The ABB OTM800E3C21D380C is a 4‑pole motorized automatic transfer switch (ATS) / change‑over switch designed to automatically transfer electrical loads between two independent AC power sources, such as utility mains and a backup generator, in three‑phase low‑voltage power distribution systems. This switch is part of ABB’s OTM series of motorized change‑over devices and is built for robust, high‑current applications. It supports motorized automatic operation and also allows manual override via a handle. A mechanical interlock ensures the two power sources remain isolated and cannot be connected simultaneously, enhancing safety during transfer events. The device is suitable for industrial, commercial, and critical‑power installations requiring high‑current source switching.
