Hammond Power Solutions SK3A1000KK9K - Dry-Type Transformer 1000 kVA 480D-480Y/277V

SK3A1000KK9K

Hammond Power Solutions SK3A1000KK9K is a three-phase dry-type transformer designed for industrial power distribution applications. This 1000 kVA unit operates at 480V delta primary to 480Y/277V secondary configuration with 60Hz frequency, featuring a 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 72"H x 54"W x 44"D, and includes a single electrostatic shield with standard mounting pad terminations. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) with a sound level of 64 dBA. Typical applications include industrial plants, commercial facilities, and institutional power systems requiring reliable voltage transformation with 4-7.5% impedance characteristics.
