ABB 2CSA255901R9165 AFDD+LS S-ARC1-B16, 6kA, 1P+N, 2TE fault arc protection device + LS

Fault arc protection device (AFDD) with automatic fuse (MCB) according to IEC/EN 62606 (WDE 0665-10) and IEC/EN 60898-1 (WDE 0641-11) provide protection against serial and parallel fault arcs, protection against overcurrent (overload or short circuit), protection against overvoltage (only for AFDD internal) and protection against electrically ignited fires according to DIN20WDE 0. Mandatory areas of application according to DIN WDE 01000 are in single-phase AC voltage systems with In = 16 A in sleeping or staying areas of homes and day-to-day facilities for children, disabled or old people or barrier-free homes, as well as in rooms or places with fire risk (with special fire risk, fire-prone facilities), predominantly/mainly from combustible building materials (classification of combustability of building materials). It is recommended to use Afds in rooms with sleeping facilities, rooms or places with a fire-promoting structure and high connection power terminal circuits. In general, the AFDD is also recommended to increase fire protection against electrically ignited fires. LED indicator to identify the cause of triggering. Feeding from above or below as desired, transverse wiring, for example to FI protection switches in the rear terminal area, is possible. Accessory of the system per M compact®. IEC/EN 60898-1 Icn=6kA. AFDD+MCB S-ARC1 is 1polig protected (LS), switching 2polig.
