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.
