RCCB, 4-pole, type A, selective, In: 40 A, 300 mA, Un AC: 400 V

УЗО ТИП A 40A 3+N-ПОЛ 300MA 400V 4MW SELECTIVE The RCD is the residual current device for touch protection The patented residual current protective devices from Siemens are an important component of the SENTRON protective components for electrical installations because they prevent life-threatening electrical accidents by safely disconnecting hazardous residual currents through grounding. Electrically ignited fires can be prevented as they occur. Whether by direct contact with energized operating parts or by indirect contact with equipment, protection is mainly achieved by a quick shutdown. The Siemens 5SV RCCBs are characterized primarily by: 1. Comprehensive protection from electric shock for personnel and property. 2. Whether sinusoidal residual alternating currents or smooth residual direct currents, Siemens provides the right type for all requirements and special versions. 3. Reliable safety during installation due to standard reach-around and touch protection. 4. Toolless removal from the standard mounting rail or from the busbar assembly simply by operating a manual slide. 5. The data matrix code on the front of the device provides quick and easy access to information on all aspects of RCCBs. 6. Be protected according to the standards: The RCCBs meet the provisions of DIN VDE. 7. Optimized technology for your safety - only from Siemens. https://www.siemens.com/global/en/home/products/energy/low-voltage/components/sentron-protection-devices/residual-current-protective-devices.html. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe and efficient electrical infrastructure in buildings and industry.
