WL Communication-capable Circuit Breaker
WL Selection and Application Guide • 2005
WL Circuit Breaker
Connection Diagram
• Industry standard MODBUS
or PROFIBUS communication
available on all WL breakers
from 200A to 5000A.
• The high modularity of
the WL Circuit Breakers
and accessories allows
simple retrofitting of all
communication components.
• The ability to connect
additional input and output
modules to the breaker-
internal CubicleBUS of the
WL opens up a range of
opportunities to reduce
secondary device count
and wiring and to increase
functionality implemented
in switchgear.
• Innovative software
products for local
configuration, operation,
monitoring and diagnostics
of WL Circuit Breakers using
MODBUS, PROFIBUS or via
Ethernet/Intranet/Internet.
• Complete integration
of WL Circuit Breakers in
all Totally Integrated Power
and Totally Integrated
Automation Solutions.
