Sivacon s8 - Safety Highlights

The SIVACON S8 low-voltage power distribution board ensures a high level of personal and plant
safety – at all times and everywhere.


• Design verification by verification test in accordance
with IEC 61439-1/-2
• Design-verified connection to the SIVACON 8PS busbar
trunking system


High level of personal safety thanks to
roof plate with pressure relief


Comprehensive certifications
• High degree of test coverage
• Certifications for use on ships and offshore platforms
• Earthquake upgrade


The patented locking system or simple or central
locking keeps doors closed even in the event of an
arcing fault.


Safety in the event of an arcing fault, thanks to testing in accordance with IEC 61641 and VDE 0660 Part 500-2: restriction of the effects of the arcing fault
• Within the power distribution board
• To a section
• To a compartment


An arcing fault barrier restricts the effects to one
section when an arcing fault occurs.


The insulated main busbars prevent the occurrence
of arcing.


Safe housing
• Frame made from stable sheet-steel profiles
• Aluzinc surfaces

Sivacon s8 - Flexibility Highlights

Thanks to its modular concept and wide variety of parts, SIVACON S8 can meet the most demanding requirements and satisfy all individual needs.


A variety of connection options via vertical section
flexible layout and optional expansions


Supply unit and feeder
• Via cable or SIVACON 8PS busbar trunking system from 630 to 6,300 A
• From the top or bottom
• Aluminum or copper busbar trunking system


The section can be installed – either single- or doublefronted
together with a main busbar system or
back-to-back with a separate main busbar system.


The standardized, circumferential rows of holes in the
sheet-steel profiles allow for individual expansion.


High level of flexibility thanks to innovative modular

• Different installation designs can be combined in
one section
• Functional units are easy to exchange or add


The functional compartments can be divided as required
with add-on modules.


Depending on requirements, different degrees of
protection can be implemented with the roof plate –
ventilated or non-ventilated.


The universal door hinge allows the hinge side to be
easily changed.

Sivacon s8 - Efficiency Highlights

The SIVACON S8 low-voltage power distribution board permits the efficient implementation of technologically
sophisticated solutions. The proof: Over 404,000 switching boards have already been installed in a wide
variety of applications by SIVACON Technology Partners.


Economical design
• Circuit breaker section provides enough space for up to three
circuit breakers
• Flexible installation design:
fixed-mounted or withdrawable design for easy maintenance


Efficient, flexible operation
• High packing density with up to 35 outgoing feeders
per section
• Fast exchange under operating conditions


Reduced service time thanks to maintenance-free
section connections


The patented ventilation slots reduce maintenance

• Cleaning is possible with the door closed and from the outside
• Low repair costs


The patented connection terminals are safe, flexible,
and easy to connect – during installation and in the
event of subsequent changes.


Reliable partners
• Maximum technological progress through constant innovation
guarantees the highest quality
• Brand strength combined with expertise gained over many years
and the availability of a local partner on-site


The SIMARIS software tools save time throughout the
process – from planning to configuration all the way to
plant documentation.


The innovative, communication-capable SENTRON
components are easy to integrate
• System status and energy flows are made transparent
• For energy-efficient plant operation
