Hammond Power Solutions SK3A0030KB3K is a three-phase general duty transformer engineered for voltage transformation in industrial power distribution systems. It converts a 480V delta primary to a 208Y/120V secondary with a 30 kVA rating, operating at 60Hz with a Dyn1 vector configuration. The unit features a Type 3R/IP24 enclosure with an ANSI 61 grey finish, weighs 325 lb, and measures 28.75" H × 25.75" W × 23.8" D, with a 150°C temperature rise and 220°C insulation class. It complies with CSA and UL certifications, as well as DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets OSHPD and IBC 2018 seismic requirements (Sds=2.0, z/h=1, lp=1.5). Typical applications include commercial buildings, industrial facilities, and electrical distribution systems requiring reliable voltage transformation with seismic resilience.
