Hammond Power Solutions DM145NJC - 3-Phase Transformer 145kVA 575D-460Y/266V

DM145NJC

Hammond Power Solutions DM145NJC is a three-phase general duty transformer designed for industrial power distribution applications. This unit features a 575V delta primary connection with ±5% FCAN/FCBN taps and delivers 460Y/266V secondary output through a wye-N configuration with mechanical lug terminations. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 41" H × 32" W × 25.5" D, and operates with 150°C temperature rise using 220°C insulation class materials. It complies with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and NEMA ST-20 sound level requirements at 50 dBA, approved for installation in US and LATAM markets. Typical applications include industrial plants, manufacturing facilities, and commercial buildings requiring reliable three-phase power conversion. Key Features & Specifications
