Hammond Power Solutions SG3A0750BB0C - 3-Phase Transformer 750kVA (208D-208Y/120V)

SG3A0750BB0C

Hammond Power Solutions SG3A0750BB0C is a three-phase general duty transformer designed for industrial power distribution applications. This 750 kVA unit operates at 208V delta primary to 208Y/120V secondary configuration with 60Hz frequency, featuring a 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 64"H × 49"W × 39"D, and produces 64 dBA maximum sound levels. It 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 industrial facilities, commercial buildings, and utility power distribution systems requiring reliable three-phase power conversion. Key Features & Specifications
