Fire protection switches, arc fault protection devices (AFDD), reduce the risk of fire caused by defects in the electrical installation. They switch off the affected part of the system when serial and parallel arc faults occur. According to DIN VDE 0100-420, they are required for bedrooms and common rooms in daycare centers, retirement homes and barrier-free apartments as well as in fire-prone premises. DAFDD 1 compactly combines the detection of arc faults with line and residual current protection. Contact position indicators and the residual current tripped indicator provide a quick overview. The RCBO part offers protection against type A residual currents as well as against short circuits and overloads, independent of the mains voltage. Switches with tripping characteristics 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. Properties: Combination device with three functions, two-pole, variable neutral conductor position, AFDD according to IEC/EN-62606, RCBO according to IEC/EN-61009, continuous self-monitoring of the AFD unit, mains voltage-independent triggering of the FI and LS functions, display of AFDD tripping reason, contact position display, residual current tripping display, compact size for all rated currents, high short-circuit strength, clamping yoke terminals with rear protection, tristable locking slides for easy installation and removal, mounting type: quick attachment to mounting rail, installation position as desired, feed from below, areas of application: protection of circuits in residential and commercial buildings as well as industrial plants with TN-S and TN-CS networks, use in systems with TN-C networks and for protecting circuits in which power electronics equipment can cause smooth DC residual currents or residual currents with frequencies other than 50 Hz is excluded.
