Hammond Power Solutions SG3A0075DB0C - 3-Phase Transformer 75kVA 240D-208Y/120V

SG3A0075DB0C

Hammond Power Solutions SG3A0075DB0C is a three-phase general duty transformer designed for industrial power distribution applications. This 75 kVA unit converts 240V delta primary voltage to 208Y/120V wye-n secondary configuration 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 rated enclosure measuring 36 inches high by 28.25 inches wide by 27 inches deep, finished in ANSI 61 grey with mechanical lug secondary terminations. 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) and maintaining a 50 dBA sound level. Typical applications include commercial buildings, industrial facilities, and institutional power systems requiring reliable three-phase power conversion. Key Features & Specifications
