Eaton Specification Sheet - N48M28T12CULS45
Feature: K-Factor nonlinear design helps manage harmonic currents and uneven load profiles. Business Impact: Reduces EMI and thermal stress on downstream equipment, boosting reliability and energy efficiency. Application: Ideal for facilities with non-linear loads and variable demand, such as motors, drives, and power conversion systems. Feature: Three-phase 112.5 kVA rating with 480 V primary and 208Y/120 V secondary. Business Impact: Supports scalable distribution plus flexible panel feeding while maintaining precise voltage levels. Application: Suitable for mid-size industrial plants and critical control rooms needing stable secondary voltages. Feature: Copper windings with electrostatic shield. Business Impact: Lower resistance losses and improved EMI protection translate to better efficiency and equipment protection. Application: Essential where sensitive electronics or automation controllers are close to the transformer. Feature: Tap changes of 2 at +2.5% FCAN and 4 at -2.5% FCBN. Business Impact: Enables on-site voltage regulation to accommodate supply fluctuations, preserving performance. Application: Helpful in installations with long feeders or voltage drop concerns. Feature: Frame 917 with WS34 Weathershield. Business Impact: Durable, weather-resistant enclosure supports outdoor or harsh-environment installations with reduced maintenance. Application: Outdoor substations or building spaces exposed to ambient conditions. Feature: Low sound level of 45 dB (catalog note). Business Impact: Quieter operation minimizes noise-related disturbances in plant floors and control rooms. Application: Plant rooms with noise constraints or shared spaces.

FAQs
This transformer is designed for industrial three-phase power distribution with a 480 V primary and 208Y/120 V secondary. It supports voltage regulation via taps (+2.5% and -2.5%), features copper windings and an electrostatic shield for EMI protection, and uses the WS34 weather shield for rugged outdoor or harsh-environment installations.
Key ratings include a 112.5 kVA power rating, 60 Hz frequency, 480 V primary, 208Y/120 V secondary, copper windings, and a 150 °C rise. It is UL Listed and designed as a ventilated, three-phase transformer with a low-noise profile of 45 dB, supporting reliable operation in demanding facilities.
Yes. The K-Factor nonlinear design helps manage harmonic currents and reduce EMI stress on downstream equipment, improving overall system efficiency and extending component life in facilities with variable loads, drives, and non-linear power conversion.
The model is UL Listed, signaling compliance with recognized safety standards for electrical equipment. This certification supports safe procurement and commissioning in industrial facilities and reduces risk during inspections and audits.
The combination of a 150 °C rise rating, electrostatic shielding, and low-noise operation lowers cooling and EMI-related failures, reducing maintenance frequency. A robust design with voltage taps aids consistent performance under varying loads, contributing to improved uptime and lower total cost of ownership.
