Hammond Power Solutions SG3A0225KB0C - 3-Phase Transformer 225kVA 480D-208Y/120V

SG3A0225KB0C

Hammond Power Solutions SG3A0225KB0C is a three-phase general duty transformer designed for industrial power distribution applications. This 225 kVA unit converts 480V delta primary voltage to 208Y/120V wye-n secondary voltage with a 60Hz operating frequency and features a 150°C temperature rise with 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 44.5 inches high by 31.5 inches wide by 29.5 inches deep, and operates at 55 dBA 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=1, lp=1.5). Typical applications include industrial facilities, commercial buildings, and power distribution systems requiring reliable voltage transformation. Key Features & Specifications
