The ABB OTM160E4C10D380C is a 4‑pole motorized automatic transfer switch (ATS) / change‑over switch used to automatically transfer electrical loads between two independent AC power sources (such as utility mains and backup generator) in industrial and commercial electrical distribution systems. It’s part of ABB’s OTM series of motorized change‑over switches featuring motorized remote operation as well as manual override, with built‑in safety mechanisms to prevent simultaneous connection of both power sources. These switches are suitable for applications that require reliable power continuity and safe switching in three‑phase networks
