Tap settings provide precise voltage regulation, enabling stable downstream voltage from a 480 V source and reducing nuisance tripping and equipment stress. This translates to improved uptime and longer asset life in data centers, manufacturing lines, and multi-panel distributions. Copper windings offer low resistance and high efficiency, contributing to lower I2R losses and cooler operating temperatures, which reduces maintenance and extends transformer life in continuous-process environments. The dry-type construction with UL Listing and NEMA TP-1 compliance lowers safety risk and simplifies installation in occupied or retrofit spaces, while WS39 weather shielding supports outdoor or semi-indoor use and reduces protective enclosure requirements. A -15° phase shift aids harmonic mitigation for systems with nonlinear loads, improving power factor and reducing circulating currents in intensive production facilities. With 208Y/120 V secondary, control circuits and lighting can derive stable 120 V from a common source, simplifying panel design and reducing parts count. The sturdy 915D frame and copper windings are matched to heavy-duty industrial use, and taps, insulation, and high-temperature rise rating enable robust performance in tight electrical rooms where ventilation is limited.

FAQs
This transformer is designed for 480 V three-phase service at 60 Hz, with a copper-wound dry-type configuration and a 915D frame. It includes taps at +2.5% and -2.5% to accommodate voltage fluctuations and maintain a stable 208Y/120 V secondary. Plan for proper clearance, ventilation, and Weathershield WS39 usage in outdoor or semi-indoor locations to ensure safe, code-compliant installation.
The X48M28T45CUEENEG is a 45 kVA, three-phase transformer rated for 60 Hz operation. Primary voltage is 480 V with a secondary of 208Y/120 V. It features a -15° phase shift, copper windings, a 150 °C insulation rise, and a 22 in by 29 in by 39 in footprint with a weight of about 627 lb, making it suitable for compact, demanding installations.
Yes. The unit is UL Listed and complies with NEMA TP-1 standards, including TP-1 efficiency notes. These certifications support safer operation, easier regulatory compliance, and enhanced reliability for critical loads in industrial environments.
The transformer carries Eaton’s warranty: one year from installation or eighteen months from shipment, whichever occurs first. Its dry-type design reduces maintenance needs, and copper windings along with rugged frame construction support long life under continuous duty. Regular inspection and thermal monitoring are recommended to sustain peak efficiency.
The -15° phase shift helps mitigate harmonic currents in systems with nonlinear loads, improving power factor and reducing stray currents. Copper windings offer lower resistance and better thermal performance than aluminum equivalents, delivering higher efficiency, lower losses, and more stable voltage regulation under varying load conditions.
