Eaton Specification Sheet - X48M28F75TCUEEPOS
Feature: Tap size with two +2.5% FCAN taps and four -2.5% FCBN taps enables precise voltage regulation under fluctuating line conditions. Impact: maintains secondary voltage within tight limits, reducing equipment stress, nuisance tripping, and copper losses due to misregulated loads. Application: data centers, machine tools, and mixed-load facilities where demand varies during shifts. Feature: Copper windings and a 115 °C rise rating deliver high conductivity and thermal margin. Impact: lower I2R losses, improved cooling flexibility, and sustained performance in hot environments. Application: continuous operation in equipment rooms and outdoor enclosures when used with WS19 weather shield. Feature: Dry-type distribution transformer construction reduces oil fire risk and simplifies indoor installations. Impact: safer facility integration, lower maintenance requirements, and easier adherence to safety codes. Application: electronics labs, manufacturing floors, and confined spaces. Feature: Three-phase, 60 Hz operation with 75 kVA rating, 480 V primary and 208Y/120 V secondary, plus 15° phase shift. Impact: predictable response to harmonics and balanced loading, enabling tighter controls and improved energy efficiency. Application: large motor drives, pumps, and control panels in industrial settings. Feature: Weathershield WS19 option and electrostatic shielding enhance outdoor viability and EMI management. Impact: expands installation options to outdoor substations or exterior equipment rooms while protecting sensitive electronics. Application: mixed indoor/outdoor facilities and retrofit projects.

FAQs
To install, de-energize the system, mount the unit in a suitable enclosure or on a solid base with adequate clearance, and connect the primary to 480 V using the 200X wiring configuration. Wire the secondary to 208Y/120 V, verify 60 Hz operation, observe the 3-phase rotation, and set taps to maintain desired voltage. Confirm UL and NEMA TP-1 considerations during commissioning.
Key specs include a 75 kVA rating, 60 Hz frequency, three-phase configuration, primary 480 V, secondary 208Y/120 V, 15° phase shift, copper windings, and a 115 °C rise. It offers taps at +2.5% and -2.5%, is UL Listed, and supports NEMA TP-1 compliance and efficiency, with a 75 kVA capacity suitable for medium-duty industrial loads.
Yes. Its harmonic mitigating design, tight voltage regulation, and copper windings are well-suited for data centers, machine shops, and manufacturing lines with non-linear loads. The dry-type construction simplifies indoor installation, while optional WS19 weather shield enables outdoor use in harsh environments, providing reliable power quality across mixed-load scenarios.
The X48M28F75TCUEEPOS is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficiency noted in catalog notes. These certifications reflect safety, reliability, and energy-performance expectations for commercial and industrial distributions, helping you meet regulatory requirements and internal safety programs.
The transformer comes with a one-year warranty from installation or 18 months from shipment, whichever occurs first. With copper windings and robust thermal design, maintenance needs are typically low, reducing downtime.
