Hammond Power Solutions SH3T0750KB3S - 750 kVA Transformer 480D-208Y/120V

SH3T0750KB3S

Hammond Power Solutions SH3T0750KB3S is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 480V delta primary and 208Y/120V zig-zag secondary configuration with 750 kVA standard capacity, operating at 60Hz frequency with 4-7.5% impedance. The transformer is housed in a Type 3R/IP24 enclosure measuring 82"H x 60"W x 47"D with ANSI 61 grey finish, designed for 150°C temperature rise and 220°C insulation class. 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 67 dBA sound rating. Typical applications include industrial facilities, commercial buildings, and power distribution systems requiring reliable three-phase power conversion. Key Features & Specifications
