Hammond Power Solutions DM011KD - 3-Phase Transformer 11kVA 480D-240Y/139V

DM011KD

Hammond Power Solutions DM011KD is a three-phase general duty transformer designed for industrial power distribution applications. This 11 kVA unit features a 480V delta primary connection and delivers 240Y/139V secondary output through a wye-N configuration with Dyn1 vector grouping. Constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class, the transformer is housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish measuring 21.5" H × 19.38" W × 20.2" D. The unit complies with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and operates at 45 dBA sound level with 3-6% impedance, making it suitable for commercial and industrial facilities requiring reliable power conversion.
