The RCD block (RCU) is designed for customer-side installation with circuit breakers of the S200 series. The resulting RCD/MCB combination (RCBOs) provides protection for persons and property as well as protection against electrically ignited fires in accordance with DIN VDE 0100-410 and DIN VDE 0100-530. They ensure protection for 1P+N, 2P, 3P, 3P+N, or 4P circuits against overload and short-circuit currents, protection against sinusoidal alternating currents and pulsating currents with a smooth DC residual current component of up to 6 mA to earth. Additionally, they provide fault protection (protection against indirect contact), supplementary protection (with I?n = 30 mA), and fire protection (with I?n = 300 mA). They comply with the product standard IEC/EN 61009 Annex G. Areas of application include household, commercial, and industrial uses. The extensive range of accessories provides everything you need for your installation tasks. The rated breaking capacity when using S200 MCBs is: 6 kA for S200, 10 kA for S200 M, and 25 kA for S200 P.
