Hammond Power Solutions MG3A0300SBSAHC0 - 3-Phase Transformer 300kVA 4160V-208Y/120V

MG3A0300SBSAHC0

Hammond Power Solutions MG3A0300SBSAHC0 is a three-phase general duty transformer designed for industrial power distribution applications. This 300 kVA unit features a 4160V delta primary connection with ±5% voltage adjustment capability and delivers 208Y/120V secondary output through wye-N configuration. 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 64"H × 49"W × 39"D. The unit complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency standards while meeting IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5) and operating at 55 dBA sound levels per IEEE C57.12.01. Typical applications include industrial facilities, manufacturing plants, and commercial power systems requiring reliable medium-voltage to low-voltage power conversion.
