Eaton Specification Sheet - X48M28F45CUEESRNON
Three-phase, 60 Hz design enables scalable 480 V to 208Y/120 V distribution, reducing equipment count and simplifying panel layouts for commercial facilities. Copper windings provide superior electrical conductivity and thermal performance under harmonic load, lowering copper losses and extending transformer life in high-demand environments. Tap changes at 2 at +2.5% and 4 at -2.5% support precise voltage regulation during peak loads or transitions, improving power quality and reducing nuisance trips. Dry-type insulation with a 115 °C rise rating and electrostatically shielded windings enhance safety and reliability, while the WS39 weather shield and NEMA TP-1 compliance deliver outdoor durability and regulatory confidence in HVAC rooms or exterior enclosures. A compact footprint with 200X wiring connections simplifies field terminations and enables straightforward integration with common switchgear and PV inverters. Built for service life, it offers a practical balance of performance, safety, and maintainability for industrial power distribution.

FAQs
For safe, compliant installation, maintain proper clearances around the 22 in L, 29 in W, 39 in H footprint and accommodate its 627 lb weight with appropriate mounting and hoisting. Use 200X wiring terminations per local codes, ensure adequate ventilation, and consider the WS39 weather shield if installed outdoors. Plan for three-phase 60 Hz supply and 480 V primary with 208Y/120 V secondary wiring.
The unit employs copper windings and electrostatic shielding to minimize harmonic distortion, reducing circulating currents and heat generation. With a 0° phase shift and NEMA TP-1 efficiency considerations, it maintains power quality while enabling tighter voltage regulation across fluctuating loads, which lowers energy waste and extends equipment life in demanding plants.
Yes. The 480 V to 208Y/120 V configuration, 45 kVA rating, and tight voltage regulation make it ideal for PV systems and data centers where clean power and reliable distribution are crucial. Its rugged dry-type construction and WS39 outdoor option support outdoor rooftop or yard installations, while the +2.5%/ -2.5% taps accommodate load swings common in renewable energy and IT environments.
The X48M28F45CUEESRNON is UL Listed and complies with NEMA TP-1 efficiency requirements. A certified sound level report accompanies the catalog information, helping with acoustic requirements in sensitive facilities. These certifications simplify procurement, installation approvals, and regulatory adherence across industrial and commercial sites.
The transformer’s copper windings and robust dry-type design reduce thermal stress and maintenance needs while improving power quality, which lowers downtime and equipment wear. With a 45 kVA rating, it scales with growing loads, offering predictable operating costs and a favorable ROI as harmonic-related losses, tripping, and energy waste decline over time.
