FILS for combined short-circuit protection and touch protection. Type A FI circuit protection device, PSESSF, T=70mm, 30mA, 10kA, 1-pole 25A C-characteristic. The patented FILS switches from Siemens are an essential component of the SENTRON protection devices for electrical installations and enable combined personal, fire, and line protection in just one 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, as a combination of residual current and circuit breakers, stand out primarily due to: 1. Increased operational safety and system availability thanks to separate disconnection of the affected circuit. 2. Whether sinusoidal alternating fault currents or smooth direct fault currents, Siemens offers the right type and special versions for all requirements. 3. The data matrix code on the front of the device provides quick and easy access to all information about the FILS switch. 4. Be compliant 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 safe and efficient electrical infrastructure in buildings and industry.
