Residual current circuit breaker, 4-pole, type B, short-time delayed, In: 40 A, 30 mA, Un AC: 400 V The residual current circuit breaker is the residual current device for contact protection. The patented residual current devices from Siemens are an important part of the SENTRON protective components for electrical installations, as they prevent life-threatening electrical accidents by safely switching off dangerous residual currents to earth. Electrically ignited fires can be prevented before they even start. Whether through direct contact with live parts or through indirect contact with equipment - protection is achieved primarily through rapid switching off. The Siemens 5SV residual current circuit breakers are characterized above all by: 1. Comprehensive protection for people and property against electric shock. 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 standard anti-touch protection. 4. Tool-free removal from the top hat rail or from the busbar assembly thanks to convenient manual slider operation. 5. Data matrix code on the front of the device provides all information about the residual current device quickly and easily. 6. Be protected in accordance with standards: The residual current devices comply with the provisions of DIN VDE. 7. 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.
