Hammond Power Solutions SH3T0300PB3K - 3-Phase Transformer 300kVA 600D/208Z

SH3T0300PB3K

Hammond Power Solutions SH3T0300PB3K is a three-phase general duty transformer designed for industrial power distribution applications. This 300 kVA unit features a 600V delta primary and 208Y/120V zig-zag secondary configuration with copper windings, operating at 60Hz frequency with 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 52"H × 37.5"W × 34"D, and produces 58 dBA maximum sound levels. It complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency standards while meeting IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5). Typical applications include commercial buildings, industrial facilities, and institutional power systems requiring reliable voltage transformation with 4-7.5% impedance characteristics.
