Hammond Power Solutions SG3A0015KB - 3-Phase Transformer 15kVA 480D-208Y/120V

SG3A0015KB

Hammond Power Solutions SG3A0015KB is a three-phase general duty transformer designed for industrial power distribution applications. This 15 kVA unit features a 480V delta primary to 208Y/120V secondary configuration with 60Hz frequency and aluminum windings rated for 150°C temperature rise with 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 21.88" H × 21.5" W × 20.12" D, and operates at 45 dBA sound level with mechanical lug secondary terminations. It complies with 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 commercial buildings, industrial facilities, and infrastructure projects requiring reliable three-phase power conversion. Key Features & Specifications
