ABB Arc fault protective device

Arc Fault Detection Device (AFDD) with Miniature Circuit Breaker (MCB) according to IEC/EN 62606 (VDE 0665-10) and IEC/EN 60898-1 (VDE 0641-11) provides protection against series and parallel arc faults, overcurrent protection (overload or short circuit), overvoltage protection (only for internal AFDD), and protection against electrically ignited fires in accordance with DIN VDE 0100-420. Mandatory application areas according to DIN VDE 01000 are in single-phase AC systems with In = 16 A in sleeping or living areas of homes and day care facilities for children, disabled or elderly people, or in barrier-free apartments, as well as in rooms or locations with fire risk (with special fire hazards, fire-risk workplaces), predominantly made of combustible building materials. The use of AFDDs is recommended in rooms with sleeping accommodations, rooms or locations with fire-spreading structures, and final circuits with high connection power. In general, the AFDD is also recommended to enhance fire protection against electrically ignited fires. An LED indicator is provided to identify the cause of tripping. Its patented terminal blocks with Push-In technology ensure easy and secure connection and handling. The upper outgoing Push-In terminal can accommodate conductors of up to 2 x 4 mm². On the input side, the PSX phase rails can be used for cross-wiring. Rated switching capacity according to IEC/EN 60898-1 Icn = 6 kA. AFDD+MCB SX-ARC1 is single-pole protected (LS), double-pole switching.
