Hammond Power Solutions SG3A0015BK - 3-Phase Transformer 15kVA 208D-480Y/277V

SG3A0015BK

Hammond Power Solutions SG3A0015BK is a three-phase general duty transformer designed for industrial power distribution applications. This 15 kVA unit features a 208V delta primary to 480Y/277V wye-n secondary configuration with 60Hz frequency and 2.5%-6.5% impedance range. Constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class, it features a Type 3R/IP24 enclosure with ANSI 61 grey finish measuring 21.88" H × 21.5" W × 20.12" D. The transformer complies with 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 45 dBA sound rating. Typical applications include commercial buildings, industrial facilities, and electrical distribution systems requiring reliable voltage transformation. Key Features & Specifications
