400kva transformer 480v 208y 120v volts 240 volt 600

Description:

The 400 kVA transformer is a three-phase dry-type distribution transformer used in industrial power distribution systems to step down 480 V primary voltage to 208Y/120 V secondary voltage for supplying electrical equipment and facility loads. Commonly installed in manufacturing plants, commercial buildings, data centers, hospitals, water treatment facilities, and industrial electrical distribution systems requiring reliable three-phase power conversion. Maintenance teams and electrical contractors use this transformer for new installations, electrical infrastructure upgrades, and replacement to provide dependable power distribution and minimize system downtime.

Applications:

The 400 kVA transformer is designed to safely convert three-phase electrical power from a 480 V supply to a 208Y/120 V distribution system while providing electrical isolation and efficient power delivery. It is widely used in industrial automation facilities, commercial buildings, manufacturing equipment, HVAC systems, data centers, hospitals, and utility distribution networks where reliable voltage transformation and continuous power availability are essential.
