FAQs
This transformer uses a 919X frame and weighs 3578 lb, with dimensions around 75 in tall, 44.2 in wide, and 36.23 in deep. Plan for standard electrical room clearances, proper lifting hardware, and the WS35 weather-shield option for outdoor or semi-outdoor installations. Ensure 480 V to 208Y/120 V three-phase wiring is routed through the 201X connection and that grounding complies with local codes.
Key specs include a 225 kVA rating, 60 Hz, three-phase operation, primary 480 V, secondary 208Y/120 V, water-tight phase alignment (0°), and voltage taps of +2.5% and -2.5%. Copper windings and a 150 °C rise with a 200 °C insulation system support robust performance under full load.
Yes. The unit is UL Listed and NEMA TP-1 compliant, with catalog notes highlighting NEMA TP-1 efficiency and low-noise operation. This combination simplifies regulatory approvals and ensures compatibility with standard commercial and industrial equipment.
This transformer is ideal for harmonic mitigation in PV-equipped facilities and industrial power distribution. It supports critical loads by maintaining voltage under fluctuation, reducing harmonics in 480 V to 208Y/120 V networks, and easing system commissioning in manufacturing plants and data centers.
Warranty terms follow Eaton’s policy: one year from installation or eighteen months from shipment, whichever occurs first. Routine maintenance focuses on visual inspections, cooling path cleanliness, and connection integrity. The UL/NEMA TP-1 certifications help ensure ongoing compliance and reliability for long-term ROI.
