Fire protection switch block AFDD, 1-40A 230V for LS and FI/LS switches 1+N 2TE The fire protection switch with SIARC technology is the protection device for arc faults (AFDD). The tried and tested fire protection switch with patented SIARC technology from Siemens - as an important component of the SENTRON protection components for electrical installations offers protection against dangerous arc faults. No other protection device, neither the miniature circuit breaker, residual current circuit breaker nor a fuse system, can reliably detect these serial dangers. Arc faults are caused, for example, by damaged cables, loose contacts or insulation faults and often lead to dangerous fires. Fire protection switches detect these dangerous arc faults early on and switch off safely before a fire starts. The Siemens fire protection switch is characterized above all by: 1. Patented SIARC detection technology 2. Reliable and comprehensive protection for people, systems and assets. 3. Top technical performance in fire protection by covering the previous protection gap. 4. Easy installation in conjunction with line protection and residual current devices. 5. Proven North American technology - tailored for the European market. 6. Scan the data matrix code on the device and quickly and easily access all information about the fire protection switch. 7. Optimum technology for your safety - only from Siemens. www.siemens.de/fireprotectionswitch. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe, efficient electrical infrastructure in buildings and industry.
