Hammond Power Solutions SG3A0500KY - 3-Phase Transformer 500 kVA (Type 3R/IP24)

SG3A0500KY

Hammond Power Solutions SG3A0500KY is a three-phase general duty transformer designed for industrial power distribution applications. This 500 kVA transformer features a 480V delta primary connection with multiple voltage taps and delivers secondary voltages of 430Y/248V, 416Y/240V, 400Y/231V, or 380Y/219V through its wye-N configuration. Constructed with aluminum windings and housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, the unit measures 72" H × 54" W × 44" D and operates with a 150°C temperature rise and 220°C insulation class. The transformer complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards with Sds=2.0 and maintaining a 60 dBA sound level. Typical applications include industrial facilities, manufacturing plants, and commercial power systems requiring reliable three-phase power conversion. Key Features & Specifications
