The FI block (RCU) is for customer-side assembly with automatic circuit breakers from the S200 series. The resulting FI/LS combinations (RCBOs) offer personal and material protection as well as protection against electrically ignited fires in accordance with DIN0100-410 and DIN0100-530. They guarantee protection of 1P+N, 2P, 3P, 3P+N or 4P circuits against overload and short-circuit currents, protection against sinusoidal alternating currents and pulsating currents with smooth DC residual current of up to 6 mA to earth. As well as fault protection (protection against indirect contact), additional protection (with I n 30 mA) and fire protection. They comply with the product standard IEC 61009 Appendix G. Areas of application are commercial and industrial applications. The extensive range of accessories offers you everything you need for your installation tasks. DDA200 A 110 V is a special version of a residual current device with a test button voltage range Ut = 95 - 245 V. The special version is also available for 400 V in the two-pole version for two-phase industrial applications where the voltage between the phases is 400 V.
