Siemens RCD/LCB, 6 kA, 1P+N, type A, 30 mA, B-Char, In: 16 A, Un AC: 230 V. RCD/LCB for combined short-circuit protection and touch protection. The patented RCDs from Siemens are an important component of SENTRON protection devices for electrical installations and enable combined personal, fire and line protection in just one device. In addition to detecting residual currents, they also offer reliable protection against short circuits and overloads thanks to the integrated overcurrent protection device. As a combination of residual current circuit-breaker and miniature circuit-breaker, Siemens residual current circuit-breakers are characterised above all by 1. increased operational safety and system availability thanks to separate disconnection of the affected circuit. 2. whether sinusoidal AC residual currents or smooth DC residual currents - Siemens offers the right type and special versions for all requirements. 3. reliable safety during installation thanks to the standardised gripping and contact protection. 4. tool-free release from the top-hat rail or from the busbar system thanks to convenient manual slide 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. 7. be protected in accordance with standards: The RCDs comply with the provisions of DIN VDE. 8. optimum technology for your safety - only from Siemens. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices as well as distribution systems for safe, efficient electrical infrastructure in buildings and industry.
