Eaton Specification Sheet - X48M28F33TCUEEPOS
Copper windings and a robust 300 kVA rating deliver low-resistance performance and efficient heat management, translating into lower energy loss and cooler operation for critical loads. In a three-phase 60 Hz system, this dry-type transformer reduces voltage drop and ensures steady secondary voltages for sensitive equipment across manufacturing lines and data centers. Tap changes provide voltage regulation, with 2 taps at +2.5% and 4 taps at -2.5%, enabling better accommodation of voltage swings from PV installations and fluctuating loads, which reduces equipment stress and trip risk. Weathershield WS35 and dry-type construction enable outdoor installation and easier maintenance, extending service life in challenging environments. Electrostatic shielding minimizes EMI, protecting adjacent control systems and communications networks in complex industrial facilities. Certifications and warranty support compliance and lifecycle value: UL Listed, NEMA TP-1 Compliant, NEMA TP-1 efficient, and Eaton’s standard warranty of one year from installation or eighteen months from shipment, with a thermal indicator for proactive maintenance. The transformer’s compact footprint, copper windings, 115°C rise, and copper wiring connection of 201X simplify integration with existing distribution panels and bus systems, while its three-phase 60 Hz operation aligns with standard plant wiring practices and safety requirements.

FAQs
Yes. The unit is designed for 480 V primary and 208Y/120 V secondary in three-phase, 60 Hz systems. It uses a 201X wiring connection and a 919X frame, with taps at +2.5% and -2.5% to accommodate voltage variations typical in distributed power networks.
The WS35 weather shield enables outdoor installation by protecting the dry-type transformer from environmental exposure. Combined with copper windings and a robust 300 kVA rating, it supports reliable operation in outdoor substations or perimeter distribution areas with reduced maintenance needs.
This transformer is UL Listed and NEMA TP-1 Compliant, with NEMA TP-1 efficient notes. These certifications affirm safety, reliability, and energy efficiency in code-driven industrial environments, aiding procurement and commissioning in regulated facilities.
The harmonically mitigated design reduces voltage distortion from nonlinear loads, improving power factor and reducing thermal stress on downstream equipment. This translates to fewer nuisance trips, longer equipment life, and lower maintenance costs in facilities with pumps, drives, and inverter-based loads.
Warranty terms are Eaton Selling Policy 25-000, one year from installation or eighteen months from shipment, whichever comes first. Maintenance indicators include a thermal indicator for proactive monitoring and copper windings known for long-term reliability, minimizing unexpected downtime.
