DEHN Arc Fault Protection

Handling Arc Faults - Protecting staff

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.

Active or passive arc fault protection? The decision-making aid offers a preliminary overview and makes it easier for you to plan and select the right products.

Protect your staff with DEHNcare®

Passive arc fault protection: 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 stipulates that employers are responsible for the protection of their employees.
The DEHNcare® product range provides all the personal protective equipment components your team needs.

 

Ensure system availability with DEHNshort

Active arc fault protection: 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 can turn your attention to other things.

Optimise system availability – keep costs under control

As the operator of a system you are responsible for the safety of your personnel. You want to optimise system availability and keep an eye on the costs at the same time? Not as easy as it sounds!

Arc faults endanger your staff and threaten the permanent electrical power supply. A fault in the switchgear assembly can soon be an expensive business.

So, it is ideal if arc faults are detected and automatically quenched as soon as they arise. Staff enjoy optimum protection and the system is back in operation in the shortest possible time.
