FAQs
This transformer supports a 480V primary and 208Y/120V secondary in a three-phase footprint. Plan for the 30.65 in L x 31.41 in W x 62.18 in H frame and a 1915 lb mass, including proper pad mounting and clearance for ventilation. Use the taps to adjust voltage as needed and ensure conduit, protective earthing, and cable sizing align with local codes and UL listings.
Key specs include 150 kVA rating, 60 Hz frequency, 80 °C rise, aluminum windings, and dual primary tap options (+2.5% / -2.5%). The unit is K-Factor nonlinear and electrostatically shielded, delivering stable secondary voltage with reduced harmonics and EMI—important for sensitive equipment and high-availability systems.
Yes. The 480V to 208Y/120V configuration, low noise level of 47 dB, and shielding make it suitable for data centers, manufacturing facilities, and critical service rooms where voltage stability, noise reduction, and EMI control are essential for uptime and safety.
This Eaton transformer is UL Listed and NEMA TP-1 compliant, offering proven safety and efficiency benchmarks for utility, regulation, and installation compliance in regulated environments.
Warranty is Eaton Selling Policy 25-000, one year from installation or eighteen months from shipment. The combination of low noise, shielded design, and robust cooling reduces maintenance intervals, enhances reliability, and can lower total cost of ownership in high-demand facilities.
