Communication planning 
Planning 
With the circuit breaker and the electronic trip units of the 6-series, Siemens low-voltage 
products offer an integrated communication concept together with the 3VA molded case 
circuit breakers and the 7KM PAC measuring devices. 
Features: 
●  The high level of modularity of circuit breakers and accessories allows easy retrofitting of 
all communication components 
●  Up to two communication modules can be used at the same time. 
●  Simple integration into power monitoring systems with the modular metering functions 
MF Basic or MF Advanced according to IEC 61557-1 
●  Simple integration into plant monitoring systems for monitoring 
–  Status 
–  Measured values 
–  Alarms and warnings 
–  Diagnostics 
–  Maintenance 
●  Significant additional benefits for the switchboard due to the possibility of connecting 
external input and output modules to the 3WL10 air circuit breaker 
●  Innovative software products for commissioning, testing, parameterization, operation, 
monitoring, documentation, and diagnostics of circuit breakers on site at the display, via 
the front interface using test devices or communication modules 
●  Integration of the circuit breakers into the Totally Integrated Power (TIP) and Totally 
Integrated Automation (TIA) solutions
