FI/LS switch, 10 kA, 1P+N, type F, super-resistant K, 30 mA, C-Char, In: 40 A, Un AC: 230 V FI/LS for combined short-circuit protection and contact protection. The patented FI/LS switches from Siemens - as an important component of the SENTRON protective devices for electrical installations - enable combined personal, fire and line protection in just one device. In addition to detecting residual currents, they also offer reliable protection against short circuits and overloads thanks to the integrated overcurrent protection device. The Siemens FI/LS switches as a combination of residual current and circuit breaker are characterized above all by: 1. Increased operational reliability and system availability thanks to separate shutdown of the affected circuit. 2. Whether sinusoidal alternating residual currents or smooth direct residual currents - Siemens offers the right type and special designs for all requirements. 3. Reliable safety during installation thanks to the anti-grip and touch protection included as standard. 4. Tool-free removal from the top hat rail or from the busbar assembly thanks to convenient manual slider operation. 5. Clearly visible switch position display. 6. Data matrix code on the front of the device provides all information about the residual current device quickly and easily. 7. Be protected in accordance with standards: The residual current devices comply with the provisions of DIN VDE. 8. Optimum technology for your safety - only from Siemens. www.siemens.de/fehlerstromschutz. 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.
