Hammond Power Solutions DM330JHC - 3-Phase Transformer 330kVA (460D-400Y/231V)

DM330JHC

Hammond Power Solutions DM330JHC is a three-phase general duty transformer designed for industrial power distribution applications. The unit features a 460V delta primary configuration with 2x2.5% FCAN/FCBN taps and delivers 400Y/231V secondary voltage through a wye-N connection, rated at 330 kVA with 60Hz frequency operation. Constructed with a Type 3R/IP24 enclosure finished in ANSI 61 Grey measuring 51.5 inches high by 39.5 inches wide by 34 inches deep, the transformer maintains a 150°C temperature rise with 220°C insulation class and operates at 60 dBA sound levels. The unit complies with IBC 2018 seismic standards (Sds=2.0, z/h=0, lp=1.5) and carries approvals for installation in US and LATAM markets. Typical applications include industrial facilities, manufacturing plants, and commercial power systems requiring reliable three-phase power conversion with standard impedance ranges of 4.5% to 7%.
