Hammond Power Solutions SK3A0075PB4K is a three-phase general duty transformer engineered for stepping down primary voltage in industrial power distribution systems. It converts a 600V delta primary connection to a 208Y/120V wye secondary output, with a 75 kVA capacity and ±2.5% and ±5% voltage adjustment taps for precise regulation. The unit weighs 700 lb and is housed in a Type 3R/IP24 rated enclosure measuring 36" H × 28.25" W × 27" D with an ANSI 61 grey finish, operating at a 150°C temperature rise with 220°C insulation class and a 50 dBA sound level. It complies with CSA and UL certifications, as well as DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5). Typical applications include commercial buildings, industrial facilities, and institutional power systems requiring reliable three-phase power conversion.
