Arc Fault Protection System DEHNshort

Your low-voltage main distribution board needs permanently reliable protection?

DEHNshort offers reliable protection for switchgear assemblies up to 110 kA - 690V. The modular system is individually configured to suit the assembly at hand. With arc fault quenching times of just a few milliseconds, it is one of the fastest protection systems on the market.

These are the most common reasons for arc faults:

  • Human error when working on the assembly
  • Contaminants in the assembly
  • Foreign objects, e.g., forgotten tools
  • Animals in the assembly

It's obvious, that there is always a risk, even in the most modern assemblies. And there is a lot at stake because arc faults present mortal danger. From an economic point of view, arc faults can entail immense costs, e.g., due to production downtime and extensive repairs.

Implement an active arc fault protection with DEHNshort in time.

This is how

Exploratory stage

At the initial meeting, we ascertain:

  • What are your protective aims?
  • What are the technical framework conditions?
  • Design verification?

Which criteria must your protection concept fulfil?

  • Personal protection? System protection? Or a combination of the two?
  • What are the requirements on availability of the switchgear assembly?
  • Do you want conventional or active arc fault protection?

These are the next steps optimised for your branch:

Quenching arc faults as soon as they arise

DEHNshort, the modular arc fault protection system detects arc faults with the aid of current and light sensors. The reaction time of just a few milliseconds limits the incident energy to a minimum. DEHNshort protects human life and equipment to a much higher degree than required by the currently valid standard IEC TR 61641.
