Siemens RCD/MCB, 6 kA, 1P+N, Type A, 30 mA, B-Characteristic, In: 16 A, Un AC: 230 V. RCD/MCB for combined short circuit protection and touch protection. Siemens' patented RCD/MCB devices are an essential component of the SENTRON protection devices for electrical installations, enabling combined protection for people, fire, and wiring in a single unit. In addition to detecting fault currents, they also provide reliable protection against short circuits and overloads thanks to the integrated overcurrent protection device. The Siemens RCD/MCB, as a combination of residual current and circuit protection switch, stands out for several reasons: 1. Increased operational safety and system availability due to the separate disconnection of the affected circuit. 2. Whether sinusoidal alternating fault currents or smooth direct fault currents - Siemens offers the right type and special versions for all requirements. 3. Reliable safety during installation thanks to standard touch and grip protection. 4. Tool-free removal from the DIN rail or busbar connection through convenient slider manual operation. 5. Clearly visible switching position indicator. 6. Data matrix code on the front of the device provides quick and easy access to all information about the RCD/MCB. 7. Ensure compliance with standards: The RCD/MCBs meet the requirements of DIN VDE regulations. 8. Optimal technology for your safety - exclusively from Siemens. Siemens offers a comprehensive portfolio of protection, switching, measuring, and monitoring devices, as well as distribution systems for safe and efficient electrical infrastructure in buildings and industry.
