Hammond Power Solutions DM011BK - 3-Phase Transformer 11kVA 208D-480Y/277V

DM011BK

Hammond Power Solutions DM011BK is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 208V delta primary connection and delivers 480Y/277V secondary output with 11 kVA capacity, operating at 60Hz frequency with 3-6% impedance. 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 design complies with IBC 2018 seismic standards (Sds=2.0, lp=1.5) and maintains a 45 dBA sound level per NEMA ST-20, while being approved for installation in US and LATAM markets. Typical applications include commercial and industrial facilities requiring reliable voltage transformation with secondary terminal block connections and YNd1 vector configuration.
