Eaton N48M28F45LS42 Transformer - UL Listed
Part Number: N48M28F45LS42
Quick Summary
Eaton K-Factor nonlinear ventilated transformer delivers dependable power conditioning for three-phase industrial distribution in demanding facilities. Engineers often struggle with noise, excessive heat, and space constraints when integrating transformers near drives and motors. UL Listed certification supports safety compliance and reliable operation in critical facilities. With a 480 V primary and 208Y/120 V secondary, aluminum windings, and ventilated cooling, it suits industrial power management needs. This design supports uptime, offers adjustable taps, and integrates with standard IEC/NEMA hardware for straightforward installation. Operators benefit from low sound output and compact footprint in control rooms, switchgear, and panelboards, while maintenance teams value the 25-000 warranty policy. This combination of safety, efficiency, and rugged construction translates to lower life-cycle costs and predictable performance under motor-load transients.

Eaton Specification Sheet - N48M28F45LS42
Feature: K-Factor nonlinear harmonics tolerance with an electrostatic shield reduces cumulative heating and shields sensitive upstream electronics from harmonic currents, delivering higher transformer longevity and lower maintenance costs. Business Impact: By mitigating thermal stress and insulating critical controls, uptime improves and unscheduled downtime decreases during peak drive harmonics. Application: Particularly beneficial in facilities with heavy motor drives, active front-end converters, and mixed PV/inverter loads where harmonic management is essential. Feature: Ventilated design enabling robust cooling at 60 Hz. Business Impact: Lower temperature rise translates to safer continuous operation, tighter voltage regulation, and longer insulation life. Application: Power distribution in manufacturing lines, process industries, and data-critical environments. Feature: Aluminum windings and electrostatic shielding. Business Impact: Lighter weight and improved fault protection reduce crane time and field service costs. Application: Retrofit and new builds in constrained spaces. Feature: Tap changer with taps 2 at +2.5% FCAN and 4 at -2.5% FCBN. Business Impact: Voltage optimization under varying load conditions prevents under/over-voltage events and reduces equipment stress. Application: Plants with voltage fluctuations or long feeder runs. Feature: Low sound rating 42 dB and WS39 weather shield. Business Impact: Quiet operation enables siting in adjacent spaces and outdoor enclosures; weather shield extends service life in harsh environments. Application: Control room adjacencies, outdoor substations, or switchgear installations. Feature: UL Listed certification and a standard one-year warranty (25-000). Business Impact: Compliance assurance and risk mitigation with access to Eaton support and parts during the warranty period; reduces total cost of ownership. Application: Any facility requiring certified electrical equipment with dependable vendor support.
