FAQs
This unit is a three-phase dry-type transformer with a 919X frame and a WeatherShield WS35 enclosure. Plan for sufficient clearance around the 75 inch height, 44.2 inch width, and 36.23 inch depth, and ensure a stable mounting surface. Wiring connections use 203X terminals, and the unit supports taps at +2.5% and -2.5% to accommodate voltage variation on 480 V primary feeds.
The X48M28T22CUEETHR is designed to reduce harmonic currents in a three-phase system with a 60 Hz duty cycle and a -30 degree phase shift. By providing clean, regulated secondary voltage at 208Y/120 V from a 480 V source, it minimizes distortion that can trip breakers and shorten equipment life, especially in facilities with nonlinear drives and power electronics.
Yes. The unit is UL Listed and NEMA TP-1 Compliant, with a TP-1 efficiency designation per Eaton’s catalog notes. These certifications ensure it meets strict safety, performance, and energy efficiency requirements, making it suitable for commercial distribution panels, data centers, and manufacturing floors that require validated power quality.
The transformer carries Eaton’s warranty policy of one year from the date of installation or eighteen months from the date of shipment, whichever occurs first. Manufacturers’ protection is complemented by its rugged copper windings, electrostatic shielding, and WeatherShield WS35, which collectively support long-term reliability with lower maintenance.
The combination of copper windings, NEMA TP-1 efficiency designation, and harmonic mitigation translates to lower I2R losses, improved voltage regulation, and reduced downtime due to power quality events. For facilities with nonlinear loads, this translates into longer equipment life, fewer trips, and more predictable energy costs across peak and off-peak operation.
