Eaton N48M28B12CULS45 K-Factor transformer - UL Listed

Feature → Business Impact → Application The K-Factor nonlinear ventilated design provides enhanced tolerance to harmonic currents, reducing overheating and extending transformer life in equipment-heavy facilities. This translates to lower maintenance costs and fewer unplanned outages in manufacturing lines and data centers. In practice, the 112.5 kVA three-phase core supports scalable load growth while maintaining stable voltage regulation across 480 V primary and 208Y/120 V secondary buses, ideal for mid-to-large industrial installations and mixed-use facilities. Copper windings improve conductivity and reliability, while the electrostatic shield reduces interference, creating a cleaner power path for sensitive drives and control systems. The 80 °C rise rating sets clear thermal boundaries, informing cooling strategy and enclosure sizing for outdoor or harsh environments. Low-noise operation at 45 dB enables siting near offices or work zones without compromising compliance. The WS34 Weathershield option supports outdoors, protecting the windings from weather and dust ingress. Tap settings of 2 at +2.5% FCAN and 4 at -2.5% FCBN offer quick voltage tailoring without rewiring, saving installation time and reducing field errors. These features collectively improve energy efficiency, compliance, and total cost of ownership, while enabling faster project delivery and predictable performance in automotive, food and beverage, and process industries. The transformer’s copper coil construction and magnetics alignment help reduce stray losses, contributing to lower heat and improved plant reliability, which is a meaningful differentiator when selecting a distribution transformer for harmonics-heavy plants.
