Hammond Power Solutions TE3A0660KKM - 3-Phase Transformer 660 kVA (480D-480Y/277V)

TE3A0660KKM

Hammond Power Solutions TE3A0660KKM 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 660 kVA capacity, operating at 60Hz frequency with 150°C temperature rise and 220°C insulation class. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 64"H x 49"W x 39"D, and incorporates a single electrostatic shield with Dyn1 vector configuration. Compliance includes NRCAN 2019 efficiency standards and IBC 2018 seismic requirements (Sds=2.0, z/h=0, lp=1.5), with sound levels maintained at 62 dBA per NEMA ST-20. Typical applications include industrial facilities, commercial buildings, and utility power distribution systems requiring reliable three-phase power conversion. Key Features & Specifications
