Tailor-made for the highest demands

SIVACON S8 low-voltage switchboard: safe, flexible and efficient.


A safe power distribution that can be adjusted

Whether in industrial plants, in buildings or in the infrastructure: Even a small disruption in the energy supply can have serious consequences - not only for the operation of industry or buildings, but above all for people. The highest demands should therefore rightly be placed on the security of power distribution.


Coordinated and compliant with standards: Systematic power distribution

Planung, Ausführung und Betrieb der Energieverteilung lassen sich mit unseren Produkten und Systemen sicher, flexibel und effizient realisieren. Die Niederspannungs-Schaltanlage SIVACON S8 und die SENTRON Komponenten sind perfekt aufeinander abgestimmt und geprüft. Dadurch werden nicht nur Investitionskosten und -risiken spürbar gesenkt, auch die Anlagenverfügbarkeit erhöht sich – und zwar während des gesamten Nutzungszeitraums.


Normkonform: IEC 61439

Since 2014, all low-voltage switchgear assemblies in the European Economic Area have had to comply with the IEC 61439 standard.

Compared to the old IEC 60439 standard, IEC 61439 describes clear areas of responsibility - divided into the tasks of an »original manufacturer« and those of a »manufacturer of a switchgear assembly«. The "original manufacturer" (e.g. Siemens) is the company that carried out the original design and associated verification of the switchgear assembly according to the relevant switchgear assembly standard.

With the SIVACON S8 low-voltage switchboard, customers are always on the safe side: It has a design verification according to IEC 61439-1/2.


BT-Anlagenbau uses the system that sets new standards in power distribution for industrial applications: SIEMENS Sivacon S8. Advantages of the system: minimized downtimes with simultaneous optimized utilization, adaptable and expandable thanks to the modular system structure.


SIVACON S8: for the highest demands

Safe down to the last detail
The SIVACON S8 low-voltage switchboard ensures a high level of safety for people and the system. The continuous testing according to IEC 61641 or VDE 0660 Part 500-2 guarantees safety in the event of an arc fault. Many well thought-out details such as a reduced use of plastic parts or the insulated main busbar ensure a high level of safety and system availability. The liability risk is therefore low.

Flexible and adaptable
Thanks to its modular component concept and a wide variety of parts, the SIVACON S8 low-voltage switchboard can be used to meet all individual requirements. The vertical field distribution busbars, for example, enable taps in the smallest grids thanks to their design as profile busbars or flat copper. Furthermore, the carriers of the switching devices have a modular design and can be staggered in depth.

Efficient throughout the process
More than 320,000 switch panels have already been brought onto the market by SIVACON Technology Partners. This shows that technologically demanding solutions can be efficiently implemented with the SIVACON S8 low-voltage switchboard. With the SIMARIS software tools, power distribution is easy to plan and the distributor can be configured quickly: The result is time savings and planning security throughout the entire process.

To use
  • The focus is on maximum safety for people and the system
  • The modular building block concept and high variety of parts ensure flexibility in construction
  • Technologically demanding solutions can be implemented efficiently




Whether in industrial applications or in infrastructure –

Connection to energy management, control or automation systems

Reduce energy costs, increase system availability

In order for industrial plants to run economically, their utilization must be continuously optimized and downtimes reduced. The 7KT/7KM PAC measuring devices that can be integrated into the switchgear and the communication-capable 3WL/3VL/3VA circuit breakers provide support here.


They precisely and reliably record energy values ​​for electrical outlets or individual consumers. Because only those who know the power consumption can reduce the energy costs. Thanks to their wide range of communication options, the devices can be easily integrated into higher-level automation and energy management systems for further processing of the measurement data. The communication-capable devices supply important measured values ​​via standardized bus systems for assessing the system status and the network quality.

  • Transparency of system states and preventive error avoidance
  • Increase system availability
  • Identify potential savings through transparency of energy flows
    reduce energy costs
