Eaton Specification Sheet - X48M28B75CUEENONLS47
Feature → Business Impact → Application: Harmonic mitigation design with precise taps (+2.5% / -2.5%) reduces harmonic distortion, improves current balance, and lowers energy waste, delivering measurable efficiency gains in mixed-load environments. Application: Data centers, machine shops, and manufacturing lines with nonlinear equipment benefit from improved power quality and reliability. Feature → Business Impact → Application: Copper windings and 80°C rise enable durable performance and faster heat dissipation, boosting equipment longevity and reducing cooling loads in hot environments. Application: Heavy-duty industrial panels and outdoor installations where ambient temperatures challenge transformer longevity. Feature → Business Impact → Application: Three-phase 60 Hz operation with 75 kVA rating ensures scalable power conditioning for mid-size facilities, enabling seamless integration with existing switchgear and bus ducts. Application: Commercial and light- to mid-size industrial plants seeking predictable voltage regulation and minimal voltage drop. Feature → Business Impact → Application: Low sound 47 dB and compact footprint (916A frame) simplify installation in noise-sensitive areas and space-constrained equipment rooms. Application: Hospitals, data centers, and clean manufacturing floors requiring quiet operation. Feature → Business Impact → Application: Weathershield WS19 option and electrostatic shielding improve outdoor durability and EMI control, extending life in exterior installations. Application: Outdoor substations, external switchgear enclosures, and partially protected outdoor battery rooms. These features collectively support compliance, reduce downtime, and improve return on investment through reduced energy usage, maintenance, and early fault detection.

FAQs
Install as a dry-type distribution transformer in a ventilated area or protected enclosure (WS19 option for outdoor use). Ensure adequate clearance for the 23.42 in depth, 28.22 in width, and 48.56 in height, with proper mounting on a rigid base. Use the 200X wiring connection and plan for the 75 kVA load at 60 Hz, including the 2 at +2.5% / 4 at -2.5% taps for voltage balance.
Primary voltage is 480 V, secondary is 208Y/120 V, three-phase, at 60 Hz. The unit is rated for 75 kVA with an 80 °C rise, copper windings, frame 916A, and a 0° phase shift. It also features NEMA TP-1 compliance and UL Listing with low sound at 47 dB.
Yes. The harmonic mitigating design reduces harmonic distortion from nonlinear loads like drives and UPS, improving power quality, reducing cooling requirements, and lowering the risk of false trips. Its copper windings and precise tap settings help maintain voltage stability and reliability in data centers and manufacturing environments.
The unit is UL Listed and NEMA TP-1 compliant, with noted NEMA TP-1 efficiency in catalog notes. It also features electrostatic shielding and an available WS19 weather shield for outdoor installations, supporting compliance and reliability in diverse environments.
Warranty follows Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This supports ongoing support, with access to Eaton documentation and specification sheets for maintenance planning and long-term ROI.
