Hammond Power Solutions SH3T0225KB3K - 225 kVA Transformer 480D-208Y/120V

SH3T0225KB3K

Hammond Power Solutions SH3T0225KB3K is a three-phase general duty transformer designed for industrial power distribution applications. This 225 kVA unit features a 480V delta primary connection with multiple voltage taps and delivers 208Y/120V secondary power through a zig-zag configuration with neutral. Constructed with copper windings and rated for 150°C temperature rise with 220°C insulation class, the transformer is housed in a Type 3R/IP24 enclosure measuring 44.5" H × 31.5" W × 29.5" D with ANSI 61 grey finish. The unit complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency standards while meeting IBC 2018 seismic requirements (Sds=2.0, z/h=1, lp=1.5) and operating at 58 dBA sound levels. Typical applications include industrial facilities, commercial buildings, and institutional power systems requiring reliable three-phase power conversion. Key Features & Specifications
