Hammond Power Solutions SK3A0225PK3K - 3-Phase Transformer 225kVA 600D/480Y

SK3A0225PK3K

Hammond Power Solutions SK3A0225PK3K is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 600V delta primary and 480Y/277V wye secondary configuration with 225 kVA capacity, operating at 60Hz with 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 44.5 inches high by 31.5 inches wide by 29.5 inches deep, and includes mechanical lug secondary terminations with single electrostatic shielding. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5) and maintaining a 58 dBA sound level. Typical applications include industrial facilities, manufacturing plants, and commercial buildings requiring reliable three-phase power conversion. Key Features & Specifications
