Hammond Power Solutions DM220JJC - 3-Phase Transformer 220kVA 460D-460Y/266V

DM220JJC

Hammond Power Solutions DM220JJC is a three-phase general duty transformer designed for industrial power distribution applications. It features a 460V delta primary and 460Y/266V wye-n secondary configuration with 220 kVA capacity operating at 60Hz frequency. The transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish, measuring 41" H × 32" W × 25.5" D, and maintains a 55 dBA sound level with 150°C temperature rise and 220°C insulation class. Compliant with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and approved for installation in US and LATAM markets, this unit features standard impedance range of 3.5% to 6.5% with Dyn1 vector configuration. Typical applications include industrial facilities requiring reliable three-phase power transformation with outdoor-rated protection. Key Features & Specifications
