Communication and system integration
4.8.1
Communication-capable 3VA UL molded case circuit breakers are presented in this chapter.
You will learn which components the 3VA UL molded case circuit breakers need for
communication, how these components are assembled and what properties they have.
Optimum integration of the 3VA UL molded case circuit breakers in a software and
communication system yields the following advantages:
● Acquisition of breaker status
● Remote parameterization
● Monitoring of capacity utilization
● Acquisition of consumption and performance data
● Local signaling via the EFB300 external function box
● Local visualization of the 3VA UL molded case circuit breakers
To make use of all these functions, a COM060 communication module must be installed in
the respective 3VA UL molded case circuit breaker and connected to a COM800 breaker
data server for up to eight 3VA UL molded case circuit breakers or a COM100 breaker data
server for a single 3VA UL molded case circuit breaker.
You can find detailed information on the communication module and breaker data server and
the communication link of the molded case circuit breaker in the 3VA Communication
System Manual (https://support.industry.siemens.com/cs/ww/en/view/98746267
).
Communication system of the 3VA UL molded case circuit breaker

communication system:
● Electronic trip unit (ETU)
● COM800 / COM100 breaker data server
● Optional expansion modules for three other communication networks
● COM060 communication module
● Draw-out unit with communication link
● EFB300 external function box (EFB)
● DSP800 display
● Commissioning and service software: powerconfig
