The safe choice – Now made smarter: SENTRON circuit protection devices with measuring and communication function
PROTECTING AND MONITORING ELECTRIC CIRCUITS
Circuit protection devices such as miniature circuit breakers, arc fault detection devices or fuses are used for protecting lines or loads in electric circuits. In case of overload, short circuit or arcing faults, they disconnect the affected circuit from the network.
Measuring and communication capable 5SL6 COM miniature circuit breakers, 5SV6 COM AFDD/MCBs, 3NA COM LV HRC fuse links collect information on the switching status and faults in the circuit. With the 5ST3 COM auxiliary switches and fault signal contacts, standard 5SY, 5SP4 and 5SL miniature circuit breakers (MCBs) as well as 5SV3 and 5SU1/5SV1 residual current operated circuit breakers (RCBOs) can be expanded with little effort and small space requirement with measurement and communication functions. Communication capable devices can be connected wirelessly to the 7KN Powercenter 1000 data transceiver. This collects the measured values and transmits them for visualisation and evaluation to mobile devices, PCs or higherlevel IoT interfaces, making them available for cloud applications. Transparency and system safety are enhanced.
GENERATING VALUABLE DATA IN THE CIRCUIT – QUICKLY AND EASILY
Thanks to the possibility of retrofitting, the communication-capable 3NA COM LV HRC fuse link offers you a particularly simple and uncomplicated way of integrating digitization in transformer substations. Despite of its additional metering and communication capabilities, it features the same dimensions as the conventional LV HRC fuses and can simply be installed in their place in existing 400 V power distribution systems.

The measured data is transmitted wirelessly within a field to the 7KN Powercenter 1000 data transceiver without requiring any further cabling and, from there, the data can be forwarded to higher-level gateways or monitoring and analysis systems via Modbus TCP. Its application in switchgear also opens up new possibilities for creating transparency in power distribution and increasing system availability in view of today’s increased requirements.
BUNDLING AND FORWARDING MEASURED VALUES
7KN Powercenter 1000 data transceivers collect the data for communication and measurement capable 5SL6 COM MCBs, 5SV6 COM AFDD/MCBs, 5ST3 COM auxiliary switches and fault signal contacts (AS+FC). They communicate wirelessly within a power distribution board or distribution board, each with up to 24 circuit protection devices. The measured values are saved for a period of up to 30 days in the 7KN Powercenter 1000. The data can be accessed via Bluetooth with mobile devices on-site or transmitted to higher-level systems by means of Modbus TCP. With the SENTRON powermanager power monitoring system, energy flows, for example, can be visualized and optimized. Via the 7KN Powercenter 3000 IoT data platform or the LOGO! 8.3 logic module, the recorded data can be viewed directly on a web server or transferred to Cloud applications and evaluated.

SENTRON POWERMIND / 7KN POWERCENTER 3000
Intelligent cloud solutions for energy data
With the new Sentron powermind cloud app, energy data in buildings, infrastructure, and industrial plants can be monitored and analyzed right in MindSphere.
Users see a real-time overview of current energy consumption and trends over time, both for entire systems and as individual electrical loads. Using this information, companies can derive optimization measures to reduce their energy consumption, costs, and CO2 emissions. With the help of the 7KN Powercenter 3000 IoT data platform, energy data can be centrally collected and individually transferred directly to MindSphere.
Corresponding cloud applications enable comprehensive, cross-location analyses that make it possible to access the energy distribution system and all values and statistics at any time and from any location. Control and preventive maintenance can also be per- formed remotely. Warning indicators allow users to respond to faults immediately and to quickly and easily locate errors.
