Handling arc faults - Protecting staff

DEHNshort - Safe when it matters most

What are the reasons for arc faults?

Arc flashes are often caused by errors made when working on the switchgear assembly, contaminants, foreign objects like forgotten tools, or by animals getting into the assembly. This means that even the most modern switchgear assemblies are at risk.

An arc fault protection system gives you the safety you need

  • to effectively protect your staff
  • to optimise the availability of the switchgear assembly and
  • to design in conformity with valid regulations.

Different protective systems are available depending on the purpose of application and power density of the switchgear assembly to suit the individual situation and type of system.

Ensure system availability with DEHNshort

Economically, an arc fault can be devastating. A damaged switchgear assembly means no electricity! Production stop! The necessary repairs are often extensive. Sometimes the whole assembly needs to be replaced. A power failure is simply not acceptable for a modern company in today’s competitive environment. DEHNshort reacts in your switchgear assembly before the arc fault can cause serious damage and you are free to turn your attention to other things.

Protect your staff with DEHNcare

In case of an arc fault, enormous amounts of energy are released in a matter of milliseconds. Anyone close to the switchgear assembly at the time is in great danger. Extreme heat, toxic combustion residues and explosive pressure waves are the major hazard. Health and safety legislation clearly stipulate that employers are responsible for the protection of their employees. The DEHNcare product range provides all the personal protective equipment components your team needs.
