3KC transfer switching equipment safely switch between two power sources and ensure continuous power supply if one power supply source fails. These devices can also switch between two loads and prevent operational failures. In addition to the automatic transfer switching equipment (3KC ATSE), a remote-controlled variant 3KC RTSE as well as a manually operated version 3KC MTSE are also available. The 3KC MTSE is suited for manual transfer switching operations up to 1,600 A between two grids or two electrical loads, and can be mechanically interlocked. Used in industrial and infrastructure applications, all of these transfer switching devices fulfill the requirements according to the IEC 60947-6-1 and IEC 60947-3 standards.
