What are the advantages of current limitation?

The use of current-limiting CBs affords numerous advantages:

  • Better conservation of installation networks: current-limiting CBs strongly attenuate all harmful effects associated with short-circuit currents
  • Reduction of thermal effects: Conductors (and therefore insulation) heating is significantly reduced, so that the life of cables is correspondingly increased
  • Reduction of mechanical effects: forces due to electromagnetic repulsion are lower, with less risk of deformation and possible rupture, excessive burning of contacts, etc.
  • Reduction of electromagnetic-interference effects: Less influence on measuring instruments and associated circuits, telecommunication systems, etc.

These circuit-breakers therefore contribute towards an improved exploitation of:

  • Cables and wiring
  • Prefabricated cable-trunking systems
  • Switchgear, thereby reducing the ageing of the installation
