Hammond Power Solutions SH3T0030KB3K - 30 kVA Transformer 480D-208Y/120V Seismic Rated

SH3T0030KB3K

Hammond Power Solutions SH3T0030KB3K is a three-phase general duty transformer designed for industrial power distribution applications. This 30 kVA transformer features a 480V delta primary configuration with ±2.5% and ±5% voltage adjustment taps, delivering 208Y/120V secondary output through a zig-zag winding with neutral connection. Constructed with copper windings and housed in a Type 3R/IP24 rated enclosure measuring 28.75" H × 25.75" W × 23.8" D with ANSI 61 grey finish, the unit operates with 150°C temperature rise and 220°C insulation class. The transformer complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting OSHPD and IBC 2018 seismic requirements for Sds=2.0 with z/h=1 and lp=1.5. Typical applications include commercial buildings, industrial facilities, and institutional power systems requiring reliable three-phase power conversion with seismic resilience.
