Circuit breaker communication: 3VA molded case circuit breakers

  • Entry
Molded case circuit breakers belong to the SENTRON product family of protection, switching, measuring and monitoring devices and can be used in applications between 25 A and 1600 A.

The molded case circuit breakers can be integrated via PROFINET and PROFIBUS directly into the TIA Portal  >  V14 and SIMATIC Energy Suite.

Integrated as standard in the COM800/COM100 breaker data server is an Ethernet interface with the Modbus TCP protocol to allow communication with powerconfig parameterization software and the powermanager energy management software.


The communication equipment for the molded case circuit breakers can be installed and connected 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 provides a cost-efficient communication interface for up to 8 3VA2 molded case circuit breakers.



The 3VA2 molded case circuit breaker utilizes a modern communication concept. This concept is based on the COM800 breaker data server, which can link up to eight molded case circuit breakers to different bus systems. The 3VA molded case circuit breakers set new standards in flexibility and the variety of modular accessories available.

  • The motor operator with stored energy operator (SEO520) supplements the portfolio of 3VA motor operators with a synchronizable remote operator with optional communication link.
  • Integrated communication concept together with the 3VA27, 3VA molded case circuit breakers and the 7KM PAC measuring devices. The communication function is available from 25 A to 1600 A (ACB 3WL10 from 630 A ... 1250 A)
  • The 3VA27 molded case circuit breakers can be equipped with an optional communication function. The Electronic Trip Units ETU650 or ETU660 support the communication function.


Communication/metering functions

The use of modern communication-capable 3VA2 molded case circuit breakers opens up completely new possibilities in terms of start-up, parameterization, diagnostics, maintenance and operation. This allows many different ways of reducing costs and improving productivity in industrial plants, buildings and infrastructure projects to be achieved.

  • Optional communication function: Support from ETU650 or ETU660 Electronic Trip Unit.
  • The communication modules support Modbus TCP and Modbus RTU.
  • The SEO520 is also optionally available with communication functionality. A connection with the COM060 communication module integrates it into the communication environment of the 3VA molded case circuit breakers and ensures that the molded case circuit breaker can now also be switched via the supported communication networks and the powerconfig and powermanager software packages.


Optional expansion modules enable flexible communication

With COM800/COM100, the 3VA2 molded case circuit breakers can be integrated into the relevant communication networks via the following optional expansion modules:

  • Switched Ethernet PROFINET
  • PROFIBUS
  • RS 485 (Modbus RTU)

Matching software

powermanager: The powermanager power monitoring software acquires all measured variables that are needed to optimize power consumption and so reduce costs.

powerconfig: The configuration software – integrated in the TIA Portal – offers a wide functional scope and is convenient to put into operation.
