Fire protection switch 2-pole, 32 A, 0.03 A, C-Char, Type A, short-time delayed

Arc-fault detection devices (AFDD) reduce the risk of fire caused by defects in the electrical installation. They disconnect the affected part of the system when serial and parallel arc faults occur. Arc-fault detection devices are prescribed for bedrooms and common rooms in nurseries, nursing homes and accessible housing as well as in facilities with a fire risk. DAFDD 1 combine the detection of arc faults with line protection and protection against residual currents in a compact package. The contact position indicators and the display tripped by residual current provide a quick overview. The RCBO component of this switch offers protection against residual currents of Type A independent of the mains voltage as well as against short-circuit and overload. Switches with tripping characteristic C are optimised for electric circuits with high inrush or peak currents. Switches in the KV design are much less sensitive to brief pulsed fault currents due to their response delay. Being lightning-resistant devices, they increase system availability and can effectively be used instead of a standard switch. as their protective function is retained.
