Hammond Power Solutions SG3A0225KK is a three-phase general duty transformer engineered for industrial power distribution, converting 480V delta primary input to 480Y/277V wye secondary output. This 225 kVA unit operates at 60Hz with aluminum windings rated for a 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish. The transformer measures 52 inches high by 37.5 inches wide by 34 inches deep, weighs 1400 lb, and maintains a sound level of 55 dBA. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, is certified to CSA and UL standards, and meets IBC 2018 seismic requirements with Sds=2.0. Typical applications include industrial facilities, commercial buildings, and manufacturing plants requiring reliable three-phase power conversion.
