Hammond Power Solutions DM145JJ is a three-phase general duty transformer designed for industrial power distribution and voltage transformation. It features a 460V delta primary connection and a 460Y/266V wye secondary configuration with a 145 kVA capacity, operating at 60Hz with 3-6% impedance. The unit is constructed with aluminum windings rated for a 150°C temperature rise and 220°C insulation class, housed in a Type 3R/IP24 enclosure with an ANSI 61 grey finish, measuring 41"H × 32"W × 25.5"D and weighing 815 lb. It complies with CSA and UL certifications, IBC 2018 seismic standards (Sds=2.0, lp=1.5), and maintains 50 dBA sound levels per NEMA ST-20. Typical applications include industrial facilities requiring reliable power transformation with mechanical lug terminations and Dyn1 vector configuration.
