The ABB OTM63F4C10D380C is a dual power transfer switch (change‑over switch) designed for automatic or motorized switching of electrical loads between two asynchronous power sources (e.g., utility mains and backup generator) in a three‑phase electrical system. It enables reliable continuity of power by providing a mechanism to transfer the load safely between source 1 and source 2, with built‑in isolation and switching functions according to IEC electrical standards. This kind of transfer switch is commonly used in industrial, commercial, and critical power installations where uninterrupted power is essential.
