Siemens 3F3Y030K13 Three-Phase Power Transformer

Siemens 3F3Y030K13 is a 30 kVA three‑phase dry‑type transformer with a 480 V primary and a 208Y/120 V secondary, designed to step down three‑phase power for downstream equipment. The primary winding is 480 V (delta) and the secondary provides 208Y/120 V three‑phase output, making it well suited for panel boards, machines, and control gear in industrial facilities that require a stable 120/208 V supply. It belongs to Siemens’ 3F3Y K13 family, featuring indoor dry‑type construction and ventilated cooling for reliable operation in manufacturing environments. Rated for 60 Hz operation, this transformer offers a compact footprint and the appropriate power rating for moderate‑load distribution in electrical rooms or equipment rooms.
