Hammond Power Solutions SG3A1000KY - 1000 kVA Transformer (Type 3R Enclosure)

SG3A1000KY

Hammond Power Solutions SG3A1000KY is a three-phase general duty transformer designed for industrial power distribution applications. This 1000 kVA unit features a 480V delta primary connection with multiple secondary voltage configurations (430Y/248V, 416Y/240V, 400Y/231V, 380Y/219V) and operates at 60Hz frequency with standard impedance ranging from 4% to 7.5%. Constructed with aluminum windings and housed in a Type 3R/IP24 rated enclosure finished in ANSI 61 grey, the transformer maintains a 150°C temperature rise with 220°C insulation class and produces 64 dBA maximum sound levels. The unit complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5). Typical applications include manufacturing facilities, commercial buildings, and industrial plants requiring reliable power transformation with outdoor environmental protection.
