AFD unit block for LS and FI/LS, 16A - Residual current breaker 5SM6021-2 – Siemens – 4001869525792: Fire protection switch block AFDD, f.FI/LS, 16A 5SM6021-2 Fire protection switch block AFDD, 1-16A 230V for LS and FI/LS switches 1+N 2TE The fire protection switch with SIARC technology is the protective device in the event of arcing faults (AFDD) . The proven fire protection switch with patented SIARC technology from Siemens - as an important part of the SENTRON protective components for electrical installations - offers safety against dangerous arcing faults. No other protective device, neither the circuit breaker, FI circuit breaker nor a security system, can reliably detect these serial dangers. Arc faults occur e.g. B. due to damaged cables, loose contacts or insulation faults and often lead to dangerous fires. Fire protection switches detect these dangerous arc faults at an early stage and switch off safely before a fire occurs. 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. Maximum technical performance in fire protection by covering the previous gap in protection. 4. Easy installation in conjunction with line protection and FI/LS switch. 5. Proven North American technology - tailored for the European market. 6. Scan the data matrix code on the device and access all information about the fire protection switch quickly and easily. 7. Optimal technology for your safety - only from Siemens. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for the safe, efficient electrical infrastructure in buildings and industry.
