Hammond Power Solutions SK3A0750KB9K is a three-phase general duty transformer engineered for stepping down primary voltage in industrial power distribution networks. It converts a 480V delta primary to a 208Y/120V secondary with a 750 kVA capacity, operating at 60Hz with 4-7.5% impedance. The unit is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, weighing 5.19 lb, and features 150°C temperature rise with 220°C insulation class materials. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets IBC 2018 seismic standards (Sds=2.0) with CSA and UL certifications. Typical applications include industrial facilities, manufacturing plants, and commercial buildings requiring reliable power transformation with Dyn1 vector configuration and single electrostatic shielding.
