Hammond Power Solutions SG3A0150DK - 3-Phase Transformer 150kVA 240D-480Y/277V

SG3A0150DK

Hammond Power Solutions SG3A0150DK is a three-phase general duty transformer designed for industrial power distribution applications. This 150 kVA unit features a 240V delta primary connection with multiple voltage taps and delivers 480Y/277V secondary power through wye-N configuration with mechanical lug terminations. Constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class, the transformer is housed in a Type 3R/IP24 enclosure measuring 44.5×31.5×29.5 inches with ANSI 61 grey finish. The unit complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards with Sds=2.0 and operating at 50 dBA sound levels. Typical applications include industrial facilities, manufacturing plants, and commercial buildings requiring reliable three-phase power conversion. Key Features & Specifications
