FI/LS combinations (RCBOs) offer personal and material protection as well as protection against electrically ignited fires in accordance with DIN VDE 0100-410 and DIN VDE 0100-530. They guarantee protection of 1P+N, 2P, 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 against earth. As well as fault protection (protection against indirect contact), additional protection (with I¿n = 30 mA) and fire protection (with I¿n = 300 mA). They meet the product standard IEC/EN 61009-1 (VDE 0664-20). Areas of application are household, commercial and industrial applications. The extensive range of accessories offers you everything you need for your installation tasks. Rated switching capacity Icn = 10,000 A according to IEC/EN 61009-1 (VDE 0664-20) for RCDs (residual current devices) in residential buildings and similar applications, Icu = 15 kA according to IEC/EN 60947-2 (VDE 0660-101) for MCBs (LS) in industrial applications. RCBO DS200 Type A is 2-/4-pole protected (LS), 2-/4-pole switching.
