ABB 2CSF204701R1400 FI F204B+40/0.03

F200 Type B+ for smooth DC residual currents and enhanced preventive fire protection. All-current sensitive, with a short delay of 10 ms, and shock current resistant up to 3 kA. Residual current circuit breakers (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 B+ series RCCBs ensure protection against sinusoidal alternating currents, pulsating currents, and smooth DC residual currents to ground. They offer fault protection (protection against indirect contact), additional protection (with I?n = 30 mA), and fire protection (with I?n = 300 mA). They comply with product standards for Type A RCDs 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 you need for your installation tasks. The Type B+ RCCBs detect smooth DC residual currents, respond earlier than Type B RCCBs with a maximum of 420 mA, and have 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.
