FAQs
This is a three-phase, 60 Hz dry-type distribution transformer with a 480 V primary and 208 Y/120 V secondary. Plan for the unit’s dimensions (36.23 in depth, 75 in height, 44.2 in width) and weight (approximately 3370 lb). Ensure proper clearance, ventilation, and mounting in a protected indoor or WS35-weather-shielded area to meet code and performance expectations.
The unit provides a 15° phase shift, 225 kVA rating, and copper windings, combined with NEMA TP-1 compliance and electrostatic shielding. These features reduce harmonic currents, improve efficiency, and minimize losses under nonlinear loading conditions, with tap changes to help maintain voltage regulation under varying demand.
Yes. It is designed for harmonic mitigation in PV and industrial facilities. The 480 V primary suits utility-scale or commercial PV, while 208Y/120 V secondary supports common control and lighting loads. The taps (+2.5% / -2.5%) help maintain stable voltages across changing irradiance and load profiles typical in renewables and manufacturing environments.
The transformer is UL Listed and NEMA TP-1 Compliant, with NEMA TP-1 efficient characteristics noted. These certifications ensure safety, energy efficiency, and regulatory compliance, simplifying approval processes and reducing risk during commissioning for regulated facilities and projects with strict electrical standards.
Warranty follows Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever comes first. Maintenance typically focuses on periodic thermal indicator checks, insulation integrity, and inspection of taps and connections. Copper windings offer durability and longevity in demanding environments, supporting lower maintenance costs over time.
