Copper windings and dry-type construction deliver robust durability and low operating losses, translating to improved energy efficiency and reduced heat in confined spaces, while enabling indoor or protected outdoor deployments. The business impact is a lower total cost of ownership through reduced cooling demand and longer service intervals, particularly in data centers and production lines that demand stable voltage. The application is ideal for PV curbside facilities, commercial buildings, and manufacturing floors where clean power quality is critical. Tap-changing capability provides precise voltage regulation with 2 taps at +2.5% and 4 taps at -2.5%, maintaining a stable 480 V to 208Y/120 V secondary under fluctuating loads—mitigating nuisance trips and protecting sensitive equipment. This feature supports reliable performance in variable solar and load conditions. The transformer is three-phase at 60 Hz with a -15° phase shift, aligning with typical utility and facility harmonics profiles, improving power factor, and reducing circulating currents. The device’s 30 kVA rating matches mid-sized distribution needs, enabling scalable deployments without overbuilding. Compliance features include UL Listed and NEMA TP-1 compliance, plus NEMA TP-1 efficient designation, which supports code adherence and lower standby losses. Weathershield WS38 and copper windings provide weather resistance and longevity in semi-exposed spaces, while a frame 912B and 200X wiring connection simplify mounting and terminations. The 150°C rise with a 200°C insulation system ensures a comfortable margin for short-term overloads, protecting downstream equipment and reducing failure risk. Finally, the 30 kVA dry-type transformer integrates with existing Eaton product lines and is supported by a one-year warranty (with the standard 18-month from shipment policy), delivering a solid lifecycle value and predictable maintenance planning for plant engineers.
