DESCRIBE

The ABB OTM100F4C10D380C is a 4‑pole motorized automatic transfer switch (ATS) / change‑over switch designed to automatically and manually transfer AC electrical loads between two independent power sources — typically the utility (mains) supply and a backup generator — in three‑phase low‑voltage distribution systems. It integrates a motorized operator for automatic switching based on control logic and supports manual override via a handle for maintenance or emergency use. The switch is engineered with mechanical interlocks that prevent the two sources from being connected simultaneously, improving safety and protecting connected equipment. It is suitable for use in commercial, industrial, and critical‑power applications where reliable continuity of supply is essential.
