Eaton N48M28F22EES2 Transformer - 225 kVA K-Factor
Part Number: N48M28F22EES2
Quick Summary
The Eaton N48M28F22EES2 transformer delivers K‑Factor nonlinear power conditioning for industrial distribution applications. Many plants struggle with harmonic distortion and voltage swings that stress drives and controls. Common certifications for this class include CE marking and UL safety recognition; SIL ratings and IP protection depend on enclosure and installation context. With a 225 kVA rating and adjustable taps, this solution combines reliability with flexibility, supporting energy efficiency and safer equipment life in critical processes. For procurement teams, this translates to fewer outages, easier compliance reporting, and predictable budgeting for upgrades. Engineers will value its compatibility with standard 3‑phase industrial distributions and Eaton’s support resources.

Eaton Specification Sheet - N48M28F22EES2
Feature: K‑Factor nonlinear ventilated transformer design. This approach reduces harmonic currents and voltage distortion, protecting sensitive drives and controls while improving overall power quality for critical processes in manufacturing, metalworking, and packaging lines. Feature: Taps at +2.5% and -2.5% provide voltage regulation. The business impact is tighter voltage control, reducing motor stall, equipment stress, and nuisance trips across fluctuating grids; applications include panel boards, motor control centers, and critical plant feeders. Feature: 3-phase KT-13, 225 kVA rating. This configuration simplifies integration with existing 480 V/208 Y/120 V utilities and minimizes transformer bank footprint in switchgear rooms. Feature: 115°C rise rating. This capability supports hotter environments with less derating, increasing uptime in high-ambient plants such as foundries and warehouses with limited cooling. Feature: Ventilated design for robust cooling. Improved thermal performance lowers maintenance needs and extends service life in continuous operations. Feature: Documentation and resources. Access to Eaton specification sheets and the Transformer Flex Center enhances planning, approval cycles, and field installation success.

FAQs
The N48M28F22EES2 is a three‑phase transformer designed for standard industrial power distribution. It supports a 480 V primary and 208 Y/120 V secondary configuration, with taps at +2.5% and -2.5% to accommodate voltage variations. Use it in switchgear, distribution panels, and motor control centers where Eaton equipment and service support are available for integration and commissioning.
The K‑Factor nonlinear design mitigates harmonic currents and voltage distortion, protecting sensitive loads such as drives and controls. This results in improved power quality, fewer nuisance trips, longer motor life, and reduced cooling and maintenance requirements in environments with harmonic-rich loads common to modern manufacturing and processing facilities.
Yes, the N48M28F22EES2 is built for demanding industrial settings with a 115°C rise rating and a ventilated construction that supports better cooling under high ambient conditions. While enclosure protection and installation location influence exposure tolerance, the design emphasizes reliability and uptime in hot, busy plants like foundries, metal shops, and large warehouses.
Plan for a straightforward 3‑phase connection to existing 480 V feeders or switchgear, with attention to proper ventilation and clearance for airflow. The ability to adjust taps helps maintain voltage within tolerance, reducing equipment stress. Over the lifecycle, improved power quality lowers maintenance costs, minimizes downtime, and extends the life of downstream equipment, delivering measurable ROI.
