Design versions for 7 A devices:
For the 7 A device without clearance, a distinction is made between the following design
versions:
Design version
Individually with clearance a = 22.5 mm
Can be implemented with signal loop-through connectors when using device
connectors.
Note:
When using the 3-phase busbar systems, the necessary clearances can also be
implemented by leaving the connections free. Cover the free connections with cover
caps (accessories) to protect the free terminal lugs against touch.
7 A device alternately with 2 A device or 0.5 A device (b) without clearance
Devices with the same rated operational current without clearance: Side-by-side
Note
Please note the assembly examples in Chapter "Typical circuits (Page 167)".
Note
When using the 3-phase busbar system, you can achieve the necessary clearances by
leaving the connections free. Cover the free connections with cover caps (accessories). This
will protect the free terminal lugs against touch.
Note
If you are using fuse modules on 8US… busbars, you can achieve the necessary clearances
by installing cover profiles for 8US1922… busbars.
