Hammond Power Solutions C1F025LES - Transformer 25kVA 240x480V-120/240V

C1F025LES

Hammond Power Solutions C1F025LES is a single-phase general duty transformer designed for industrial power distribution applications. This 25 kVA unit features versatile voltage conversion with primary inputs of 240x480V and secondary outputs of 120/240V at 60Hz frequency, constructed with aluminum 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 27.38 inches high by 14.5 inches wide by 10.75 inches deep, and operates at a quiet 50 dBA sound level while meeting IBC 2018 seismic standards with Sds=2.0, z/h=1, and lp=1.5 parameters. Compliant with UL50 and NEMA ST-20 standards, this transformer is suitable for commercial buildings, industrial facilities, and equipment power supply applications requiring reliable voltage transformation with mechanical lug terminations and electrostatic shielding.
