Hammond Power Solutions C1F1C5HRS - Transformer 1.5kVA 480/277V-277/208V

C1F1C5HRS

Hammond Power Solutions C1F1C5HRS is a general purpose transformer designed for industrial power distribution applications. This single-phase unit features a 1.5 kVA capacity with primary voltage inputs of 480V/277V and secondary outputs of 277V/208V, constructed with copper windings rated for 135°C temperature rise and 180°C insulation class. The transformer is housed in a Type 3R/IP24 rated enclosure with ANSI 61 grey finish, measuring 11.75 inches high by 7.06 inches wide by 6.25 inches deep, and operates at a quiet 45 dBA sound level. It complies with IBC 2018 seismic standards (Sds=2.0, z/h=1, lp=1.5) and meets NEMA ST-20 requirements, making it suitable for commercial buildings, industrial facilities, and HVAC systems requiring reliable voltage transformation.
