The ABB DPT/SE 630 is a dual‑power automatic transfer switch (ATS) / change‑over switch designed for automatic or manual transfer of electrical loads between two independent power sources (such as utility mains and a backup generator) in three‑phase electrical systems. It is rated at 630 A to handle medium to high power loads in industrial, commercial, and infrastructure applications. This ATS ensures continuity of power supply by detecting loss or abnormal conditions on the primary source and transferring the load to an alternate source with safety interlocks to prevent both sources from being connected simultaneously. Models in this class are typically compliant with IEC standards and suitable for panel or enclosure mounting in power distribution systems.

The ABB OTM200E4CM230C is a motorized change‑over and transfer switch designed for automatic or remote switching of electrical loads between two independent AC power sources (such as utility mains and a backup generator) in three‑phase electrical distribution systems.
