Eaton Specification Sheet - N48M28F12EESS
The N48M28F12EESS delivers high‑capacity three‑phase power with a 112.5 kVA rating and a 480 V primary feeding a 208Y/120 V secondary, designed for 60 Hz operation. This combination ensures dependable voltage delivery to motors, drives, and consoles while enabling tighter electrical distribution within machinery rooms and switchgear assemblies. The transformer includes two taps at +2.5% and four taps at -2.5% to compensate for voltage fluctuations under varying loads, reducing equipment stress and extending the life of downstream devices. The aluminum coil construction keeps weight manageable and facilitates field servicing, while the 916A frame supports secure, vibration‑resistant mounting in demanding environments. A 115°C rise rating allows operation in hotter facilities or during peak demand periods without compromising protection.
