DESCRIBE

The ABB OTM63F4C12T380C is a 4‑pole automatic transfer switch (ATS) / motorized change‑over switch designed for automatic or remote switching of electrical loads between two independent three‑phase AC power sources (for example, utility mains and a backup generator). This device is part of ABB’s OTM series of compact automatic transfer switches intended for use in industrial, commercial, and critical power applications. It allows safe and reliable continuity of power by coordinating the transfer between source 1 and source 2 using a motor operator and control logic. The switch provides safe isolation and mechanical interlocking to prevent the paralleling of sources during transition.
