F200 Type B for smooth DC residual currents and operational safety, all-current sensitive, 10 ms short-time delayed, surge current resistant up to 3 kA (5 kA selective version). Residual current protective 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 residual current circuit breakers of the F200 B series ensure protection against earth faults for sinusoidal alternating currents, pulsating currents, and smooth DC residual currents. They also provide 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 IEC/EN 61008-1, 61008-2-1, 61543 (VDE 0664 10, 11, 30) and Type B DIN EN 62423 (VDE 0664-40). Their primary application areas are in commercial and industrial settings. The extensive range of accessories provides everything you need for your installation tasks. The RCCB Type B is suitable for non-linear circuits that can generate fault currents with smooth DC residual currents and various (high/low) frequencies. These components are found in electronic devices such as frequency converters. The RCCB Type B has a frequency range of 0...2 kHz for detecting the fault current and offers high system availability.
