Eaton N48M48T12EE Transformer - K-Factor Nonlinear
Part Number: N48M48T12EE
Quick Summary
Eaton N48M48T12EE transformer delivers nonlinear K-Factor power conditioning for 3-phase 480 V distribution in industrial facilities. Many plants face voltage sags and harmonic stress that reduce equipment life and efficiency. Certifications and compliance considerations should be verified with Eaton, including CE marks and site-specific safety requirements. The 112.5 kVA rating with taps and ventilated cooling supports reliable power for demanding processes, while the 480 V primary to 480 delta secondary design aligns with standard industrial distribution schemes. This makes it a strategic choice for improving power quality, reducing downtime, and enabling scalable automation upgrades. Operators gain predictable electrical characteristics, while maintenance teams benefit from clearer specification and parts support. Overall, the N48M48T12EE helps align power infrastructure with evolving Industry 4.0 needs.

Eaton Specification Sheet - N48M48T12EE
Feature: K-Factor nonlinear design minimizes harmonic distortion in fed loads, reducing transformer overheating and downstream equipment wear. Business impact: improved power quality translates into longer motor and drive life, fewer nuisance trippings, and lower maintenance costs. Application: ideal for harmonics-rich manufacturing lines, inverter-driven conveyors, and data-center support equipment integrated into 3-phase power networks. Feature: 112.5 kVA capacity with 480 V primary and 480 delta secondary supports a wide range of plant feeders. Business impact: enables a single transformer to serve mid-size feeders, reducing footprint, wiring complexity, and total installed cost. Application: machine centers, panel boards, and sub-feed enclosures in manufacturing plants. Feature: Voltage taps at +2.5% and -2.5% enable precise regulation across voltage fluctuations. Business impact: tighter voltage control minimizes performance losses and protects sensitive equipment downstream. Application: facilities with long feeders, motor drives, or inconsistent incoming supply. Feature: Ventilated cooling delivers 150°C rise with a 200°C insulation margin. Business impact: higher thermal tolerance lowers derating, extends service life, and reduces spare parts risk. Application: high-load periods, continuous operation environments, and installations with limited cooling capacity. Feature: Clear integration with Eaton catalogs and Transformer Flex Center resources. Business impact: shorter procurement cycles, easier installation planning, and access to technical support and guidelines. Application: project teams designing electrical rooms, campuses, or automation upgrades. Feature: Compatibility with standard 3-phase 480 V distribution reduces integration risk. Business impact: streamlined onboarding for existing plants and contractors, with predictable installation steps and fewer reworks. Application: industrial automation, packaging lines, and process control systems.

FAQs
Start with a certified electrical assessment, then mount per enclosure guidelines and clearances. Connect the 480 V three-phase supply to the primary terminals and the 480 delta secondary to the load panel or distribution bus. Use the +2.5% / -2.5% taps as needed for voltage regulation, torque connection hardware to manufacturer specs, and ensure proper grounding and overcurrent protection. Refer to the Eaton datasheet and catalog for torque values and wiring diagrams.
Key specs include 112.5 kVA total rating, 3-phase configuration, 480 V primary, 480 delta secondary, voltage taps of +2.5% and -2.5%, and a thermal rating of 150°C rise with a 200°C insulation system. The transformer is ventilated for better cooling, supporting reliable operation in demanding industrial environments.
Yes. The transformer features a K-Factor nonlinear design that mitigates harmonic distortion, reducing heat buildup and extending equipment life in drives, inverters, and other nonlinear loads common in modern manufacturing and automation systems.
Certification status is provided by the manufacturer. Typical installations should confirm CE marks, safety ratings, and any site-specific IP or SIL requirements with Eaton or authorized distributors before fielding the equipment.
ROI improves through reduced downtime, better power quality, and fewer tripping events, all supported by the unit's robust cooling and high thermal margin. Maintenance benefits come from longer insulation life and clearer specifications, with access to Eaton datasheets, catalogs, and support resources to simplify servicing and part replacement.
