FAQs
Install the X48M28B33CUEETHR on a sturdy, level surface capable of supporting its substantial weight (approximately 4,417 lb). Ensure adequate clearance for ventilation, access to wiring connection 203X, and serviceability around the EE frame 919X. Plan for the WS35 weather shield where outdoor exposure is possible, and confirm 480 V input with 208Y/120 V secondary wiring compatibility in a three-phase, 60 Hz system.
Key specs include a 300 kVA rating, primary voltage of 480 V, secondary voltage of 208 Y/120 V, three-phase configuration, 60 Hz frequency, and a -30° phase shift. Taps are provided at +2.5% and -2.5% to support voltage regulation. Copper windings in an EE frame 919X deliver robust thermal performance and reliable operation in industrial environments.
Yes. The transformer is UL Listed, which confirms adherence to recognized safety standards. It is also NEMA TP-1 compliant and cataloged as NEMA TP-1 efficient, ensuring compliance with recognized power distribution performance requirements. These certifications support safer operation, easier procurement, and long-term reliability in regulated industrial settings.
The transformer mitigates harmonic distortion produced by nonlinear loads, reducing voltage distortion and waveform-related losses. This protects connected equipment, lowers maintenance costs, and enhances system efficiency. Its copper windings, electrostatic shielding, and TP-1 efficient design help maintain consistent voltage regulation in demanding facilities such as manufacturing plants and data centers.
The unit occupies a substantial footprint with dimensions around 36.23 in (length) × 75 in (height) × 44.2 in (width) and a weight near 4,417 lb. Plan for proper hoisting, ventilation, and service access. Warranty terms are 1 year from installation or 18 months from shipment. Its copper windings, 480 V/208Y-120 V configuration, and heavy-duty WS35 weather shield support rugged, long-term usage.
