Eaton N29M28T25EE Transformer - UL Listed, NEMA TP-1
Part Number: N29M28T25EE
Quick Summary
The Eaton N29M28T25EE transformer delivers reliable three-phase power conditioning for data centers, industrial controls, and heavy equipment. Nonlinear loads often distort voltage and shorten equipment life; this transformer mitigates those effects with a K-Factor nonlinear design and ventilated cooling. UL Listed and NEMA TP-1 compliant, the unit also notes NEMA TP-1 efficiency, aligning with industry standards for power distribution and controls. With a 25 kVA rating, 208 V primary, 208Y/120 V secondary, 60 Hz operation, and +2.5% / -2.5% taps, it's ready for flexible installation in modern facilities. Operators benefit from reinforced EMI protection through electrostatic shielding and robust Weathershield WS38 enclosure for outdoor or harsh indoor environments.
