Residual current circuit breaker, 4-pole, type A, In: 40 A, 30 mA, Un AC: 500 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, because 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 parts that are live during operation or through indirect contact with equipment - protection is achieved primarily through rapid switching off. The Siemens residual current circuit breakers 5SV 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 versions for all requirements 3. Reliable safety during installation thanks to the grip and contact protection included as standard 4. Tool-free removal from the top hat rail or from the busbar assembly thanks to convenient manual slide operation 5. Data matrix code on the front of the device provides all information about the residual current circuit breaker quickly and easily 6. Be protected in accordance with standards: The residual current circuit breakers comply with the provisions of DIN7. 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.
