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.

Introduction
1.6 3WL10 / 3VA27 circuit breakers
10 System Manual, 04/2020, L1V30499596021-02
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.

2.1.5 IOM040 digital I/O module
The IOM040 digital I/O module provides two input and two output contacts for electrical
control and signaling of states, alarms, and tripping of the circuit breaker.
Default settings of the inputs and outputs can be selected via the ETU display. The settings
can be freely configured via the TD410/TD420 test and commissioning tools and the
powerconfig software.
The IOM040 digital I/O module does not come with default factory settings.

The IOM300 external digital I/O module is suitable for external mounting on a standard rail.
The IOM300 external digital I/O module is suitable for the ETUs of both the 6-series and the
3-series because it is connected directly to the CB1 and CB2 terminals of the auxiliary
conductor terminal system.
The settings can be freely configured via the TD410/TD420 test and commissioning tools

2.1.7 Position signaling switch communication (PSS - COM)
Via the communication link, the position signaling switch PSS - COM provides the signal
indicating whether the circuit breaker in the guide frame is inserted or removed.
Unlike the position signaling switch PSS, whose signals are available at the auxiliary
conductor terminal strip, the position signaling switch PSS - COM only signals two different
states:
●"INSERTED" breaker position (circuit breaker in the CONNECT position)
●"ISOLATED" breaker position (circuit breaker in the TEST or DISCONNECT position)
The PSS - COM position signaling switch is installed as standard if the withdrawable circuit
breaker is ordered for communication.
