Arc-fault detection device (AFDD)

70% of indoor fires are caused by faults in electrical wiring and electrical equipment

In places of disruption of normal electrical contact fault between the elements of electrical networks and electrical installations, sparking occurs, which is not recognized by circuit breakers, residual current devices or RCDs, because it does not cause an increase in current or its leakage to the ground.

AFDD detects dangerous sparking / arcing and disconnects the network from the power supply, preventing a fire.
