Hammond Power Solutions DM550NJ - 3-Phase Transformer 550kVA 575D/460Y

DM550NJ

Hammond Power Solutions DM550NJ is a three-phase general duty transformer designed for industrial power distribution applications. This 550 kVA unit converts 575V delta primary voltage to 460Y/266V wye-n secondary voltage with a standard impedance range of 4.5% to 7% and operates at 60Hz frequency. Constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class, the transformer features a Type 3R/IP24 enclosure with ANSI 61 grey finish measuring 59"H × 48.5"W × 38"D. The unit complies with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5), produces 62 dBA maximum sound level per NEMA ST-20, and is approved for installation in US and LATAM markets. Typical applications include industrial facilities requiring reliable power conversion with Dyn1 vector configuration and mounting pad secondary terminations. Key Features & Specifications
