Intelligent switchboard

SIMARIS control – digital intelligence for your SIVACON S8plus

Digitalization is becoming a key criterion for success in the process industry and in critical infrastructure. Important data for this comes from the electrical power distribution. Harness the full potential of your energy data – with SIMARIS control, the digital intelligence of your SIVACON S8plus.

SIMARIS control for more efficient and reliable workflows

  • Obtain operational diagnostics faster and more easily – based on your energy data
  • Define and check threshold values for supervision, control, and diagnostics more easily – transparency down to the individual feeder
  • Monitor operational data, such as switching rates and runtimes or temperatures, to plan maintenance predictively
  • Turn many individual devices into one integrated system – with SIMARIS control
  • Integrate your switchboard in your IT structure and in higher-level automation or cloud-based analysis systems

Digitalization in five basic steps

Safe power distribution

High level of safety for personnel and system for reliable operation

We never compromise on safety when it comes to our switchboards: safety is an integral part. Our switchboards are developed, manufactured, and tested in accordance with the specifications of IEC 61439-2 for power switchgear and controlgear assemblies. With the special arc fault protection concept of SIVACON S8plus, we even take it one step further.

When milliseconds count …

… the right decisions are required to provide optimal protection for personnel and switchboard. Minimize your risk and increase system availability:

  • Active and resettable arc fault protection system with optical sensors, current transformers, and evaluation units
  • Tested according to IEC/TR61641 with a system based on IEC TS 63107

Discover your advantages with the S8plus protection system

Safety as an integral part

  • Design verified according to IEC 61439-2 as part of the basic development of SIVACON S8plus through development-related tests
  • Routine testing according to IEC 61439-2 for each manufactured low-voltage switchboard prior to its delivery
  • Both verifications are a key part of the quality assurance process and a requirement for the CE marking in accordance with EU directives and regulations

Seismic upgrade with proven safety

For use in seismically critical locations, we supply our switchboards in vibration-resistant, earthquake-tested designs. The results of the tests are summarized and reported in three categories:

  • Functionality of the switchboard during an earthquake
  • Functionality of the switchboard after an earthquake
  • Stability

Certification for ships and offshore platforms

  • Certifications for use on ships and offshore platforms from renowned international classification societies (DNV GL, LR, ABS)
  • Protection against saline atmosphere with high humidity (risk of corrosion)
  • Protection against vibration load of the switchboard due to swells or the ship’s drive
Flexible switchboard

Already on target today for tomorrow

The flexibility of our switchboards begins with the planning and extends to efficient operation and service. They adapt to your requirements.

Ready for new challenges

Our switchboards enable the combination of different mounting designs in one cubicle. Flexible components, such as the space-saving withdrawable units, make it possible to easily replace or supplement functional units. Powerful motor management systems complement the range of products for flexible adaptation to special tasks.

Harness the benefits of intelligent SIVACON S8plus switchboard so you can also respond flexibly to the challenges of tomorrow. Thanks to SIMARIS control, the increased transparency with regard to power flows and switchboard or device states not only enables faster fault diagnostics and predictive maintenance, but also flexible operation.
