Hammond Power Solutions SG3N0075LE - Single-Phase Transformer 75 kVA (Type 3R)

SG3N0075LE

Hammond Power Solutions SG3N0075LE is a single-phase general duty transformer designed for industrial power distribution applications. This 75 kVA unit features flexible primary voltage configurations of 240x480V with parallel/series connections and delivers secondary voltage of 120/240V, constructed with aluminum windings rated for 150°C temperature rise and 220°C insulation class. The transformer meets stringent efficiency standards including DOE 2016, NRCAN 2019, and NMX 2021, while housed in a Type 3R/IP24 enclosure with ANSI 61 grey finish measuring 36" H × 28.25" W × 27" D. It complies with IBC 2018 seismic requirements (Sds=2.0, z/h=1, lp=1.5) and operates at 50 dBA sound level, making it suitable for commercial buildings, industrial facilities, and utility applications requiring reliable power conversion with standard impedance range of 3% to 6.1%.
