Hammond Power Solutions TE3A0118KKM - 3-Phase Transformer 118 kVA 480D-480Y/277V

TE3A0118KKM

Hammond Power Solutions TE3A0118KKM is a three-phase general duty transformer designed for industrial power distribution applications. This 118 kVA unit features a 480V delta primary connection and 480Y/277V wye secondary configuration with 60Hz frequency operation, delivering reliable power conversion with 2.5%-6.5% impedance and 150°C temperature rise capability. The transformer is housed in a Type 3R/IP24 rated enclosure measuring 36" H × 28.25" W × 27" D with ANSI 61 grey finish and mechanical lug terminations, constructed with 220°C insulation class and single electrostatic shield. It complies with NRCAN 2019 efficiency standards and IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5), maintaining 50 dBA sound levels per NEMA ST-20. Typical applications include industrial facilities, commercial buildings, and utility distribution systems requiring robust power transformation with Dyn1 vector configuration.
