Square D 10S67F Industrial Control Transformer

Square D 10S67F is a dry-sealed, general-purpose multi-tap control transformer rated at 10 kVA, designed to furnish 110/120 VAC control power from higher-voltage mains in industrial panels. It features dual primary windings configured for 190/200/208/220 V input to 380/400/416/440 V and a 110/120 VAC secondary, operates at 50/60 Hz, and is a 1‑phase device. Encased in a rugged steel NEMA 3R enclosure for wall mounting, its dimensions are approximately 11-3/4 in L × 9-3/4 in W × 14-3/4 in H, with a temperature rise rating of 115 C. As an export-model transformer from Square D (Schneider Electric), the 10S67F is commonly used to power low-voltage control circuits in industrial equipment from higher-voltage primary supplies, offering a compact 10 kVA solution for control panels requiring a stable 110/120 VAC output from 208–440 VAC services.
