SIVACON 8PS system LX Flexible power distribution
up to 6300 A
SIVACON 8PS busbar trunking systems
High efficiency and through to flexible SIVACON power distribution for buildings and
industry from 800 A to 6300 A.
Greater cost-effectiveness
The system can be mounted in any position, thus offering easy and ideal planning
options. Various conductor configurations
enable safe and fast installation as well as
flexible expansion of the system LX, saving
both costs and time.
7
Increased safety
The system design offers protection
against adverse environmental conditions
as well as guaranteed protective conductor
protection due to the aluminum enclosure
and high short-circuit strength, thus guaranteeing continuous operational safety.
Highlights
7
Improved safety through type-tested
switchgear and controlgear assemblies
(TTA) according to IEC/EN 60439-1 and
IEC/EN 60439-2
7
Transport of high currents with low
voltage drop through the sandwich
construction
7
High protection in contaminated and
moist environments through IP55
7
Reliable fire protection through tested
fire barrier
7
Flexiblet through versatile conductor
configurations
7
High communication capability
