Connection to non-Siemens distribution boards
Versions
The connection units for non-Siemens distribution boards are available in aluminium or
copper depending on the version. They are delivered without a joint block.
For type selection: See selection and ordering data (Page 56).
Connection options
Since the area of application refers to customized solutions, it is necessary to coordinate
early with the distribution board vendor.
The distribution board vendor is usually responsible for copper-plating the non-Siemens
busbar connection units with the distribution board busbars.
Rated currents
You can find the rated currents in the relevant Basic type code (Page 28). This information
applies in accordance with IEC/EN 60439-1 and -2 for an ambient temperature of 35 °C
averaged over 24 hours. The limit temperature of the copper busbars provided with a heat-
resistant insulation foil is 135 °C.
When using busbar connection units for non-Siemens distribution boards, you must ensure
that the limit temperature is not exceeded.
Connection cross-sections for copper-plating Dimension drawings (Page 159).
Short-circuit rating
The short-circuit rating of the busbar connection units for non-Siemens distribution boards
depends on the copper-plating in the distribution system. The short-circuit rating of the
busbar trunking systems can only be verified by the distribution board vendor. The busbar
connection unit for non-Siemens distribution boards is type-tested as delivered.
With regard to its strength, the copper-plating must be dimensioned to the required short-
circuit level.
