Fire protection devices, fault-arc protection devices (AFDD) reduce the risk of fire due to defects in the electrical installation. If serial and parallel error arcs occur, they switch off the affected system part. They are prescribed for use in accordance with DIN VDE 0100-420 for sleep and recreation rooms of children's daycare centers, retirement homes and barrier-free apartments as well as in fire-endangered operating areas DAFDD 1 combines compactly the detection of error arcs with line and fault current protection. Contact status displays and the fault current triggered display provide for a quick overview. The RCBO-part offers protection against fault currents of the type A independent of mains voltage as well as against short-circuit and overload. Switches with the characteristic B are the standard protection for light and socket circuits. The standard version is optimized for monitoring circuits with a rated voltage of 230 V and a rated frequency of 50 Hz. Features: Combi device with three functions; two-pole; neutral position variable; AFDD according to IEC/EN-62606; RCBO according to IEC/EN-61009; Continuous self-monitoring of the AFD unit; tripping of FI and LS functions independent of mains voltage; display of AFDD trigger reason; contact position display; fault current tripping indicator; compact size for all rated currents; high short-circuit resistance; bracket terminals with rear plug protection; tri-stable stop slide for easy installation and removal; Mounting type: rapid mounting on mounting rail; mounting position, arbitrary; feed from below; application areas: Protection of electric circuits in residential and functional buildings and industrial systems with TN-S and TN-C-S networks; the use in systems with TN-C networks and for protection of circuits is excluded. In which power electronics equipment can cause smooth DC fault currents or fault currents with frequencies not equal to 50 Hz.
