Schneider Electric 30T6H Insulated Transformer

Schneider Electric's 30T6H insulated transformer is a 30 kVA, three‑phase dry‑type distribution transformer with a 480 V delta primary and a 240 V delta secondary, designed for indoor industrial power networks. It is part of Square D/Schneider Electric’s DOE 2016 energy‑efficient EXN/EE family; the EXN30T6H variant carries the DOE 2016 energy‑efficiency designation and aluminum windings paired with a 220°C insulation system intended to support a 150°C rise at full load, while a 120 V center‑tapped version (EXN30T6HCT) is available for 120/240 V service. Typical weight is around 260 lb, and the unit is commonly used to feed 240 V loads or 120/240 V control circuits from a 480 V supply in panel boards, motor control centers, and other distribution feeders.
