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
Foreign objects, like forgotten tools
Animals in the assembly

This means that there is always a risk, even in the most modern assemblies.

An arc fault protection system provides security: Greatest possible system availability and protection of employees.

Quenching arc faults as soon as they arise

Arc faults in switchgear assemblies release a huge amount of energy. The heat and pressure are extreme. The result is the failure or even complete destruction of the switchgear assembly. This affects all the devices and systems connected. What is needed, is protection solutions like the DEHNshort protection system which enable quick and reliable quenching of an arc fault.
