Protection measures against arc faults – with concept
An arc fault is not a rare phenomenon, it is a hazard which must be taken seriously. It occurs as an electrical gas discharge due to a technical defect, maloperation, impurities or foreign objects in the system. Therefore, for optimum protection, plan your arc fault protection holistically. With the right measures, you can ensure the safety of your employees, optimise the fire protection of your electrical system and ensure that it runs reliably.
Safe when it matters most.

Follow the Hierarchy of Risk Control
As a general rule, hazards are always eliminated at their source. If this does not suffice, further preventive measures can be taken as per the hierarchy of risk control in accordance with NFPA 70 E.
Elimination
e.g. disconnect all electrical equipment completely
Substitution
e.g. internal arc fault mitigation system (IAMS)
Engineering controls
e.g. adjustment of circuit breaker settings
Awareness
e.g. arc flash labelling
Administrative controls
e.g. planned work procedures
PPE
e.g. arc-rated PPE
The right solution according to the hierarchy of risk control:
Substitution
The active arc fault protection system DEHNshort quenches arc faults within a few milliseconds, making it one of the most powerful protection systems on the market.
Elimination
Work in and on electrical installations can be life-threatening. To prevent electrical accidents, follow the five safety rules (dead working)
EN 50110-1!
Engineering controls/Awareness = Labelling DEHNarX
The DEHNarX service determines the risk of an arc fault according to DGUV-I 203-077 and the American process
NFPA 70E / IEEE 1584.
Administrative controls
Whether it is an in-person seminar, an online seminar or Web-based training, here you will find the right seminar for you relating to all topics. Anywhere digitally or on site across Germany.
Why arc faults are dangerous
What are arc faults? Why are they so dangerous and how can you protect yourself against them? We will explain it to you and tell you which protection class is right for you.
Recognising the risk of arc faults
Use this checklist as a guideline to assess arc fault hazards in your electrical systems and optimise your company-wide arc fault protection concept. If you have any questions, please contact our arc fault expert.
