DX3 STOP ARC

NEW 3 FIRE RISKS OF ELECTRICAL ARCS DX STOP ARC These appear in cables or their connections. ELECTRICAL ORIGIN AND ASSOCIATED PROTECTION DEVICES EXAMPLES OF SITUATIONS WHICH CAN LEAD TO THE APPEARANCE OF ELECTRICAL ARCS EXTRA

PROTECTION The risk of fire is real and is much undoubtedly represents is enhancing its protection offer feared, as it can have devastating one of the most complex aspects with a range of circuit breakers FOR PEOPLE consequences for both people of safety. Statistical studies show capable of detecting faults which and property. Paradoxically, that a third of domestic fires up to now have been impossible AND PROPERTY its origins are still not well are of electrical origin. to detect using conventional Power supply cable Faulty power supply Cable damaged during Cable damaged known and even today, taking Ever keen to provide a greater protection methods. subjected to too much cable (excessive wiring operations accidentally bending handling) the risk of fire into account level of safety, Legrand
