DEHNshort – Safe when it matters most

Your low-voltage switchgear assembly board needs permanently reliable arc fault protection?

DEHNshort offers reliable arc fault 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 errors when working on the assembly
Contamination
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 safety: Highest possible system availability and protection of employees.

Plan your optimum DEHNshort active arc fault protection system in good time.

O.K, .... and how do I go about it?

Step 1 – Exploratory stage

Initial meeting

Together, we ascertain:

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

Protection concept

Which criteria must your protection concept fulfil?

Personal protection? System protection? Or a combination of the two?
Availability of the switchgear assembly?
Conventional (passive) or active arc fault protection?

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.

Only this performance level offers the possibility to reenergize the assembly as soon as possible
