Legrand fire protection switch DX3 STOP ARC. According to EN 62606,0665-10, EN 60898-1,0641-11. AFDD with miniature circuit breaker, 1-pole with switching neutral conductor, miniature circuit breaker part: C characteristic, rated current In 20 A, rated switching capacity Icn 6 kA according to EN 60898-1, rated voltage Un 230 VAC, rated frequency 50 Hz, energy limitation class 3, fastening on top hat rail EN 60715 using snap-in fastenings, clear information on the front of each device, clear switch position indicator red/green on the switch lever, with labeling window, neutral conductor connection on the right, can be mounted using Legrand pin comb rails. Auxiliary devices can be attached. The DX3 STOP ARC fire protection switch is a device combination of an arc fault protection device (AFDD) and a circuit breaker. The single-pole protected and double-pole switched AFDD with circuit breaker offers safe all-pole shutdown in the event of the following faults: overload, short circuit, parallel and serial arc faults. With LED status display for detecting the operating status, signal display for visual detection when an arc fault is triggered. The AFDD unit monitors itself using an internal daily self-test. Causes of arc faults include: Damaged conductor insulation caused by nails, screws or holes, crushed cables or lines, loose or faulty terminals in sockets or screw connections.
