Eaton N29M28T7516CU K-Factor ventilated transformer - 60 Hz
Part Number: N29M28T7516CU
Quick Summary
The Eaton N29M28T7516CU K-Factor nonlinear ventilated transformer delivers reliable power for demanding industrial loads. Nonlinear loads often create harmonic distortion that stresses transformers and raises operating costs; this model addresses those challenges with a high K-Factor design and copper windings. It aligns with DOE 2016 efficiency requirements and features a NEMA 2 enclosure, electrostatic shield, and adjustable taps for voltage control, supporting robust performance in harsh environments. Floor or wall mounting options, along with a 75 kVA rating and 208 V primary to 208Y/120 V secondary, provide installation flexibility for control panels, motor feeders, and process equipment. In short, it combines efficiency, reliability, and practical design to reduce total cost of ownership for industrial power systems.

FAQs
This model is designed for floor or wall mounting with a NEMA 2 enclosure, supporting 208 V three‑phase primary and 208Y/120 V secondary. Consider available space for the 31.5 in L x 34.5 in W x 51 in H footprint and plan for service access, tap changer clearances, and copper winding heat dissipation. Ensure the site has adequate ventilation and routing for EMI shielding through the electrostatic shield option.
K-Factor transformers are engineered to minimize losses and overheating when exposed to harmonic currents common with nonlinear loads. The Eaton unit’s K-Factor 13 designation indicates enhanced capacity to damp harmonics, improving voltage regulation, reducing transformer stress, and extending equipment life in drives, welders, and other high‑harmonic applications.
Yes. The N29M28T7516CU is a three‑phase transformer with a 208 V primary and a 208Y/120 V secondary, making it suitable for distributing power to mixed-control equipment and loads across typical industrial plants that require a split secondary for 120 V circuits and controls.
Key compliance touchpoints include DOE 2016 efficiency (10 CFR Part 431), NEMA ST-20 sound expectations, and the NEMA 2 enclosure rating. Certifications such as CE or SIL/IP should be confirmed with the manufacturer for your region and application, as the spec sheet lists manufacturer contact for certifications.
The combination of DOE 2016 efficiency and K‑Factor harmonic resilience reduces energy waste and external cooling needs, yielding lower operating costs. Copper windings and high‑temperature insulation enhance durability, lowering maintenance downtime. The voltage taps simplify site fine‑tuning, reducing the need for additional regulators and improving overall system reliability.
