Schneider Electric EE30T3HBISCUNLP42DB Three-Phase Transformer

Schneider Electric's Square D EE30T3HBISCUNLP42DB is a 30 kVA dry-type transformer designed for indoor, three-phase service. It steps a 480 V delta primary down to a 208Y/120 V secondary, making it suitable for supplying 208/120 V loads from a higher-voltage 480 V distribution system in commercial and light-industrial facilities. This energy-efficient DOE 2016 model adheres to modern efficiency standards while providing reliable power for control panels, lighting, and small motors fed from a 480 V three-phase service. Rated for a 150°C rise with insulation class 17D and housed in a NEMA 2 enclosure, the unit is engineered for indoor environments with dust and moisture considerations. The 30 kVA rating delivers balanced three-phase performance, enabling compact installation in coordinated electrical rooms or panel boards without relying on oil-filled equipment. Typical applications include feed-through or sub-feed transformer configurations in commercial buildings, data centers, and manufacturing spaces where a stable 208/120 V auxiliary supply is required from a 480 V service.
