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.

for maximum demands

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.

Connection to energy management, control, and automation systems

Reduce energy costs, increase plant availability
For industrial plants to operate efficiently, their load must be constantly optimized and downtime reduced. The 7KT/7KM PAC measuring devices and communication capable 3WL/3VL/3VA circuit breakers integrated in the power distribution board can help you achieve this.
They record precise and reliable energy values for electric feeders or individual loads because only by knowing your energy consumption can you reduce energy costs. For the further processing of measured data, additional devices can easily be integrated into higher-level automation and energy management systems, thanks to the wide variety
of communication options they offer. The communication- capable devices supply important measured values via standardized bus systems for the purpose of assessing the system status and power quality.
