Hammond Power Solutions DM075NNC - 3-Phase Transformer 75 kVA (575V Delta-Wye)

DM075NNC

Hammond Power Solutions DM075NNC is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 575V delta primary configuration with ±5% FCAN/FCBN taps and delivers 575Y/332V secondary output through a wye connection with neutral. Constructed with a Type 3R/IP24 rated enclosure finished in ANSI 61 grey, the transformer measures 38" H × 26" W × 21" D and operates with 150°C temperature rise using 220°C insulation class materials. Compliant with IBC 2018 seismic standards (Sds=2.0) and NEMA ST-20 sound requirements at 50 dBA, this 75 kVA transformer is approved for installation in both US and LATAM markets. Typical applications include industrial plants, manufacturing facilities, and commercial power systems requiring reliable three-phase power conversion. Key Features & Specifications
