Residual current circuit breaker, 4-pole, type A, In: 100 A, 500 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 component of the SENTRON protective devices 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 residual current circuit breakers are characterized 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 for all requirements as well as special versions 3. Be protected in accordance with standards: All residual current circuit breakers comply with the provisions of DIN4. 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.
