Expert knowledge for electrical planning engineers

Creating arc fault protection concepts with confidence

Why is arc fault protection so important? It is difficult to get this theme across to the customer properly. We are here to support you with technical background information, argumentation aids, seminars and newsletters.
The DEHNshort arc fault protection system provides reliable protection. For low-voltage switchgear assemblies up to 690 V with a short-current withstand capacity of up to 110 kA.

A safe bet for you as a planning engineer: We actively support you when designing an arc fault protection system. The DEHNshort application manual, our unique design aids and our system-specific on-site consultation service enhance your competence and save valuable time.

Info on standards

Three international standards are currently being prepared for low-voltage applications. These address

  • Arc fault detection systems 
    Standard IEC 60947-9-2 is at the CD (Committee Draft) stage which means that the working group has put forward a proposal to the national standards committees for their comments.
  • Arc fault quenching devices 
    Standard IEC 60947-91-1 is at the CDV (Committee Draft for Vote) stage; the subsequent FDIS (Final Draft International Standard) will be prepared shortly.
    This document has already been voted on and it is now a matter of integrating the final comments in the FDIS.
  • Integration in low-voltage switchgear assemblies 
    A CD is expected shortly for IEC/TS 63107, too.
