Hammond Power Solutions SK3A0750PB3K - 3-Phase Transformer 750kVA 600D-208Y/120V

SK3A0750PB3K

Hammond Power Solutions SK3A0750PB3K is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 600V delta primary connection with multiple voltage taps and delivers 208Y/120V secondary power through a wye-N configuration with 750 kVA capacity. The transformer is housed in a Type 3R/IP24 rated enclosure measuring 64"H x 49"W x 39"D with ANSI 61 grey finish, providing robust outdoor protection while maintaining a 67 dBA sound level. It 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). This transformer is suitable for commercial buildings, industrial facilities, and utility applications requiring reliable three-phase power conversion with 150°C temperature rise and 220°C insulation class ratings.
