Eaton Specification Sheet - X48M28B49CUEETRNON
Harmonic mitigation design reduces harmonic distortion and stabilizes current draw under nonlinear loads. This improves power quality, lowers THD, and reduces overheating risk across downstream equipment. Application: manufacturing lines and facilities with drives, UPS, and non-linear power supplies benefit from steadier voltage and longer asset life. High-capacity performance at 150 kVA with 480 V primary and 208Y/120 V secondary provides reliable feeder protection. Business impact: a single transformer can feed multiple critical loads with consistent voltage, reducing voltage sags and avoided downtime. Application: data centers, distribution feeders, and large commercial spaces. Copper windings and an 80 °C rise rating deliver durability and efficiency in rugged environments. Impact: copper windings offer lower resistance losses and better thermal performance, extending service life. Application: industrial plants where ambient temperatures and continuous operation are common. Tap changer with two +2.5% and four -2.5% taps enables precise voltage compensation for fluctuating input. Impact: maintains secondary voltage within tolerance, reducing equipment stress and improving process stability. Application: long feeders or sites with variable supply voltages. Electrostatic shielding and Weathershield WS34 add EMI protection and weather resilience. Impact: minimizes interference with control systems and protects against harsh outdoor or dusty indoor conditions. Application: outdoor installations or plant floors with dust and moisture exposure. Rugged enclosure and standards alignment ease installation. The unit is a dry-type, three-phase transformer in a NEMA 2 enclosure with a 918A frame and 200X wiring connection, weighing about 1800 lb. Impact: simplifies crane and rigging planning, accelerates commissioning, and reduces downtime across capital projects.

FAQs
Plan for craneable handling due to an approximate 1800 lb weight, secure 480 V three-phase input with 60 Hz supply, and mount in a NEMA 2 enclosure. Ensure 200X wiring connections are properly routed, allow clearance for access, and follow manufacturer torque specs for taps. Use the +2.5% and -2.5% tap settings to compensate for voltage fluctuations at the site.
The device is engineered as a harmonic mitigating transformer, which attenuates harmonic currents from nonlinear loads, reducing THD and stabilizing voltages. Copper windings and precise tap control minimize losses and heat, while UL Listed certification confirms safety and reliability for industrial environments with drives and nonlinear power equipment.
Yes. With a 150 kVA rating, 480 V primary and 208Y/120 V secondary, and a three-phase 60 Hz profile, it cleanly feeds critical loads while mitigating harmonics. Features like electrostatic shielding and the WS34 weather shield option improve EMI protection and environmental resilience, making it well suited for data centers and heavy manufacturing applications.
The unit is UL Listed and catalog notes reference NEMA TP-1 efficiency. It features an 80 °C rise rating, copper windings, a NEMA 2 enclosure, and a 918A frame. The product also includes a Certified Test Report and a durable electrostatic shield, aligning with typical industrial compliance requirements.
Expect lower maintenance needs due to a dry-type design and robust copper windings that resist thermal stress. Eaton provides a one-year warranty from installation or 18 months from shipment, whichever occurs first. ROI benefits come from improved power quality, reduced downtime, and longer asset life in facilities with nonlinear loads and critical processes.
