Hammond Power Solutions SG3A0225BB - 3-Phase Transformer 225kVA 208D-208Y/120V

SG3A0225BB

Hammond Power Solutions SG3A0225BB is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 208V delta primary connection and delivers 225 kVA at 208Y/120V secondary voltage with aluminum windings rated for 150°C temperature rise and 220°C insulation class. Constructed with a Type 3R/IP24 enclosure finished in ANSI 61 grey, the transformer measures 52" H × 37.5" W × 34" D and operates at 55 dBA with 3-6.5% impedance. This transformer 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 plants, commercial facilities, and institutional buildings requiring reliable three-phase power conversion. Key Features & Specifications
