Eaton X48M28T2216CUTHR Harmonic Transformer - DOE 2016
Part Number: X48M28T2216CUTHR
Quick Summary
The Eaton X48M28T2216CUTHR harmonic transformer mitigates harmonic distortion in three-phase industrial power systems. Industrial facilities struggle with overheating, equipment misoperation, and wasted energy caused by harmonic currents. This unit meets DOE 2016 efficiency requirements and UL Listed safety standards, with a NEMA 2 enclosure for rugged floor installations and copper windings for long-term reliability. Its floor-mount design and copper windings support straightforward installation and robust heat handling, while 2 at +2.5%, 4 at -2.5% tap settings enable precise voltage balancing for mixed 480V delta primary and 208Y/120V four-wire secondaries. In addition to compliance, it delivers energy efficiency gains and a lower total cost of ownership, making it well-suited for data centers, manufacturing lines, and process plants.

FAQs
Begin by verifying the 225 kVA rating and the 480V delta primary. Mount the unit on the floor in a protected area (NEMA 2 enclosure), connect the four-wire 208Y/120V secondary, and set the taps to +2.5% or -2.5% as needed for voltage balance. Ensure UL Listed compliance and proper thermal clearance for copper windings. Finally, commission with standard protective relays and confirm DOE 2016 efficiency performance in operation.
The transformer is three-phase with a -30° phase shift, rated at 225 kVA. Primary voltage is 480 V delta, and the secondary provides 208Y/120 V with four-wire return. It operates at 60 Hz with copper windings and an insulation rating of 220 °C, designed for robust industrial duty and stable voltage regulation under load.
Yes. The X48M28T2216CUTHR mitigates harmonic currents that can disrupt sensitive equipment and cause inefficiencies. Its DOE 2016 efficiency, UL safety, and rugged NEMA 2 enclosure support continuous operation in data centers, manufacturing cells, and process plants, delivering improved power quality, reduced energy waste, and extended asset life.
This model complies with DOE 2016 Efficient standards and is UL Listed for safety. It uses a NEMA 2 enclosure suitable for industrial floor installations and supports 480V/208V configurations.
