Hammond Power Solutions SK3A0030KB4K is a three-phase general duty transformer engineered for stepping down 480V delta primary voltage to 208Y/120V wye secondary in industrial and commercial power distribution systems. This 30 kVA unit operates at 60Hz with a 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish. The transformer weighs 325 lb and features mechanical lug terminations, 2x2.5% FCAN and 4x2.5% FCBN taps, and a sound level of 45 dBA with impedance ranging from 2.5% to 6.5%. 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 infrastructure projects requiring reliable power conversion.
