F200 Type B+ for smooth DC residual currents and advanced, preventive fire protection, AC/DC sensitive, 10 ms short-time delayed, surge current resistant 3 kA, residual current circuit breakers (RCCBs) offer personal and material protection as well as protection against electrically ignited fires in accordance with DIN0100-410 and DIN0100-530. The residual current circuit breakers of the F200 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 RCDs type A IEC/EN 61008-1, 61008-2-1, 61543 (VDE 0664 10, 11, 30) and for type B+ DIN0664-400. Areas of application are mainly in commercial and industrial applications. The extensive range of accessories offers you everything you need for your installation tasks. The RCCB type B+ detect smooth DC residual currents, react earlier than the RCCB type B with max. 420 mA and have a frequency range of 0 ... 20 kHz for detecting the residual current. They therefore offer advanced, preventive fire protection (extended fire protection according to DIN0100-530) for e.g. fire-prone premises and commercial units.
