DESCRIBE

The ABB OTM63F4C11D380C is a 4‑pole motorized automatic transfer switch (ATS)/motorized change‑over switch designed for automatic and manual switching of electrical loads between two separate AC power sources — typically the utility mains and a backup generator — in three‑phase low‑voltage distribution systems. It enables remote or automatic switching using a motor operator, and also allows local manual operation via a handle. A mechanical interlock ensures that both power sources are electrically isolated and cannot be connected simultaneously, enhancing safety and preventing back‑feeding. This type of switch is suitable for industrial, commercial, and critical power applications where reliable source transfer and continuity of power are essential.
