Modular benefits

The coupling set power infeed towards the roof section is always based on the same riser at the side. It is always identical, regardless of whether it is integrated into a coupling section or accommodated in another enclosure as a separate section.
fri190402300_1920x945

Coupling section

TO MAINTAIN FAIL-SAFE OPERATION

A combination of an air circuit-breaker section with a busbar riser optionally arranged on the left or right.

 

  • Individual sections of busbar can be de-energised without switching off the entire system, to prevent malfunctions and total failures.

  • With the VX25 Ri4Power, busbar sections may be safely disconnected thanks to comprehensive, stable partitioning, which allows the stringent requirements for overall short-circuit resistance to be reduced.

  • Similar layout as with the air circuit-breaker section. The system synergies help to significantly reduce assembly time and offer major cost-saving potential.

Universal benefit

One single section type is sufficient for all horizontal fuse-switch-disconnector types.
