Hammond Power Solutions DM020JC - 3-Phase Transformer 20kVA 460D-230Y/133V

DM020JC

Hammond Power Solutions DM020JC is a three-phase general duty transformer designed for industrial power distribution applications. This 20 kVA unit features a 460V delta primary connection with ±5% FCAN/FCBN taps and delivers 230Y/133V secondary output through a wye-N configuration with mechanical lug terminations. The transformer is constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish measuring 28.75" H × 23.9" W × 25" D. It complies with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and operates at 45 dBA sound levels with 3-6% impedance on a 60Hz frequency. This transformer is commonly used in commercial and industrial facilities requiring reliable power conversion with Dyn1 vector configuration. Key Features & Specifications
