Communication Structure of the
WL Circuit Breakers
The following diagram:
• Provides an overview of the
different communication options
available with WL Circuit Breakers
and their modules.
• Illustrates the high level of
system flexibility, enabling new
and innovative ideas to be
implemented.
Starting at the lowest level with
simple configuration of the circuit
breakers, to the field level with
a PLC and WinPM.Net software
tool, to a connection to the
Intranet/Internet, the potential for
saving on power costs by means
of intelligent power management
is achievable.
The individual circuit breakers and
their modules are described in the
following chapters.
