Eaton N29R47T22EE Nonlinear Ventilated Transformer - NEMA TP-1
Part Number: N29R47T22EE
Quick Summary
Eaton K-Factor nonlinear ventilated transformer provides reliable three-phase power transformation for data centers and manufacturing facilities. Maintenance and downtime worries escalate costs; this unit's robust taps and high-temperature insulation help minimize outages and stabilize critical loads. Note: Certifications are to be confirmed with the manufacturer; however, NEMA TP-1 efficiency is specified, and the unit features electrostatic shielding and WS34 weather protection to support outdoor and harsh environments. In practice, this translates to reduced energy losses, easier installation, and long-term operational resilience for power distribution across facilities. For engineers and procurement teams, this transformer combines rugged construction with predictable performance, simplifying budgeting and spare-part planning across multi-site deployments.

FAQs
Install per manufacturer guidelines, ensuring proper clearance for a 1721 lb unit with 30.68 in depth, 62.18 in height, and 31.44 in width. Use the 315A wiring connection and refer to the 918A frame specs; confirm primary 208 V and secondary 480Y/277 V wiring with your switchgear and feeders. Verify taps at +5% and -5% as needed for voltage balance.
Key ratings include 225 kVA three-phase, 60 Hz, primary 208 V, secondary 480Y/277 V, and a 150 °C rise. The device uses aluminum coil windings and supports a 315 A wiring connection, with a frame 918A for compatibility with standard installations.
Yes. The 225 kVA, 208 V to 480Y/277 V transformation supports critical loads with voltage stability. Its nonlinear K-Factor design handles harmonics, and electrostatic shielding plus WS34 weather protection enable reliable operation in both indoor and outdoor environments common to data centers and plants.
Certifications are to be confirmed with the manufacturer; catalog notes indicate NEMA TP-1 efficiency. The unit features electrostatic shielding and a WS34 weather shield, which support compliance with typical industrial power distribution standards and outdoor installation requirements.
Warranty is one year from installation or eighteen months from shipment, whichever occurs first. ROI benefits come from improved reliability, reduced downtime, energy efficiency per NEMA TP-1, and lower lifecycle costs due to rugged construction and extended service intervals.
