Hammond Power Solutions DM034KKCN - 3-Phase Transformer 34kVA 480D-480Y/277V

DM034KKCN

Hammond Power Solutions DM034KKCN is a three-phase general duty transformer designed for industrial power distribution applications. This transformer features a 480V delta primary configuration and delivers 480Y/277V secondary power with a 34 kVA capacity, operating at 60Hz frequency with 3-6% impedance. The unit is housed in a Type 3R/IP24 rated enclosure measuring 28.75" H × 23.9" W × 25" D with ANSI 61 grey finish, providing protection against rain and sleet. It complies with IBC 2018 seismic standards (Sds=2.0) and maintains a low 45 dBA sound level per NEMA ST-20 requirements. Typical applications include commercial buildings, industrial facilities, and power distribution systems requiring reliable voltage transformation. Key Features & Specifications
