ABB FI F204B100/0.03L

F200 Type B+ for smooth DC residual currents and enhanced preventive fire protection. All-current sensitive, with a short delay of 10 ms, and surge current resistant up to 3 kA. Residual current devices (RCCBs) provide protection for persons and property as well as protection against electrically ignited fires in accordance with DIN VDE 0100-410 and DIN VDE 0100-530. The F200 series residual current circuit breakers ensure protection against earth faults for sinusoidal alternating currents, pulsating currents, and smooth DC residual currents. They offer fault protection (protection against indirect contact), additional protection (with IΔn ≤ 30 mA), and fire protection (with I∆n ≤ 300 mA). They meet the product standards for RCDs Type A IEC/EN 61008-1, 61008-2-1, 61543 (VDE 0664 10, 11, 30) and for Type B+ DIN VDE 0664-400. Their primary applications are in commercial and industrial settings. The extensive range of accessories provides everything needed for installation tasks. The RCCB Type B+ detects smooth DC residual currents, reacts earlier than the RCCB Type B with a maximum of 420 mA, and has a frequency range of 0 to 20 kHz for detecting the residual current. Thus, they offer enhanced preventive fire protection (extended fire protection according to DIN VDE 0100-530) for fire-hazardous workplaces and commercial units.
