Hammond Power Solutions SG3A0500KY is a three-phase general duty transformer engineered for industrial power distribution, converting a 480V delta primary connection to multiple secondary wye-N voltages including 430Y/248V, 416Y/240V, 400Y/231V, and 380Y/219V. This 500 kVA unit features aluminum windings with a 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 rated enclosure with an ANSI 61 grey finish. The transformer complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, meets IBC 2018 seismic standards with Sds=2.0, and maintains a 60 dBA sound level per NEMA ST-20. Typical applications include industrial facilities, manufacturing plants, and commercial power systems requiring reliable three-phase power conversion.
