FAQs
For 480 V delta primary operation, plan a three-phase pad or rack mount in a dry, ventilated area with NEMA 2 protection. Ensure proper clearance for cooling, verify tapping instructions for voltage regulation, and integrate with compatible switchgear to handle fault current. Flexibility with 2 AT +2.5% and 4 AT -2.5% taps aids in maintaining desired secondary voltages under varying loads.
Copper windings reduce I2R losses and improve heat dissipation, while DOE2016 efficiency ratings minimize no-load and load losses. The combined effect lowers energy consumption and operational costs over the transformer's life, particularly in continuous-duty solar and industrial applications where steady loads are common.
Yes. The NEMA 2 enclosure supports indoor and sheltered outdoor installations, and the WS62 weather-shield option enhances outdoor durability. With UL Listed certification and a 60 Hz, 300 kVA, three-phase configuration, it is well-suited for solar farms, outdoor substations near data centers, and other demanding, regulated environments.
The unit is UL Listed and DOE2016 Efficient, with 10 CFR Part 431 (2016) Efficient notes, ensuring compliance for energy performance. The NEMA 2 enclosure provides appropriate protection, and the FR945 frame along with 150 °C insulation supports robust, code-compliant operation in industrial settings.
The transformer offers long service life thanks to copper windings, precise taps, and rugged construction, reducing replacement frequency. DOE2016 efficiency lowers energy costs, while UL certification simplifies maintenance audits. With reliable cooling and enclosure protection, maintenance intervals are extended, delivering a favorable total cost of ownership for solar and industrial deployments.
