Arc fault protective device (AFDD) with automatic circuit breaker (MCB) according to IEC/EN 62606 (VDE 0665-10) and IEC/EN 60898-1 (VDE 0641-11) offer protection against serial and parallel arc faults, protection against overcurrent (overload or short circuit), protection against overvoltage (only for AFDD internal) and protection against electrically ignited fires according to DIN0100-420. , Mandatory areas of application according to DIN01000 are in single-phase alternating current systems with In 16 A in bedrooms or common rooms in homes and day care centers for children, disabled or elderly people or in barrier-free apartments as well as in rooms or places with a fire risk (with a particular fire risk, fire-prone premises), predominantly/mainly made of flammable building materials (the classification of the flammability of the building materials is the responsibility of the manufacturer of the wooden house, for example), endangerment of irreplaceable goods - cultural assets with a particularly high value and in single-phase final circuits that supply electrical equipment in the areas mentioned or cross these areas. The use of AFDDs is recommended in rooms with sleeping facilities, rooms or places with a fire-spreading structure and final circuits with a high connected load. , In general, the AFDD is also recommended to increase fire protection against electrically ignited fires., LED indicator to identify the cause of the activation. Can be fed in from above or below, cross-wiring e.g. to residual current circuit breakers in the rear terminal area is possible. System pro M compact® accessories can be attached. Rated switching capacity according to IEC/EN 60898-1 Icn=6kA. AFDD+MCB S-ARC1 is 1-pole protected (LS), 2-pole switching.
