Small conductor cross-
sections
With conductor cross-sections that are
≤
1 mm
2
, you have to use an insula-
ting stop to ensure the conductors remain securely clamped.
The illustration below shows the procedure:

1.5.4 Connection cross-sections
Because SIRIUS is a modular system, the connection cross-sections are the
same for all devices of a single frame size.
The following tables specify the permissible conductor cross-sections for
main and auxiliary conductor connections:
Frame size S00
