Eaton N48M28T30EECS Transformer - K-Factor Nonlinear
Part Number: N48M28T30EECS
Quick Summary
The Eaton N48M28T30EECS transformer delivers K-Factor nonlinear ventilation for 480V to 208Y/120V three-phase systems. Engineers often struggle with voltage drift and overheating in dense electrical panels, driving downtime and higher cooling costs. NEMA TP-1 efficient design notes ensure lower energy losses, while a 150 °C rise rating supports sustained operation in demanding environments. With a 30 kVA rating and three-phase configuration, it provides scalable support for motor drives, power distribution, and control panels in manufacturing. Taps at +2.5% and -2.5% provide fast voltage compensation, and aluminum windings plus an electrostatic copper shield improve reliability.

Eaton Specification Sheet - N48M28T30EECS
The K-Factor nonlinear ventilated design reduces harmonic heating and improves thermal management, translating to lower cabinet temperatures and longer component life in high-density switchgear environments. This directly impacts overall equipment effectiveness by enabling steadier voltage under transient loads and reducing nuisance tripping in critical lines. The 30 kVA three-phase configuration supports a broad range of mid-size machine tools, drives, and panel boards, enabling seamless integration into existing power distribution schemes without extensive rework. With primary 480 V and secondary 208Y/120 V, the unit is compatible with common industrial DC drives and AC motors, simplifying procurement and installation. The +2.5% / -2.5% taps provide rapid voltage regulation to maintain downstream equipment performance during line fluctuations, minimizing efficiency loss and improving process consistency. Aluminum windings paired with an electrostatic copper shield deliver robust electrical performance and improved insulation integrity under elevated temperatures. The WS38 weather shield extends outdoor or warehouse floor resilience, reducing weather-related degradation. NEMA TP-1 efficiency support adds a deterministic energy-saving advantage for energy-conscious facilities.
