Eaton Specification Sheet - X48M28T4916NON
Harmonic mitigation reduces distortions at the source, improving power quality and reducing heat in ancillary equipment. This translates to lower cooling costs, longer service life for motors and drives, and easier regulatory compliance for sensitive loads. In manufacturing lines, three-phase 480 V supply with 208Y/120 V secondary delivers stable voltages for PLCs, drives, and control panels. Tap settings provide voltage regulation under changing load. With two taps at +2.5% and four taps at -2.5%, you can compensate for voltage drop and maintain a tight secondary voltage, reducing nuisance trips and process variability. This capability is particularly valuable in plants with diverse loads, startup surges, or long feeders. Rugged construction and installation advantages streamline deployment. The unit uses aluminum windings, 220 °C insulation, and a 150 °C rise rating for reliability in harsh environments. A NEMA 2 enclosure on a floor-mounted FR943 frame matches indoor spaces, and the 31.5 in depth by 34.5 in width footprint simplifies planning. Compliance and lifecycle value are built in. DOE 2016 efficiency, UL listing, and 10 CFR Part 431 notes help with regulatory alignment while delivering measurable energy savings. The compact 150 kVA unit weighs about 1262 lb and supports straightforward integration with existing 480 V / 208Y/120 V distributions. Warranty and service support reinforce ROI. Eaton’s policy covers one year from installation or eighteen months from shipment, with access to replacement parts and product documentation for ongoing maintenance and uptime.

FAQs
Plan for floor mounting in a dry indoor space with adequate clearance for the unit’s footprint and weight. The NEMA 2 enclosure fits standard indoor electrical rooms, and the FR943 frame aligns with common floor-mounted installations. Ensure proper 480 V primary and 208Y/120 V secondary feeder connections (wiring type 200X) and allow space for service clearance, ventilation, and future tap adjustments.
Key ratings include a 150 kVA, 60 Hz, three phase transformer with 480 V primary and 208Y/120 V secondary and a 0 degree phase shift. Tap settings are 2 at +2.5% and 4 at -2.5%, enabling compensation for voltage drop under load, which stabilizes secondary voltage, reduces trips, and improves drive and PLC control reliability.
Ideal for data centers, automotive, food and beverage, and general manufacturing environments with nonlinear loads such as drives and power supplies. The combination of harmonic mitigation, DOE 2016 efficiency, and robust enclosure makes it suitable for indoor factory floors and critical plant rooms requiring clean power and stable voltage for sensitive equipment.
The unit is UL Listed and meets DOE 2016 efficiency requirements, with NEMA 2 enclosure suitability for dry indoor environments and references to 10 CFR Part 431. These certifications support regulatory compliance, energy efficiency goals, and safer operation in regulated facilities.
With 150 kVA rating, rugged aluminum windings, and a 150°C insulation rise, the transformer is designed for long life with minimal maintenance. The stated warranty is one year from installation or 18 months from shipment. Expect ROI from energy savings, reduced cooling loads, and improved uptime due to enhanced power quality and voltage stability.
