Hammond Power Solutions SG3A1000KB - 3-Phase Transformer 1000kVA 480D-208Y/120V

SG3A1000KB

Hammond Power Solutions SG3A1000KB is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 480V delta primary configuration with 2x2.5% FCAN and FCBN taps, delivering 208Y/120V secondary output through wye-N connection at 1000 kVA capacity. Constructed with aluminum windings rated for 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 82" H x 60" W x 47" D. The design 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) and maintaining 64 dBA sound levels. Typical applications include industrial facilities, commercial buildings, and institutional power systems requiring reliable voltage transformation with 4-7.5% impedance characteristics.
