Hammond Power Solutions SK3A0500KB3K is a three-phase general duty transformer designed for voltage transformation in industrial power distribution systems. This 500 kVA unit operates with a 480V delta primary connection and provides a 208Y/120V secondary output with a Dyn1 vector configuration. The transformer is housed in a Type 3R/IP24 rated enclosure with an ANSI 61 grey finish, weighing 3350 lb, and measures 64"H x 49"W x 39"D. 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 with an Sds=2.0 rating. Typical applications include industrial facilities, commercial buildings, and institutional power systems requiring reliable voltage transformation.
