Hammond Power Solutions SK3A0030PB4S - 30 kVA Transformer 600D-208Y/120V

SK3A0030PB4S

Hammond Power Solutions SK3A0030PB4S is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 600V delta primary configuration with 2x2.5% FCAN and 4x2.5% FCBN taps, delivering 208Y/120V secondary output through wye-N connection with mechanical lug terminations. Constructed with aluminum windings rated for 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 28.75" H × 25.75" W × 23.8" D. The design complies with DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations while meeting OSHPD and IBC 2018 seismic requirements (Sds=2.0, z/h=1, lp=1.5) with a 45 dBA sound rating. Typical applications include industrial facilities, commercial buildings, and infrastructure projects requiring reliable 30 kVA power conversion with seismic resilience.
