F200 Type B for smooth direct current fault currents and operational safety. All-current sensitive, with a short-time delay of 10 ms, and shock current resistant up to 3 kA (5 kA for selective versions). 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 B series residual current devices ensure protection against sinusoidal alternating currents, pulsating currents, and smooth direct current fault currents to ground. They also provide fault protection (protection against indirect contact), additional protection (with IΔn ≤ 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). Applications include household, commercial, or industrial uses. The extensive range of accessories provides everything you need for your installation tasks. The Type B RCCBs are suitable for non-linear circuits that can generate fault currents with smooth direct current fault currents and various (high/low) frequencies. These components are found in electronic devices such as frequency converters. The Type B RCCBs have a frequency range of 0...2 kHz for detecting fault currents and offer high system availability.
