Eaton Specification Sheet - N48M28F30LS42
Feature → Business Impact → Application: The N48M28F30LS42 uses a K-13, K-Factor nonlinear design to enhance fault tolerance and thermal performance, reducing the risk of overheating under varying loads and short-circuit conditions. This translates to improved uptime and lower maintenance costs in continuous process lines and industrial controls. The three-phase 30 kVA rating with a 480 V primary and 208Y/120 V secondary supports scalable power distribution for motor drives, panelboards, and MCCs, enabling engineers to consolidate transformers within standard switchgear footprints while meeting voltage regulation requirements. With taps at 2 positions (+2.5% FCAN) and 4 positions (-2.5% FCBN), precise voltage adjustments are possible to compensate for line drop in long runs, improving equipment performance and control accuracy. Aluminum windings offer lightweight durability and corrosion resistance, reducing shipping and handling costs while improving thermal response. The electrostatic shield minimizes EMI, enhancing signal integrity for sensitive control systems in robotics and automation cells. A frame design of 912B supports straightforward mounting in compact enclosures, aiding retrofits and new installations alike. The Weathershield WS38 option expands outdoor or harsh-environment applications, protecting windings from moisture and dust ingress. Low sound 42 dB notes ensure quieter operation in noise-sensitive facilities such as data centers, laboratories, and production lines. UL Listed certification provides a clear compliance signal during procurement, while the 1-year warranty (or 18 months from shipment) offers warranty coverage and supplier confidence. These features collectively deliver measurable outcomes: improved energy efficiency, predictable voltage regulation, faster installation, and a lower total cost of ownership for industrial power distribution projects.

FAQs
For installation, ensure adequate clearance around the 912B frame and the Weathershield option if used in outdoor or dusty environments. Mounting should accommodate the 315 lb weight with proper hardware, and consider the 16.5 in depth, 23 in width, and 30 in height footprint. Verify primary 480 V and secondary 208Y/120 V connections, and utilize the 2 at +2.5% and 4 at -2.5% taps to optimize voltage at the load end.
Key specs include a 30 kVA rating, three-phase configuration, 60 Hz operation, 480 V primary, 208Y/120 V secondary, aluminum windings, electrostatic shield, and 115°C temperature rise. The unit is UL Listed and features a low-sound rating of 42 dB, making it suitable for noise-sensitive environments. Taps provide voltage adjustment to minimize regulation concerns.
Yes. The transformer’s three-phase 30 kVA rating, precise tap options, and shielded design help maintain stable voltages for critical loads in data centers and manufacturing lines.
