Hammond Power Solutions SK3A0030KB9S is a three-phase general duty transformer engineered for stepping down primary voltage in industrial power distribution systems. This 30 kVA unit converts a 480V delta primary to a 208Y/120V wye secondary, utilizing aluminum windings and operating at 60Hz with a 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R / IP24 rated enclosure with an ANSI 61 grey finish, weighing 290 lb, and produces a maximum sound level of 45 dBA. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting seismic standards including OSHPD and IBC 2018 with parameters Sds=2.0, z/h=1, and lp=1.5. Typical applications include commercial buildings and industrial facilities requiring reliable three-phase power conversion with seismic resilience.
