Hammond Power Solutions DM175KKC - 3-Phase Transformer 175 kVA (480D-480Y/277V)

DM175KKC

Hammond Power Solutions DM175KKC is a three-phase general duty transformer designed for industrial power distribution applications. It features a 480V delta primary configuration and delivers 480Y/277V secondary output with 175 kVA capacity, operating at 60Hz frequency with a temperature rise of 150°C and 220°C insulation class. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 41 inches high by 32 inches wide by 25.5 inches deep, and features mechanical lug secondary terminations with 3.5-6.5% impedance and 55 dBA sound level. It complies with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and is approved for installation in US and LATAM markets. Typical applications include industrial facilities, commercial buildings, and power distribution systems requiring reliable three-phase power transformation. Key Features & Specifications
