Hammond Power Solutions SG3A0030BB - 3-Phase Transformer 30kVA 208D-208Y/120V

SG3A0030BB

Hammond Power Solutions SG3A0030BB is a three-phase general duty transformer designed for industrial power distribution applications. This 30 kVA transformer features a 208V delta primary and 208Y/120V secondary configuration with aluminum windings rated for 150°C temperature rise and 220°C insulation class. The unit is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 28.75" H × 25.75" W × 23.8" D, and operates at 45 dBA sound level with mechanical lug terminations. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting seismic standards including OSHPD and IBC 2018 with Sds=2.0, z/h=1, and lp=1.5 parameters. Typical applications include commercial buildings, industrial facilities, and infrastructure projects requiring reliable three-phase power conversion with seismic resilience.
