Eaton X25M31T1516NON Harmonic Transformer - DOE2016
Part Number: X25M31T1516NON
Quick Summary
Eaton Harmonic mitigating transformer reduces harmonic distortion in three-phase power systems used in manufacturing and automation. It delivers clean, stable voltage to sensitive equipment, improving uptime and extending equipment life. Uncorrected harmonics drive higher losses, heat, and nuisance trips, eroding efficiency and increasing maintenance costs. Key standards underpinning its design include DOE2016 Efficient compliance, a NEMA 2 enclosure for indoor environments, and a 60 Hz rating with NEMA ST-20 sound performance. With this transformer, engineers gain a compact, compliant solution that integrates smoothly into panel boards and automation racks while supporting energy-reduction targets and reliable operation.

FAQs
Consider floor mounting in a protected indoor space, 60 Hz three-phase input, 220 V primary, and 220Y/127 V secondary. Ensure wiring uses 211X connections, and plan for the +2.5% / -2.5% tap adjustments to handle voltage variation. The unit uses a NEMA 2 enclosure for indoor protection and DOE2016 efficiency.
Expect reduced harmonic distortion and lower electrical losses due to the DT-3 energy-efficient design, contributing to cooler operation and improved overall efficiency. The 15 kVA rating supports moderate to large panel loads, with 0° phase shift maintaining compatible power delivery for three-phase systems in automation environments.
Yes. With three-phase 60 Hz operation, 15 kVA capacity, and 220 V primary feeding a 220Y/127 V secondary, the X25M31T1516NON integrates well into automation panels and factory electrical rooms. Indoor NEMA 2 protection and floor mounting support reliable installation in typical manufacturing environments.
The unit complies with DOE2016 Efficient standards for energy performance and features a NEMA ST-20 sound rating. The enclosure is NEMA 2 for indoor protection, and the catalog notes reference 10 CFR Part 431 (2016) Efficient guidelines, aligning with energy-efficiency and safety requirements.
The combination of DOE2016 efficiency and harmonic mitigation reduces energy losses and heat, contributing to lower operating costs and less maintenance downtime. Its electrostatic shield option and robust aluminum windings further reduce EMI and wear, supporting longer service intervals and a favorable ROI in automated facilities.
