The figures shown in the diagram refer to a minimal bar centre distance of 60 mm. Larger centreto-centre spacings are permissible. The rated
operating voltage depends on the choice of bar
centre distance and the configuration of the
system with top-mounting components. The
rated values can be taken from the technical
specifications for the components. Compliance
with the creepage distances and clearance to
DIN EN 60 664-1 should be checked in the final
assembly or final application.

Mounting distance of busbar claws:
In order to achieve the cited short-circuit protection,
the busbar claws must be fitted at a spacing of
300 mm. If there is a busbar support, a contact
maker or a longitudinal connector located within this
300 mm, there is no need to fit a claw at this point.

Short-circuit withstand strength to UL 508
The short-circuit withstand strength of RiLine
has been extensively tested. Short-circuit
withstand strength to UL criteria is assessed
via the root-mean-square value of the shortcircuit current (IRMS), which must be applied for
at least 3 periods (60 ms).
During the course of testing, the test equipment has been adjusted to the respective
root-mean-square values (IRMS). The resultant
peak short-circuit currents Ip are shown in the
diagrams below.
