The flexible communication solution with the COM800 breaker data server
3VA2 molded case circuit breakers utilize an innovative, modern communication concept.
This concept is based on the COM800 breaker data server which can link up to eight 3VA2
molded case circuit breakers to different fieldbus systems.
The COM800 / COM100 breaker data servers (see below, section "The smart
communication solution with a COM100") provides an integrated Ethernet interface for
operation of the circuit breaker with powerconfig, powermanager, the DSP800 display and all
third-party systems which support the Ethernet (Modbus TCP) protocol.
If the Switched Ethernet PROFINET and PROFIBUS DPV 1 expansion modules are
installed, the 3VA2 molded case circuit breaker can be modularly integrated into the
PROFINET and PROFIBUS landscape of TIA (Totally Integrated Automation), i.e. of the
SIMATIC system.
The communication equipment for the molded case circuit breakers can be installed and
connected up extremely easily, reliably and efficiently thanks to the connector system used.
The 24 V DC supply to the electronic trip units is also reliably provided by these connections.
The COM800 breaker data server utilizes independent supplementary functions to deliver
valuable information about the connected molded case circuit breakers and the power
distribution system.
● Expansion of the tripping history on the basis of the scope, quantity and time stamps of
trip events
● Generation of minimum and maximum values
● Monitoring of limits for measured variables of the electronic trip units
● Power demand

Reference documents (Page 12)).
