F200 Type B for smooth DC residual currents and operational safety, all-current sensitive, with a short delay of 10 ms, shock current resistant up to 3 kA (5 kA for selective versions). 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 areas of application are in commercial and industrial settings. The extensive range of accessories provides everything you need for your installation tasks. Type B RCCBs are suitable for non-linear circuits that can generate residual currents with smooth DC residual currents and various (high/low) frequencies. These components are found in electronic devices such as frequency converters. Type B RCCBs have a frequency range of 0 to 2 kHz for detecting residual currents and offer high system availability.
