Protection of personnel and switchgear assembly – optimum system availability

Arc faults generate temperatures of over 10,000° C and pressure waves of up to 2 bar. Toxic combustion residue escapes into the immediate surroundings.

Secure system availability – round the clock protection

With DEHNshort, you can optimise the availability of your system and free your mind to concentrate on other things. It detects arc faults as soon as they arise and quenches them within milliseconds.

What do you have to lose if your production comes to a standstill? What are your delivery commitments towards your customers? The price of active arc fault protection is only a fraction of the production downtime costs. It definitely pays off!

Arc faults endanger your employees

When working on switchgear assemblies, particularly open systems, electricians risk severe injury or even death.
You can fulfil the duty of your company to protect your personnel by providing them with the special

DEHNcare protective equipment and installing the DEHNshort arc fault protection system.

Without reportable work-related accident

As laid down in occupational health and safety legislation, you as the employer are responsible for the safety of your employees.

Update your risk analysis and review:

  • What potential danger does the assembly present?
  • Where is my assembly and who has access to it?
  • How can I provide the best possible safety for my employees?

You can quickly find the right protection system depending on the type of assembly, the energy density and the requirements:

Round the clock protection for your assembly
DEHNshort: The arc fault protection system detects an arc fault as soon as it arises and quenches it within milliseconds. After the fault localisation, exchange of the quenching device and insulation measurements, the assembly can be recommissioned and production resumed.
For the protection of your employees
DEHNcare: Protects electricians when working on open switchgear assemblies. The personal protective equipment includes a jacket and trousers or a coat made of arc-fault-tested, flame-retardant material; an electrician’s safety helmet with an energy absorbing protective face shield; and gloves with a long gauntlet of leather and neoprene.
