DC technology is gaining ground. Renewable energies and electromobility are just two of the key technology drivers. New challenges are emerging for switching technology, especially at high power levels:

  • Depending on the level of the switched power, arcs form that can result in damage to switchgear.
  • Since no zero crossing of the voltage occurs in DC voltage applications, extinguishing these switching arcs is technically challenging.
