Product details
FI/LS for combined short-circuit protection and touch protection. The patented FI/LS switches from Siemens are an essential component of the SENTRON protective devices for electrical installations, enabling combined protection for people, fire, and circuits 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 FI/LS switches, which combine residual current and circuit protection, stand out for the following features:
1. Increased operational safety and system availability due to separate disconnection of the affected circuit.
2. Whether sinusoidal alternating fault currents or smooth direct fault currents - Siemens offers the right type for all requirements, including special versions.
3. Reliable safety during installation thanks to standard touch and gripping protection.
4. Tool-free removal from the DIN rail or busbar connection through convenient slider manual operation.
5. Clearly visible switching position indicator.
6. A data matrix code on the front of the device provides quick and easy access to all information related to the FI/LS switch.
7. Be compliant with standards: The FI/LS switches meet the requirements of DIN VDE.
8. Optimal technology for your safety - exclusively from Siemens.
Siemens offers a comprehensive portfolio of protective, switching, measuring, and monitoring devices, distribution systems, as well as switches and sockets for safe and efficient electrical infrastructure in buildings and industry.
