Hammond Power Solutions SG3A0150KK - 3-Phase Transformer 150kVA 480D-480Y/277V

SG3A0150KK

Hammond Power Solutions SG3A0150KK is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 480V delta primary connection and delivers 480Y/277V secondary voltage through a wye-N configuration with 150 kVA capacity. 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 with ANSI 61 grey finish measuring 44.5 inches high by 31.5 inches wide by 29.5 inches deep. The design complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards with Sds=2.0, z/h=1, and lp=1.5 parameters. Typical applications include industrial facilities, commercial buildings, and manufacturing plants requiring reliable three-phase power transformation with 60Hz operation and 50 dBA sound level performance.
