Hammond Power Solutions C1F007HRS - Transformer 7.5kVA 480/277V-277/208V Aluminum

C1F007HRS

Hammond Power Solutions C1F007HRS is a general duty transformer designed for industrial power distribution applications. This single-phase unit features primary voltages of 480/277V and secondary voltages of 277/208V with a 7.5 kVA capacity operating at 50/60 Hz frequency. The transformer is constructed with aluminum windings and housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 20.88 inches high by 12.25 inches wide by 9.25 inches deep. It complies with IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5) and features a 135°C temperature rise with 180°C insulation class. Typical applications include commercial and industrial power systems requiring reliable voltage transformation with 45 dBA sound level operation and 1-5% impedance characteristics.
