The copper-wound construction of this dry-type distribution transformer translates to lower copper losses and improved overall efficiency, supporting a measurable drop in heat generation and energy consumption across continuous operation. This directly reduces cooling requirements and operational costs in busy electrical rooms. The 112.5 kVA rating paired with 480 V primary and 208Y/120 V secondary provides a versatile solution for mid-size power upgrades, while the 2 at +2.5% and 4 at -2.5% taps give operators the ability to compensate for voltage fluctuations at the point of use, improving equipment performance and uptime. The -30° phase shift in a three-phase system helps with harmonic management and system balancing when integrated with parallel transformers or complex loads. The unit’s copper windings, frame 917, and 203X wiring connection support rugged installations in arrays and panel transfers. Weathershield WS34 and electrostatic shielding offer durable protection for outdoor or challenging environments, extending service life and reducing maintenance frequency. Compliance with UL Listed and NEMA TP-1 standards provides peace of mind for safety and performance in critical applications. With a 80 °C rise rating and 1628 lb weight, the solution is built for demanding industrial spaces while maintaining a reasonable footprint (24.67 in L × 31.44 in W × 56.17 in H). Warranty terms (one year from installation or eighteen months from shipment) add predictable support, complementing Eaton’s long-term service options.

FAQs
The transformer is a three-phase, dry-type distribution unit with a 480 V primary and 208Y/120 V secondary, designed for indoor or outdoor use with Weathershield WS34. Installation should consider a sturdy base, space for cooling, and access to taps (+2.5% and -2.5%), with wiring connection 203X. Ensure proper clearance and protective enclosures where required, and account for the unit’s 1628 lb weight during mounting and transport. Confirm UL Listed and NEMA TP-1 compliance during commissioning.
The X48M28B12CUEETHR provides a -30° phase shift in a three-phase system, aiding harmonic distribution and balance. It is rated at 112.5 kVA with copper windings and operated at 60 Hz, which helps reduce waveform distortion. The transformer’s NEMA TP-1 efficient designation and UL Listed certification reinforce safety and efficiency, contributing to lower losses and improved power factor in non-linear loading environments.
Industries with demanding power quality needs—such as data centers, manufacturing floors with non-linear loads, and hospital or facility switching environments—benefit from the X48M28B12CUEETHR. Its voltage taps, phase shift, and copper-wound efficiency support reliable operation, energy savings, and easier panel integration in complex electrical distributions.
This transformer is UL Listed and compliant with NEMA TP-1, including a designation for TP-1 efficiency. These certifications indicate adherence to established safety and energy performance standards, simplifying regulatory reviews, supplier qualification, and long-term maintenance planning in regulated industries.
The combination of NEMA TP-1 efficiency, copper windings, and 80 °C rise contributes to lower energy losses and reduced cooling loads, delivering tangible operating-cost savings. A one-year warranty (or eighteen months from shipment) helps mitigate initial risk, while ongoing support from Eaton can improve uptime and reduce maintenance interruptions in mission-critical applications.
