Eaton X29M47T75CU16NON Harmonic Transformer DOE 2016 Efficient
Part Number: X29M47T75CU16NON
Quick Summary
Eaton Harmonic mitigating transformer delivers clean power conditioning for data centers and manufacturing facilities. Harmful harmonic currents can cause overheating, nuisance trips, and reduced equipment life, complicating maintenance budgets. This model carries DOE 2016 efficiency compliance, UL Listed certification, and a NEMA ST-20 enclosure to support industrial installs. Designed for floor-mounted panels in electrical rooms, it helps facilities meet energy codes while reducing losses. By delivering stable voltage with zero phase shift and copper windings, it supports higher system reliability and longer asset life, while enabling straightforward replacement in existing low-voltage distributions. The result is improved power quality, reduced downtime, and predictable total cost of ownership with Eaton.

Eaton Specification Sheet - X29M47T75CU16NON
The 75 kVA three-phase transformer delivers robust harmonic mitigation with zero degree phase shift, improving power quality and reducing thermal stress on sensitive equipment, which translates to lower maintenance costs and longer mean time between failure in data centers and automation facilities. This configuration supports 208 V delta primary and 480Y/277 V four-wire secondary, enabling seamless integration with modern panel boards and switchgear while supporting essential voltage flexibility for automation lines. A copper-windings design and 220 °C insulation heighten reliability in demanding environments, while the NEMA 2 enclosure and floor mounting simplify installation in standard electrical rooms, reducing project lead times. Tap changes at two points (+2.5%) and four points (-2.5%) allow precise voltage tuning to minimize line losses and improve feeder performance. DOE 2016 efficiency, UL Listing, and 10 CFR Part 431 compliance reinforce regulatory alignment and long-term energy savings. The compact footprint (24 in L x 43 in H x 30.5 in W) fits typical plant layouts, while the 75 kVA rating meets mid-range critical load needs. The unit’s sound level conforms to NEMA ST-20 expectations, ensuring suitability for moderately quiet environments. Industry-specific insights indicate that harmonic mitigating transformers like this are especially beneficial in environments with nonlinear loads from drives and power supplies, helping facilities avoid oversized replacements and achieve faster ROI.

FAQs
The transformer is designed for floor mounting in indoor electrical rooms and uses copper windings with a three-phase 75 kVA rating. It features a 208 V delta primary and a 480Y/277 V four-wire secondary, with taps at +2.5% and -2.5%. Dimensionally, it fits standard footprints (approximately 24 in L x 43 in H x 30.5 in W) for straightforward panel integration and service access.
A 0° phase shift minimizes phase displacement between input and output, reducing harmonic distortion and improving voltage regulation under nonlinear loads. This enhances system efficiency, lowers circulating currents, and helps protect sensitive equipment, contributing to energy savings aligned with DOE 2016 efficiency targets while supporting reliable operation in mixed-standard power systems.
Yes. With a 75 kVA rating, three-phase design, 208 V delta to 480Y/277 V four-wire outputs, and a NEMA 2 enclosure, it is well-suited for data centers, automation panels, and manufacturing facilities. The unit’s floor-mount footprint, UL listing, and ST-20 sound compliance simplify integration into existing electrical rooms while ensuring power quality and regulator-ready performance.
The X29M47T75CU16NON is UL Listed and DOE 2016 Efficient, with compliance to 10 CFR Part 431 (2016) Efficient standards. It also conforms to NEMA ST-20 for enclosure and sound expectations. These certifications support regulatory alignment, energy-efficiency incentives, and safe operation in industrial environments.
The warranty follows Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever comes first. ROI arises from improved power quality, reduced downtime, and energy savings due to DOE 2016 efficiency and reduced losses in harmonic-rich loads, combined with longer asset life and lower maintenance costs in automation and data-center applications.
