Schneider Electric 15T85HIS Transformer

Schneider Electric's Square D 15T85HIS is a 15 kVA three‑phase, dry‑type transformer that accepts a 208 V three‑phase input and provides a 208Y/120 V secondary. The unit is part of Square D's 15T85HIS family and is designed for distribution and control applications where a compact, air‑cooled transformer is required. With a 15 kVA rating, 208 V primary, and 208Y/120 V secondary, it is suitable for feeding 120 V circuits from a 208 V three‑phase service in commercial or light industrial installations. As a dry‑type transformer, it uses solid insulation and is compatible with standard Square D distribution equipment for panelboards and motor‑control centers. Typical applications include supplying 120 V loads in 208 V three‑phase systems, control circuits, lighting, and other equipment that require a 120 V output derived from a 208 V three‑phase source, all while maintaining three‑phase balance.
