Schneider Electric's Square D 225T3HFISNLP is a 225 kVA, three-phase dry-type transformer with a 480 V delta primary and a 208Y/120 V secondary, designed to step down higher-voltage distribution to 120/208 V circuits in commercial and light-industrial settings. It features aluminum windings, insulation rated for 115°C, and DOE 2016 energy-efficiency performance. This transformer provides a reliable source for feeding 120/208 V loads from a 480 V supply, enabling distribution to panel boards, lighting, and auxiliary equipment with a single compact unit.
