Residual current circuit breakers (RCCBs) 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. The residual current circuit breakers of the FX200 series ensure 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) and additional protection (with I¿n = 30 mA). They meet the product standards IEC/EN 61008-1, 61008-2-1, 61543 (VDE 0664 10, 11, 30). Their patented connection terminals with push-in technology ensure simple and safe contact and handling. Conductors of up to 25 mm² can be connected to the upper, input-side screw terminal. On the output side, the PSX phase rails can be used for cross-wiring. For possible further wiring, conductor cross-sections of up to 10 mm² can be connected directly to the device to the lower, additional screw connection terminal in protection class IP20. Numerous approvals make the FX200 suitable for use in household and commercial applications.
