Arc fault detection (fire protection switch - AFDD) iDPN N Arc, 1-pole+N, 16A, B characteristic, with integrated circuit breaker. Monitoring by the fire protection switch of 1-phase circuits. Monitoring by the fire protection switch of 1-phase circuits through a number of different electrical parameters.Collecting information that indicates the occurrence of a dangerous electrical arc. When dangerous arcs are detected, the fire protection switch trips to isolate the faulty outgoing circuits from the rest of the power network and thus reduce the risk of fire. In addition to protecting against arc faults, the device protects against overvoltages, short circuits and overloads.
