Siemens 6AG1221-1BF32-4XB0 6AG12211BF324XB0 PLC add-on module

Residual current operated circuit breaker, 4-pole, type A, In: 40 A, 30 mA, Un AC: 400 V The RCD is the residual current device for touch protection The patented residual current protective devices from Siemens are an important element of the SENTRON protective components for electrical installations, as they prevent life-threatening electrical accidents by safely disconnecting hazardous residual currents through grounding. Electrically ignited fires can be prevented as they occur. Whether the problem is direct contact with energized operating parts or indirect contact with equipment, protection is achieved primarily by rapid shutdown. Key features of the Siemens 5SV RCCB: 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 with standard reach-around and touch protection. 4. Toolless removal from the DIN rail or from the bus bar assembly with convenient manual slide actuation. 5. The data matrix code on the front of the device provides quick and easy access to information on all aspects of the residual current operated circuit breaker. 6. Be protected according to the standards: The residual current operated circuit breakers correspond to the provisions of the DIN VDE. 7. Optimized technology for your safety – only from Siemens. www.siemens.com/global/en/home/products/energy/low-voltage/components/sentron-protection-devices/residual-current-protective-devices.html.
