Hammond Power Solutions SG3C0045KD is a dry-type distribution transformer from the Sentinel G family, engineered for stepping down three-phase power in industrial and commercial settings. This 45 kVA unit accepts a 480V delta primary and delivers a 240/120V secondary, housed in a rugged Type 3R/IP24 enclosure with dimensions of 28.8 inches in height, 25.8 inches in width, and 23.8 inches in depth, weighing 374 lb. It is constructed with aluminum windings rated for a 150°C temperature rise and 220°C insulation class, operating at a quiet 45 dBA sound level. The transformer complies with CSA and UL certifications, as well as DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets seismic standards including OSHPD and IBC 2018 with Sds=2.0, z/h=1, and lp=1.5 parameters. Typical applications include industrial facilities, commercial buildings, and infrastructure projects requiring reliable power transformation with seismic resilience.
