Hammond Power Solutions DM040KDC is a three-phase general duty transformer designed for industrial power distribution, providing reliable voltage transformation from a 480V delta primary to a 240Y/139V wye-N secondary with a 40 kVA capacity. It operates at 60Hz with a 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 rated enclosure measuring 28.75" H × 23.9" W × 25" D with an ANSI 61 grey finish and weighing 355 lb. The transformer complies with CSA and UL certifications, meets IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5), and maintains a 45 dBA sound level per NEMA ST-20. It is suitable for applications in manufacturing facilities, commercial buildings, and power distribution systems requiring reliable voltage transformation.
