Hammond Power Solutions SG3A0045DB is a three-phase general duty transformer engineered for industrial power distribution applications requiring reliable voltage conversion. This 45 kVA unit operates with a 240V delta primary configuration and delivers 208Y/120V secondary power, featuring aluminum windings rated for 150°C temperature rise with 220°C insulation class. Housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, the transformer measures 28.75" H × 25.75" W × 23.8" D and weighs 370 lb. It complies with CSA and UL certifications, as well as DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, while meeting OSHPD and IBC 2018 seismic requirements (Sds=2.0, z/h=1, lp=1.5) with a Dyn1 vector configuration. Typical applications include commercial buildings, industrial facilities, and infrastructure projects requiring three-phase power conversion with seismic compliance.
