With comprehensive arc fault protection, you protect people, improve fire safety and optimise system availability.
Assess risk
Minimise risk
A risk assessment helps you identify the risk of arc faults at an early stage. On this basis, you can take the appropriate measures to prevent arc faults and reduce the effects of arc energies. The process for optimising your arc fault protection concept could look like this.
Recognise dangers, prevent damage
An arc fault is not a rare event and is therefore a hazard to be taken seriously. This fault can occur due to a technical defect, human error, impurities or foreign bodies in the system. You prevent far-reaching consequences with comprehensive arc fault protection for systems and employees.
Follow the Hierachy of Risk Controls
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 hierachy 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 hierachy 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 = Labeling 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.
