Hammond Power Solutions SK3A0030PK3S is a three-phase dry-type transformer engineered for industrial power distribution and voltage conversion. It steps down a 600V delta primary to a 480Y/277V wye secondary, delivering 30 kVA of capacity with aluminum windings rated for a 150°C temperature rise and 220°C insulation class. The unit is housed in a Type 3R / IP24 enclosure finished in ANSI 61 grey, measuring 28.75 inches high by 25.75 inches wide by 23.8 inches deep, and weighs 295 lb. 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 for Sds=2.0 conditions. Typical applications include industrial facilities, commercial buildings, and infrastructure projects requiring reliable three-phase power conversion with seismic resilience.
