Eaton N29R47T4916 K-Factor ventilated transformer UL
Part Number: N29R47T4916
Quick Summary
Eaton N29R47T4916 K-Factor nonlinear ventilated transformer is engineered for robust power distribution in industrial facilities. In demanding environments, engineers contend with heat buildup, energy losses, and regulatory complexity that can erode uptime and increase operating costs. This product carries UL Listed status, and aligns with DOE 2016 Efficient and 10 CFR Part 431 efficiency requirements to help you meet modern standards. By pairing a rugged NEMA 2 enclosure and FR944 frame with aluminum windings and a floor-or-wall mounting footprint, Eaton delivers reliable performance. The result is lower lifecycle costs, improved heat management, and easier compliance for new installations or retrofits, while maintaining compatibility with common low-voltage dry-type systems.

FAQs
The N29R47T4916 uses a floor or wall mounting option in a NEMA 2 enclosure. It is designed for indoor environments and pairs with WS61 Weathershield protection. For retrofits, ensure mounting clearance and accessible wiring with the E0269A connection point, and verify alignment with existing support structures to prevent vibration and ensure serviceability.
Key specs include a 150 kVA rating, three-phase operation at 60 Hz, primary 208 V, and secondary 480Y/277 V. Aluminum windings and a K-Factor 13 design help mitigate harmonic heating, improving reliability under nonlinear loads. The voltage-tap allows +5%/-5% adjustments, supporting voltage regulation in fluctuating supply conditions.
Yes. With a 150 kVA rating, 208 V to 480Y/277 V output, and a robust FR944 frame, the unit supports critical power distribution for data centers and manufacturing lines. Its energy-efficient DOE 2016 profile and UL listing provide reliability and regulatory confidence, while the electrostatic shield helps minimize EMI between adjacent equipment.
The N29R47T4916 is UL Listed and conforms to DOE 2016 efficiency requirements as well as 10 CFR Part 431 (2016 Efficient). These certifications ensure regulatory compliance, reduced energy losses, and suitability for modern building codes and procurement standards in industrial facilities.
Expect standard maintenance for dry-type transformers: regular inspection of winding insulation, enclosure integrity, and cooling pathways. The K-Factor design and DOE efficiency contribute to lower operating losses, improving ROI over time. Warranty terms include Eaton’s policy, with coverage extending one year from installation or eighteen months from shipment, whichever comes first.
