Residual current circuit breakers (RCCBs) of the F400 Type B series for smooth DC residual currents and operational safety, AC/DC sensitive, 10 ms short-time delayed, surge current resistant to 3 kA.
Residual current protective devices (RCCBs) offer protection for people 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 F400 B series ensure protection against sinusoidal alternating currents, pulsating currents and smooth DC residual currents to earth. As well as fault protection (protection against indirect contact), additional protection (with I¿n = 30 mA) and fire protection (with I¿n = 300 mA). They meet the 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). Areas of application are mainly in commercial and industrial applications. The range of accessories offers you everything you need for your installation tasks on the Smissline TP plug-in base system. The RCCB type B is suitable for non-linear circuits that can generate fault currents with smooth DC fault currents and with a wide variety of (high/) frequencies. These components are found in electronic equipment such as frequency converters. Contact is made directly via the Smissline TP plug-in base system.
