Function
The 3KC0 transfer switching equipment is used in power supply networks for load transfers
between the normal power source and an alternative power source with an interrupted
supply at current ratings up to 1600 A. Switchovers are performed manually.
The 3KC0 can be used for switching between two main sources, one main source and one
generator, or between two generators. It is possible to use the 3KC0 as transfer switching
equipment for switching between two sources in compliance with IEC 60947-6-1. It is also
possible to use the 3KC0 as a load transfer switch for switching between two loads in
compliance with IEC 60947-3.
