Hammond Power Solutions SK3A0045KB9K is a three-phase general duty transformer designed for stepping down 480V delta primary voltage to 208Y/120V wye-N secondary voltage in industrial power distribution systems. This 45 kVA unit operates at 60Hz with a 150°C temperature rise and 220°C insulation class, featuring an impedance range of 2.5% to 6.5%. It is housed in a Type 3R/IP24 rated enclosure with an ANSI 61 grey finish, measuring 28.75 inches high by 25.75 inches wide by 23.8 inches deep, and weighing 430 lb, with mechanical lug secondary terminations and a single electrostatic shield. The transformer complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, and meets OSHPD and IBC 2018 seismic requirements (Sds=2.0, z/h=1, lp=1.5) with a 45 dBA sound level rating. Typical applications include commercial buildings, industrial facilities, and institutional power systems requiring reliable voltage transformation with seismic compliance.
