Eaton N48M28F45CU Nonlinear Ventilated Transformer - UL Listed

Feature → Business Impact → ApplicationThe K-Factor nonlinear design reduces heat generated by harmonic currents, improving system efficiency and extending transformer life in facilities with nonlinear loads such as drives and uninterruptible power supplies. This directly lowers cooling costs and maintenance intervals in manufacturing lines and data centers, while enabling smoother voltage regulation across critical equipment. The ventilated construction combined with copper windings enhances heat dissipation, supporting reliable 60 Hz operation and stable performance in medium to large distribution panels.Electrostatic shielding and the WS39 weather shield provide EMI containment and weather resistance, reducing interference with nearby controls and enabling outdoor or rugged indoor installations in industrial plants, warehouse environments, and process lines where harsh conditions are common. These features simplify compliance with safety and reliability expectations while minimizing protective enclosure requirements and installation complexity.With a 45 kVA rating, three-phase configuration, 480 V primary, and 208Y/120 V secondary, the N48M28F45CU reduces transformer counts in centralized power distribution schemes and improves voltage stability for sensitive motors and controls. The built-in taps (2 at +2.5% FCAN, 4 at -2.5% FCBN) support precise voltage adjustments without multiple upstream transformers, streamlining commissioning and reducing long-term operating costs.The 915D frame, 22 in depth, 29 in width, and 39 in height, along with a 605 lb weight, define a rugged, service-friendly footprint that installation teams can accommodate in standard electrical rooms. Copper windings and a robust UL Listed design translate into lower risk during maintenance, easier part sourcing, and predictable performance under peak loading and fault conditions.
