Legrand 415958 DX3 AFDD fire protection switch with FI/LS switch B16A,1P+NR,10kA,30mA, type A, 3TE

Legrand Fire protection switch DX3 STOP ARC. According to EN 62606, VDE 0665-10, EN 61009-1,VDE 0664-20. AFDD with FI/LS switch, 1-pole with switching neutral conductor, type A for alternating and pulsating direct fault currents, undelayed, rated fault current Idn 30 mA, shock voltage up to 250 A Legrand Forked comb rails. Auxiliary equipment can be installed. Trigger display: yellow=fault current or test button triggering, colorless= short-circuit or hand triggering. The fire protection switch DX3 STOP ARC is a device combination of fault arc protection device AFDD with fault current protection switches and circuit protection switches. The one-pole protected and two-pole connected AFDD with FI/LS switch provides a secure all-pole disconnection with the following fault images: fault current against ground, overload, short circuit, parallel and serial fault arcs. With LED state indicator for the recognition of the operating status, detect indicator for the visual in case of fault arc triggering. The self-monitoring of the AFDD unit takes place via an internal daily self-test. The causes for the formation of faulty arcs are, for example: damaged conductor insulation by nails, screws or bores, squeezed cables or lines, loose or faulty clamping points in sockets or screw connections.
