Introduction and Overview

WL Circuit Breaker

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 achieveable.

The individual circuit breakers and their modules are described in the following chapters.

*The Siemens BDA Plus or meters, 9330, 9350, 95/9600 can be used as a gateway to enable Ethernet communication to the WL Circuit Breaker.

The 9500 meter can also be used as a central display unit for multiple WL breakers with metering capability.
