Residual current circuit breakers (RCCBs) of the F400 series offer protection for people and property as well as protection against electrically ignited fires in accordance with DIN VDE 0100-410 and DIN VDE 0100-530. The residual current circuit breakers of the F400 series ensure protection against sinusoidal alternating currents and pulsating currents 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 standards IEC/EN 61008-1, 61008-2-1, 61543 (VDE 0664 10, 11, 30). Contact is made directly via the Smissline TP plug-in base system.
