Hammond Power Solutions SK3A0112PB9K - 112.5 kVA Transformer (600VΔ-208Y/120V)

SK3A0112PB9K

Hammond Power Solutions SK3A0112PB9K is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 600V delta primary configuration with multiple 2.5% taps and delivers 208Y/120V secondary output through a wye-n connection, providing 112.5 kVA capacity with 129.008 EKVA and meeting DOE 2016, NRCAN 2019, and NMX 2021 efficiency regulations. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 36" H × 28.25" W × 27" D, and operates with 150°C temperature rise, 220°C insulation class, and 50 dBA sound level. It complies with IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5) and features a Dyn1 vector configuration with 2.5%-6.5% impedance and mechanical lug secondary terminations. Typical applications include industrial facilities, commercial buildings, and institutional power systems requiring reliable three-phase power conversion. Key Features & Specifications
