FILS for combined short-circuit protection and touch protection. Type A FI circuit breaker, PSESSF, T=70mm 30mA, 10kA, 1-pole 13A C-characteristic. The patented FILS switches from Siemens are an essential component of the SENTRON protection devices for electrical installations, enabling combined personal, fire, and line protection in a single device. In addition to detecting fault currents, they also provide reliable protection against short circuits and overloads thanks to the integrated overcurrent protection device. The Siemens FILS switches, which combine residual current and circuit protection, stand out primarily due to: 1. Increased operational safety and system availability thanks to the separate disconnection of the affected circuit. 2. Whether sinusoidal alternating fault currents or smooth direct fault currents, Siemens offers the suitable type for all requirements as well as special versions. 3. The data matrix code on the front of the device provides quick and easy access to all information about the FILS switch. 4. Ensure compliance with standards: The FILS switches meet the requirements of DIN VDE. 5. Optimal technology for your safety, exclusively from Siemens. Siemens offers a comprehensive portfolio of protection, switching, measuring, and monitoring devices, installation distributors, as well as switches and sockets for a safe, efficient electrical infrastructure in buildings and industry.
