Building installation with
N-conductor isolation
Special external cross-connections (WQB-
PEN) are available for neutral conductor
test-disconnect terminals (WNT).
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. This results earthed neutral
conductor with protection function in
three-phase systems. These
establish contact between the and PE
terminals. For terminal
