Eaton NT29M29S2116 Transformer for 22.5 kVA — UL Listed
Part Number: NT29M29S2116
Quick Summary
Eaton NT29M29S2116 transformer provides nonlinear power conversion for critical distribution in facilities. Engineers often struggle with voltage stability and efficiency under fluctuating loads. UL Listed and NEMA TP-1 compliant with DOE 2016 Efficient notes support regulatory and energy performance. This 22.5 kVA, single‑phase unit operates at 208 V with 60 Hz, delivering reliable voltage regulation. Taken together, the transformer reduces lifecycle costs through energy-efficient DOE-compliant design, UL/NEMA certifications, and field-ready features like taps, shielding, and rugged enclosure. For engineers and procurement teams, this translates to fewer design trades, faster installation, and predictable performance in data centers, manufacturing lines, or service enclosures. The compact footprint and 388 lb weight facilitate handling within controlled spaces and existing electrical cabinets. With aluminum windings and electrostatic shielding, EMI is minimized for sensitive equipment.

FAQs
This transformer weighs 388 lb and has a 20.36 in length, 37.59 in height, and 22.87 in width, with a Frame 818 footprint. Plan for crane-accessible placement and clearance for airflow. It’s designed for controlled spaces or enclosure mounting, and the WS11 weather shield supports outdoor or challenging indoor environments. Ensure electrical cabinet compatibility and secure mounting to prevent vibration.
The K-Factor nonlinear design targets harmonic currents by optimizing winding cooling and magnetic design, reducing additional heat under non-linear loads. Combined with ventilated construction and a 150 °C rise rating, the unit maintains temperature limits and preserves insulation integrity, lowering derating requirements and extending service life in systems with variable load profiles.
Yes. With a 22.5 kVA rating, 208 V primary and secondary, and 60 Hz operation, it supplies stable power to sensitive automation equipment and data-center distribution panels. The unit’s shielding, WS11 weathershield, and NEMA TP‑1 compliance help meet EMC and enclosure requirements, while the +2.5%/−2.5% taps accommodate voltage variations common in data-center and manufacturing environments.
The NT29M29S2116 is UL Listed and NEMA TP‑1 compliant, with DOE 2016 Efficient notes. These certifications ensure safety, reliability, and energy efficiency in regulated environments, supporting compliance during audits and facilitating seamless integration into standard industrial power systems.
Annual maintenance is limited to standard insulation and connection checks, given the robust aluminum windings and rugged enclosure. The DOE 2016 Efficient design reduces operating losses, contributing to energy savings over time. A one‑year warranty (plus Eaton’s policy 25‑000 terms) offers initial protection while helping justify TCO reductions in procurement evaluations.
