Hammond Power Solutions SK3A0075KB9S is a three-phase general duty transformer engineered for voltage transformation in industrial power distribution systems. This 75 kVA unit converts 480V delta primary voltage to 208Y/120V secondary wye configuration, featuring aluminum windings with a 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R / IP24 enclosure with an ANSI 61 grey finish, weighing 560 lb, and operates at 60 Hz with a sound level of 50 dBA and impedance ranging from 2.5% to 6.5%. It complies with CSA and UL certifications, as well as DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5). Typical applications include industrial facilities, commercial buildings, and electrical distribution systems requiring reliable voltage transformation with mechanical lug terminations and electrostatic shielding.
