Hammond Power Solutions SK3A0030PK4S is a three-phase general duty transformer engineered for industrial and commercial power distribution applications requiring voltage conversion and isolation. This 30 kVA unit operates with a 600V delta primary and a 480Y/277V wye secondary, featuring aluminum windings with a 150°C temperature rise and 220°C insulation class. Housed in a Type 3R/IP24 rated enclosure with an ANSI 61 grey finish, the transformer measures 28.75 inches high by 25.75 inches wide by 23.8 inches deep and weighs 290 lb, operating at a quiet 45 dBA sound level. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets seismic standards including OSHPD and IBC 2018 with parameters Sds=2.0, z/h=1, and lp=1.5. Typical applications include industrial facilities, commercial buildings, and infrastructure projects requiring reliable three-phase power conversion with seismic resilience.
