Hammond Power Solutions SG3A0750BK is a three-phase general duty transformer engineered for stepping up voltage from 208V delta to 480Y/277V Wye in industrial power distribution systems. This 750 kVA unit features aluminum windings with a 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish. The transformer weighs 4990 lb and operates at a sound level of 64 dBA with 4-7.5% impedance. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5). Typical applications include industrial facilities, manufacturing plants, and commercial power systems requiring reliable voltage transformation.
