FAQs
Plan for a dry-type transformer installation with the 919X frame footprint and 201X wiring. Expect dimensions of 36.23 in length, 44.2 in width, and 75 in height, plus a weight around 3488 lb. Ensure proper ventilation, clearance for connections, and Weathershield WS35 protection for outdoor or demanding indoor environments. The unit supports straightforward mounting in standard distribution spaces.
Yes. The X48M28F22CUEENONS2P is UL Listed and NEMA TP-1 compliant, delivering assurance for safety, efficiency, and reliability in industrial settings. The catalog notes also reference 80kA per phase SPD on the secondary with an indicator light, supporting protection against transient events and aiding compliance with utility and code requirements.
Key ratings include a 225 kVA rating, 480 V primary, and 208Y/120 V secondary at 60 Hz with a 0° phase shift. Tap settings are 2 taps at +2.5% and 4 taps at -2.5%, enabling voltage regulation to accommodate feeder losses and load swings. This combination supports stable performance across typical facility loads.
Harmonic mitigation reduces distortion caused by non-linear loads, improving power quality and decreasing overheating and nuisance trips. The transformer’s copper windings and electrostatic shielding help maintain clean voltage and current waveforms, enabling safer PV integration and more reliable operation of sensitive equipment in three-phase distribution networks. This can translate to longer equipment life and lower maintenance costs.
Maximize ROI by leveraging the dry-type design for easier cooling and maintenance, the WS35 protection, and the 919X frame fit with 201X wiring. The 225 kVA rating supports load growth without repeated replacement, while UL/NEMA TP-1 compliance reduces regulatory risk. The 1-year warranty (18 months from shipment) provides vendor support while minimizing long-term ownership costs.
