Hammond Power Solutions SK3A1000PB3S - 3-Phase Transformer 1000kVA 600D-208Y/120V

SK3A1000PB3S

Hammond Power Solutions SK3A1000PB3S is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 600V delta primary configuration stepping down to 208Y/120V secondary with a 1000 kVA capacity and operates at 60Hz with a standard impedance range of 4% to 7.5%. Constructed with aluminum windings and housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, the transformer measures 82"H x 60"W x 47"D and is designed for 150°C temperature rise with 220°C insulation class. The transformer complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations and meets IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5) while operating at 67 dBA sound levels. Typical applications include industrial facilities, manufacturing plants, and commercial buildings requiring reliable three-phase power conversion with electrostatic shielding and mounting pad terminations.
