Building installation with
N-conductor isolation
Special external cross-connections (WQB-
PEN) are available for neutral conductor
test-disconnect terminals (WNT). PEN bridge joins separate PE
and conductors into one PEN conductor,
creating the transition from TN-S a
TN-C system.
Standard installation
Depending the terminal type, inside or
outside, PEN bridges are available for both
PE and conductor terminals from mm2
Important! For outside bridges, please
note that this context only the next
smaller rated cross-section (than standard)
can connected.PEN bridges
Accessories Specific functions and variations
Energy distribution for machines in
buildings usually consists 5-conductor
systems (TN-S). Order No. These
