Selling Policy 25-000 - Distribution and Control Products and Services
Copper windings with electrostatic shielding improve dielectric strength and heat dissipation, reducing losses and extending transformer life while delivering cleaner power to sensitive loads. This translates to fewer nuisance trips in drives, PLCs, and data-center equipment, and lowers maintenance costs over the life of the installation. Tapped voltage regulation provides resilience against load fluctuations, enabling steady voltages for motors and control circuits without overdesigning the electrical room. The combination of UL Listed and NEMA TP-1 compliant, along with NEMA TP-1 efficiency, ensures code compliance and energy performance, reducing utility penalties and aligning with corporate sustainability goals. Dry-type construction offers a safer, oil-free solution with minimal fire risk in indoor or semi-enclosed spaces. Weathershield WS35 enables outdoor applicability where necessary, while the robust 919X frame and 201X wiring compatibility simplify installation in standard switchgear. Overall, the unit supports scalable power management in 60 Hz environments, delivering predictable performance for evolving facility loads.

FAQs
The X48M28B33CUEENON is a 480V primary, 208Y/120V secondary, three-phase dry-type transformer designed for standard 60 Hz power systems. With a 201X wiring connection and a 919X frame, it integrates with typical switchgear and control panels. Its copper windings and electrostatic shielding support reliable operation in populated equipment rooms, while UL and NEMA TP-1 certifications ensure compliance for new or retrofit installations.
Key specs include a 300 kVA rating, 480 V primary, 208Y/120 V secondary, 60 Hz, three-phase, and 0° phase shift. It features taps at +2.5% and -2.5% (2 at +2.5%, 4 at -2.5%), copper windings, and an 80 °C rise rating. The unit is UL Listed, NEMA TP-1 compliant, and designed for efficient, reliable power conditioning in demanding environments.
Yes. With a 480V primary and 208Y/120V secondary, the X48M28B33CUEENON is well-suited for PV systems feeding commercial or industrial loads. Its harmonic mitigation, voltage regulation capabilities, and 60 Hz compatibility help maintain power quality in facilities integrating solar or other renewables, reducing voltage distortion and improving the reliability of critical equipment.
The unit is UL Listed and NEMA TP-1 Compliant, with a NEMA TP-1 efficient design. These certifications indicate compliance with safety and energy-efficiency standards, which simplify code approvals, guarantee performance expectations, and support energy-management initiatives across facilities. The combination of these certifications helps reduce risk during procurement and installation while ensuring long-term reliability.
Warranty terms reflect Eaton’s policy: one year from installation or eighteen months from shipment, whichever comes first. Routine maintenance should focus on verifying insulation integrity, connections (201X wiring), and protection devices. For ROI, consider the reliability gains from UL/NEMA TP-1 compliance, copper windings, and robust build, which translate to lower downtime and longer service life.
