1.3 Safety instructions
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens' products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the Internet if and to the extent such a connection is
necessary and only when appropriate security measures (e.g. firewalls and/or network
segmentation) are in place.
For additional information on industrial security measures that may be implemented, please

1.6 3WL10 / 3VA27 circuit breakers
1.6.1 System overview
In order to meet the requirements of modern power distribution, the 3WL10 / 3VA27
communication-capable air circuit breaker is modular in design and allows for the flexible
addition of functions as required.
The system is based on a reliable, microprocessor-controlled electronic trip unit, precise
measured value acquisition with an integrated voltage tap, in addition to support for the most
common bus systems for industry and infrastructure.

1.6.2 Software applications
Energy management with powermanager
Siemens offers the powermanager software application, which is designed for power and
plant monitoring applications. When used in conjunction with SENTRON protection devices
such as 3VA, 3WL, 3VL, and PAC as well as equipment supplied by third parties,
powermanager is a power monitoring system that reduces energy costs and increases the
availability of electrical supply and distribution systems.
powermanager acquires the measured variables that are needed to optimize power
consumption and so reduce costs. These variables not only include energy and power
values, but also electrical parameters such as current, voltage, or power factor. Not only is
this system able to display values, but also to monitor and archive them for later analysis. In
addition, the load monitoring function is capable of monitoring a specified setpoint and
making recommendations as to which loads should be connected and disconnected.

Communication 3WL10 Air Circuit Breakers & 3VA27 Molded Case Circuit Breakers
System Manual, 06/2019, L1V30499596021-01 11
Identifying cost-cutting potential
The power monitoring software has been tested by the TÜV Rheinland for its suitability to
support an energy management system in accordance with ISO 50001.
Functionality and user-friendliness
The salient features and functions of the power monitoring software are as follows:
● Good scalability
● Enhanced report templates
● Reaction plans
● Mass parameterization
● Virtual measuring points for computing customer-specific parameters
● Load monitoring function for monitoring specified power limits for freely definable time
periods
● Switching recommendations in the event of limit violations
● Remote control of circuit breakers
You can find more information on energy management with powermanager in the Internet
(https://new.siemens.com/global/en/products/energy/low-voltage/components/sentron-
measuring-devices-and-power-monitoring.html).
Commissioning and service
powerconfig is a commissioning and service software application for communication-capable
measuring devices and circuit breakers from the SENTRON product family. Its main
functions are as follows:
● powerconfig facilitates parameterization of the devices, resulting in considerable time
savings, particularly when several devices have to be set up.
● With powerconfig, the SENTRON circuit breakers and the 7KM and ATC measuring
devices can be parameterized, documented, operated, and analyzed using various
communication interfaces.
● powerconfig can be used to archive settings electronically and as printouts.

1.7 Individually configured circuit breakers
The 3WL10/3VA27 circuit breaker is manufactured according to individual system
requirements. To adapt a 3WL10/3VA27 circuit breaker to individual requirements, a
3WL10/3VA27 circuit breaker can be configured in the Internet.
Note
You can assemble your own 3WL10/3VA27 circuit breaker simply and quickly in the online
configurator and then generate an article number.

Overview
The COM043 module offers fast and simple integration in monitoring, maintenance, and
energy management systems as well as in industrial automation systems by way of the
Modbus TCP module.
Communication permits the continuous transfer of data, such as status and measured
values, from the 3WL10 / 3VA27 circuit breaker. Switching and reset commands can be
executed by means of simple operations.

In addition to the static IP address, the module also supports:
● DHCP
● AutoIP
In the 169.254.x.x range, where the 2 LSBs (.x.x, least significant bytes) of the IP address
are calculated on the basis of the device MAC address and are therefore identical
between consecutive operations.
