PEN bridges
Energy distribution for machines or
in buildings usually consists of
5-conductor systems (TN-S). By
contrast, energy supply mains are
frequently rated as 4-conductor con-
nection. A PEN bridge is used to
split the joint PE and N conductor in-
to 2 separate conductors, trans-
forming the TN-S to a TN-C mains.
Standard installation
Depending on the terminal type, in-
side or outside PEN bridges are
available for both PE and N conduc-
tor terminals from 10 mm
2
.
Important! For outside bridges,
please note that in this context only
the next smaller rated cross-section
(than standard) can be connected.
Building installation
with N conductor isolation
There are special outside cross-con-
nectors (WQB-PEN) for isolating
neutral terminals (WNT) which estab-
lish the contact between NT and PE
terminals. This results in an earthed
neutral conductor with protection
function in three-phase systems.
