Eaton Specification Sheet - N29R47T12CUEE
The K-Factor nonlinear ventilated design provides superior harmonic handling, reducing overheating and extending service life in drives and non-linear loads. Business impact: improved uptime, reduced cooling energy, and lower maintenance costs. Application: data centers and manufacturing floors where non-linear loads are common. The 112.5 kVA, three-phase configuration with 208 V primary and 480Y/277 V secondary enables direct integration with common power rails, simplifying panel design and reducing the need for intermediate transformers. Business impact: faster deployment, fewer transformation stages, and lower installation footprint. Application: machine controls, packaging lines, and process automation where precise voltage control matters. Tap adjustments at +5% and -5% support site voltage variability, enabling stable operation without external regulators. Business impact: voltage stability, reduced equipment wear, and extended motor life. Application: facilities with variable line conditions. Copper windings, 150 °C rise and 200 °C insulation system deliver resilience and efficiency. Business impact: durable performance and energy efficiency, lowering life-cycle costs. Application: high-demand environments with continuous operations. Electrostatics shielding and WS19 weathershield enhance reliability in outdoor or harsh indoor spaces. Business impact: protected operation and reduced maintenance in outdoor installations. Application: outdoor substations or exposed equipment bays. Compliance with NEMA TP-1 and UL Listed ensures regulatory alignment and safer installations. Business impact: faster procurement approvals and risk mitigation. Application: OEMs and integrators pursuing compliant, certified power solutions.

FAQs
This unit weighs 1,078 lb with dimensions of 23.42 in (L) by 28.22 in (W) by 48.56 in (H) and uses a 916A frame. Plan for a solid foundation, appropriate enclosures or Weathershield WS19 for outdoor use, and adequate clearance for ventilation and maintenance access. Its copper-wound construction and robust insulation support outdoor or harsh indoor environments, while securing safe, code-compliant electrical terminations.
The N29R47T12CUEE provides 112.5 kVA, three-phase power with a 208 V primary and 480 Y/277 V secondary at 60 Hz. Taps include 1 at +5% and 2 at -5%, enabling voltage adjustments to accommodate supply variations. Copper windings and a 150 °C rise with 200 °C insulation support high-temperature operation and reliable performance under load.
Ideal for control panels, drives, and power distribution in manufacturing lines and data centers where nonlinear loads are common. The K-Factor nonlinear design helps manage harmonic currents, improving equipment longevity and reducing cooling requirements. It is well-suited for facilities using 208 V to 480Y/277 V service and needing dependable three-phase power delivery.
The N29R47T12CUEE is UL Listed and NEMA TP-1 Compliant, with NEMA TP-1 efficiency noted in catalog notes. These certifications support reliability, safety, and energy efficiency requirements for regulated industrial installations and equipment in controlled environments.
With copper windings, robust insulation, and weather protection options, maintenance needs are minimized, translating to lower lifecycle costs. The UL/NEMA certifications help reduce compliance risk, while the 1-year warranty (or 18 months from shipment) provides immediate protection against manufacturing defects, supporting faster ROI in capital projects.
