Planning with SIVACON 8 PS - Siemens

Planning with LDA/LDC4.2 System components4.2.10 Coupling unitsCoupling units are used if devices or sections of the power supply need to be disconnectedor connected accordingly. To adapt the busbar trunking system to the actual load, the busbarcross section can be reduced and protected against short circuits and overloads with acoupling unit.Coupling units can be fitted with switch disconnectors or circuit-breakers as appropriate fortheir application. Coupling units resistant to accidental arcs can be supplied as an option.Figure 4-8Coupling unitsRated currentsRated currents adapted to the systems between 1100 and 3000 A can be supplied asappropriate for the application.Operator controlThe coupling units can be operated using a handle or even a motor drive.DimensionsThe installation length in the busbar trunking run is 1600 mm.The maximum dimensions are 1320 mm x 450 mm x 750 mm (W x H x D).Planning with SIVACON 8 PS120 Planning Manual, 10/2007, A5E01541101-01
