FI/LS-switches (RCBOs) offer personal and property protection as well as protection against electrically ignited fires according to DIN VDE 0100-410 and DIN VDE 0100-530. They ensure protection of single-phase circuits against overload and short-circuit currents, protection for sinusoidal alternating currents and pulsating currents with smooth DC fault current of up to 6 mA against earth. As well as fault protection (protection against indirect contact), additional protection (with IΔn ≤ 30 mA) and fire protection (with I∆n ≤ 300 mA). They comply with the product standard IEC/EN 61009-1 (VDE 0664-20). The contact is made directly via the Smissline TP plug-in base system and the external conductor contact can be freely selected for single-phase devices (L1, L2 or L3)
