A 75 kVA 480-208Y/120 volt 3 phase transformer is a commonly used low-voltage dry-type distribution transformer for commercial buildings, industrial facilities, data centers, manufacturing plants, and other electrical systems that require both 208V three-phase power and 120V single-phase power. This transformer steps down a 480V three-phase electrical supply to a 208Y/120V secondary system, making it possible to supply three-phase equipment while also providing 120V power for lighting, receptacles, controls, and other single-phase loads. For projects in the United States and Canada, common specifications include a 60 Hz frequency, 480V delta primary, 208Y/120V grounded-wye secondary, dry-type construction, and NEMA-rated enclosures.
