SIVACON S8 is setting new standards as a power distribution board or motor control center (MCC) for industrial applications or in infrastructure. And thanks to its modular design, SIVACON S8 can be optimally adapted to meet every requirement. A high level of safety, a state-of-the-art design and SIMARIS control functions are combined in this highly efficient switchboard.
Profit from benefits of the SIVACON S8 low-voltage switchboard – and the SIVACON S8plus feature package. Prepare your power distribution system for the digitalized future, and benefit from the numerous advantages:
Economical operation, minimal downtimes and optimized capacity utilization: You can count on standard-compliant power management. Compliance with the energy efficiency requirements defined in standard IEC 60364-8-1 ensures cost-effectiveness, while fulfillment of ISO 50001 requirements expands this scope to encompass compliance during operation, providing support with a specific process description when an operational energy management system is introduced.
The connection to energy management and automation systems as well as cloud-based analysis systems such as MindSphere supports reliable and future-oriented operation. With SIVACON S8, you are optimally equipped to accommodate the growing level of digitalization and increasing demands that future advances will hold.
Objective: Integration in existing IT structures
Benefits: Future-oriented switchboard diagnostics station = Uniform interface to higher-level automation and energy management systems and to cloud-based analysis systems
Actuators: SIMARIS control
Save costs and reliably safeguard ongoing operations: A first important step is to maintain a good overview of the status of the installed equipment and the transparency of power flows and electrical variables. Communication-capable protection, switching, measuring and control devices measure and record the energy values for feeders and individual consumer loads precisely and reliably. They also deliver important data via standardized bus systems, enabling assessment of the switchboard condition and network quality.
You can rely on the further advantages offered by SIVACON S8: molded case circuit breakers in withdrawable design, fully redundant communication system solutions, and data concentrators that convert all data into a single intelligent electronic device (IED) node. Sensors enable consistent, end-to-end temperature monitoring around the clock.
SIMARIS control is the optimum solution for comprehensive yet neatly arranged and clear representation of data and information. You benefit from convenient local visualization and control of the installed communication-capable switching devices – always up to date and centrally recorded for the entire switchboard. Various bus systems can be integrated in SIMARIS control, while a standardized data model enables uniform visualization of data. SIMARIS control thus clearly displays all the information delivered by the communication-capable switching, protection, and measuring devices used in SIVACON S8 in a structured, needs-oriented format.
From commissioning to regular ongoing operation: The practical local controls and the digital twin ensure maximum flexibility:
Quick and simple operational diagnostics: SIMARIS control ensures early provision of all necessary information, making it possible to reduce downtimes while supporting analysis and optimization of power demand.
SIVACON S8 stands for high level of safety. This low-voltage switchboard is a low-voltage power switchgear assembly design verified to IEC 61439-2 requirements. Its physical properties have been proven in test-bed runs under normal operational conditions as well as fault scenarios.
Optimum personnel safety is furthermore ensured by verification testing under arcing conditions to IEC/TR 61641 requirements. SIVACON S8 even exceeds the standards' requirements, offering for instance an even higher level of safety for operating personnel and operations with its active protection system against internal arcing. The efficient and redundantly-configured ventilation system also contributes to ensuring safe and reliable operation.
The new active protection system against internal arcing of the SIVACON S8 switchboard extinguishes arcs quickly and reliably. The system limits arcing time while significantly reducing the pressure wave and temperature. This added protection significantly reduces the danger of injury during operation and maintenance while preventing damage to the switchboard itself.
SIVACON S8 offers patented forced cooling technology for cubicles in circuit-breaker design and in universal mounting design, such as motor control centers (MCC). The system was designed and optimized by computational fluid dynamics (CFD) simulation, and was confirmed by numerous design verifications to IEC 61439 requirements.
The system reduces derating and provides a low temperature profile inside MCCs aimed at ensuring that the sensitive electronic equipment operates safely over a long service life. The control system monitors the temperature at critical spots and ensures energy-efficient cooling at all times. All fans are speed-monitored to enhance service life. The system has been redundantly designed for this purpose.
The circuit-breaker design offers optimal connection conditions in the cable or busbar connection compartment for every size of unit. There, cables or SIVACON 8PS busbar trunking systems can be connected via design verified connections.
The SIVACON S8 switchboard is available in a seismically tested version for meeting seismic design requirements. Testing includes functionality and stability tests both during and after an earthquake.
SIVACON S8 switchboards are well equipped for any use – even for applications onboard ships and offshore platforms. Conditions on the high seas pose particularly demanding challenges for switchboards, due not only to the salty and highly humid atmosphere, but also and in particular to the high mechanical stresses they are subjected to in these environments. SIVACON S8 switchboards have been certified to the standards required for such applications by a number of renowned international classification societies.
SIVACON S8 offers intelligent solutions that adapt to your specific needs and requirements. Different mounting designs can be easily combined within a single cubicle, and flexible modules make it easy to exchange or add functional units.
The SIVACON S8 are subject to a continuous innovation, ensuring the overall system will continue to technically advance. Compact, small withdrawable units enable space-optimized use, while powerful motor management systems offer the optimum solutions for your applications.
Whether small withdrawable units or normal withdrawable units: Optimally fitted withdrawable unit sizes allow the switchboard size to be minimized. With small withdrawable units of size 1/4 (up to four withdrawable units per compartment) and 1/2 (up to two withdrawable units per compartment) as well as with normal withdrawable units with heights starting from 100 mm, very high packing densities can be achieved with up to 48 withdrawable units per cubicle for space-optimized installation.
The space-saving design of the 300-mm-high small withdrawable units contribute substantially to this packing density, thereby reducing investment costs as well. The 300-mm-high small withdrawable units are especially suitable for the new Siemens SIRIUS and SENTRON device ranges, offering an optimized air-flow design to lower the temperature rise caused by the devices power loss. What's more, better access to the devices on the mounting plate ensures easy maintenance.
If there is little space available, the universal mounting design offers a safe, flexible, and cost-efficient solution. It allows various mounting designs – withdrawable, fixed-mounted with compartment doors, and plug-in design – to be combined within a single cubicle. A version in withdrawable design is the ideal solution for motor control centers in industrial plant applications requiring high availability of feeders and quick adjustment of the power supply system.
