Hammond Power Solutions MG3A1000SKSCHC0 - 3-Phase Transformer 1000kVA 4160D/480Y

MG3A1000SKSCHC0

Hammond Power Solutions MG3A1000SKSCHC0 is a three-phase general duty transformer designed for industrial power distribution applications. This 1000 kVA unit features a 4160V delta primary configuration with ±5% voltage regulation and steps down to 480Y/277V wye secondary output, operating at 60Hz frequency with 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 72" H × 54" W × 44" D, and produces a maximum sound level of 64 dBA per IEEE C57.12.01 standards. It complies with multiple efficiency regulations including DOE 2016, NRCAN 2019, and NMX 2021, while meeting IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5). Typical applications include industrial plants, commercial facilities, and institutional buildings requiring reliable medium-voltage to low-voltage power conversion. Key Features & Specifications
