Eaton N48M47F49A Ventilated Transformer - UL Listed
Part Number: N48M47F49A
Quick Summary
The N48M47F49A K-Factor nonlinear ventilated transformer powers critical distribution in industrial facilities. Engineers frequently contend with overheating and voltage stability issues in compact switchgear, risking downtime. UL Listed safety certification supports field deployment, while K-13 design and electrostatic shielding enhance reliability. This solution also aligns with maintenance-friendly service models and scalable power distribution for growing facilities. By supporting a 150 kVA rating at 60 Hz with adjustable taps, it adapts to load swings without sacrificing efficiency. The aluminum windings and electrostatic shield reduce stray losses and insulation wear in harsh industrial environments. Frame 917 with WS34 weathershield improves outdoor or rugged installations, while 480 V to 480Y/277 V outputs support common panel setups.

FAQs
Plan for the 24.67 in depth, 56.17 in height, and 31.44 in width footprint with a 1258 lb weight. Mount on a stable base compatible with Frame 917, provide adequate clearance for ventilation, and specify WS34 weather shield if outdoor or rugged indoor use. Ensure 480 V primary and 480Y/277 V secondary connections are correctly wired, with taps set per +2.5% and -2.5% ratings. The unit is UL Listed, which supports field deployment under standard safety practices.
The transformer delivers a 150 kVA three-phase rating at 60 Hz with a 480 V primary and a 480Y/277 V secondary, matching common industrial and data-center distribution schemes. Aluminum windings and an electrostatic shield improve thermal performance and insulation longevity, while the WS34 option supports outdoor installation. Tap adjustments enhance voltage control under varying supply conditions, ensuring stable panel voltages across fluctuating loads.
K-Factor nonlinear design, specifically K-13, minimizes heat caused by harmonic currents and reduces additional insulation stress. This leads to lower cooling requirements, longer component life, and reduced risk of thermal overstress in machines with variable drives and power electronics. For facilities with non-linear loads, the result is improved reliability and longer service intervals between maintenance cycles.
The N48M47F49A is UL Listed, indicating compliance with recognized safety standards for electrical equipment. This certification supports field deployment in regulated facilities and can simplify procurement and commissioning. While other certifications aren’t listed in the data, ensure installation follows local electrical codes and Eaton’s warranty terms for best results.
With a robust K-13 design, electrostatic shielding, and a weather-shielded frame option, the unit is built for long service life in demanding environments. The warranty offers one year from installation or 18 months from shipment. ROI benefits come from reduced downtime, improved voltage stability, and lower cooling energy needs due to effective thermal management and durable construction.
