Hammond Power Solutions SG3A0300KB is a three-phase general duty transformer engineered for converting 480V delta primary power to 208Y/120V secondary output in industrial and commercial power distribution systems. This 300 kVA unit features aluminum windings with a 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish. The transformer complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency standards, meets IBC 2018 seismic requirements with Sds=2.0, and operates at 55 dBA sound levels. Typical applications include power distribution in commercial buildings, manufacturing facilities, and industrial plants requiring reliable three-phase voltage conversion.
