Hammond Power Solutions SK3A0030KB4S is a three-phase general duty transformer engineered for voltage transformation in commercial and industrial power distribution systems. It converts a 480V delta primary to a 208Y/120V secondary with a 30 kVA capacity, utilizing aluminum windings rated for a 150°C temperature rise and 220°C insulation class. The unit is housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish, weighs 290 lb, and operates at a quiet 45 dBA sound level. 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. Typical applications include commercial buildings, industrial facilities, and infrastructure projects requiring reliable voltage transformation with seismic resilience.
