DESCRIBE

The ABB OTM32F4C12T380C is a 4‑pole automatic transfer switch (ATS) / motorized change‑over switch engineered to transfer electrical loads between two independent three‑phase AC power sources (such as utility mains and a backup generator). It belongs to ABB’s family of motorized change‑over switches, which are designed to provide reliable and safe power source switching with both automatic (motorized) and manual operation. These switches incorporate safety interlocks and robust construction to prevent simultaneous connection of both power sources and to ensure continuity of power in industrial and commercial installations. ABB’s motorized change‑over switches are compact, easy to install, and conform to relevant IEC standards for transfer and change‑over applications.
