breaker capable of communication.
Communication system architecture for 3VA
The central components of communication-capable 3VA molded case circuit breakers are
the ETUs 5-series or 8-series.
You can find additional information in the 3VA Communication System Manual. There the
components are regarded only as suppliers of information or receivers of commands.
Typical communication partners are:
●
SIMATIC S7
●
powermanager
While reference is frequently made to these systems, they are not an integral part of the 3VA
communication system.
