Hammond Power Solutions SG3A0030KK is a three-phase general duty transformer engineered for industrial power distribution applications. It features a 480V delta primary and 480Y/277V wye secondary configuration with 30 kVA capacity, constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class. Housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish, the unit measures 28.75" H × 25.75" W × 23.8" D and weighs 300 lb. The transformer meets DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while providing seismic compliance with OSHPD and IBC 2018 standards (Sds=2.0, z/h=1, lp=1.5). Typical applications include commercial buildings, industrial facilities, and infrastructure projects requiring reliable power transformation with 45 dBA sound levels and mechanical lug terminations.
