SIVACON S8
Low Voltage Switchgear
Safe and flexible power distribution

In industrial plants, buildings, and infrastructure, even a small disturbance in the power supply can cause serious damage – not only to industrial and building operations but also to people. That is why the standards for safe power distribution are so high.


In addition, today’s increasingly automated and digitized production processes and buildings require increasingly adaptable power distribution. They need a flexible layout, high availability, and personal and plant safety.

Conforming to standards: systematic power distribution

Our products and systems support the safe, flexible, and efficient implementation of power distribution planning, design, and operation. The SIVACON S8 low-voltage power distribution boards and SENTRON components are triedand- true and perfectly compatible.

This not only helps to significantly reduce investment costs and risks: It also increases plant availability throughout the entire period of use.

Conforming to standards: IEC 61439

As of 2014, all low-voltage switchgear and control gear assemblies in the European Economic Area must conform to the IEC 61439 standard. This standard describes distinct areas of responsibility. Specifically, it divides the tasks between an “original manufacturer“ and a “manufacturer of a switchgear and control gear assembly“. The original manufacturer (such as Siemens) is the company responsible for the original design and the associated verification of the switchgear and control gear assembly in accordance with the relevant standard.

With a SIVACON S8 low-voltage power distribution board, customers are always
on the safe side: It is design-verified according to the IEC 61439-1/-2 standard.
In addition, it disposes of the shipping approvals according to LR, DNV-GL and ABS.

SIVACON S8 
for maximum demands

Your benefit

  • Emphasis on maximum personal and plant safety

  • Flexible layout thanks to a modular concept and wide variety of parts

  • Efficient implementa- tion of technologically sophisticated solutions

Safe down to the last detail

The SIVACON S8 low-voltage power distribu- tion board ensures a high level of personal and plant safety. Continuous testing to
IEC 61641 and VDE 0660 Part 500-2 guaran- tees safety in the event of an arcing fault. Many well-thought-out details, including a reduced use of plastic parts and insulated main busbars, guarantee maximum safety and plant availability, resulting in low liabil- ity risk.

Flexible and adaptable

Thanks to its modular concept and wide variety of components, the SIVACON S8 low- voltage power distribution board can meet all individual requirements. For instance, the profile bar or flat copper design of the vertical section busbars allows for tap-offs in the smallest of grids. The switching device holders are also modular, with a graduated depth.

Efficient throughout the entire process

Over 320,000 switching boards have already been launched on the market by SIVACON Technology Partners – proof that technol- ogically sophisticated solutions can be effi- ciently implemented with the SIVACON S8 low-voltage power distribution board. Power distribution is easy to plan, and the distribu- tion board can be quickly configured using the SIMARIS software tools. The result: time savings and planning reliability throughout the entire process.

Analyze data, reduce energy costs, increase plant availability

For industrial plants to operate efficiently, their load must be constantly optimized and downtime reduced. The 7KM/7KT PAC measuring devices and communication- capable 3WA/3VA circuit breakers integrated in the power distribution board can help you achieve this.

They precisely and reliably record energy values for electric feeders or individual loads and display the values on-site. The communication-capable devices supply important measured values via standardized bus systems for the purpose of assessing the system status and power quality.
