Hammond Power Solutions SK3A0500KB9S is a three-phase general duty transformer engineered for industrial power distribution, converting 480V delta primary input to a 208Y/120V secondary output with a wye-N configuration. This 500 kVA unit features aluminum windings rated for a 150°C temperature rise and 220°C insulation class, operating at 60 Hz with 4-7.5% impedance and a 60 dBA sound level. Housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish, the transformer measures 64 inches high by 49 inches wide by 39 inches deep and weighs 2950 lb. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations, along with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5), and holds CSA and UL certifications. Typical applications include industrial facilities, commercial buildings, and institutional power systems requiring reliable three-phase power conversion.
