Eaton V48M28T12EEZZ Open Core-Coil Transformer - UL
Part Number: V48M28T12EEZZ
Quick Summary
Eaton V48M28T12EEZZ is a dry-type distribution transformer delivering 480 V to 208Y/120 V for industrial facilities. In demanding environments, maintaining voltage stability, cooling efficiency, and lifecycle cost can be challenging in compact electrical rooms. UL Recognized and NEMA TP-1 compliant, with a 150 °C rise and 200 °C insulation system, provide robust safety margins. The open-core ventilated design and 112.5 kVA rating support reliable 60 Hz three-phase service, while 2 taps at +2.5% and 4 taps at -2.5% enable precise voltage regulation. This translates to improved panel performance and reduced downtime for OEMs and maintenance teams, with a clear compliance and energy-management advantage.
