[8012542926207] DDA804 A S-63/0,3 - RCD Block

The FI block (RCU) is for customer collection with high-performance switches in the S800 series. The resulting RCD / LS combinations (RCBOs) offer property protection and protection against electrically ignited fires. They guarantee protection of 2P, 3P or 4P circuits against overload and short circuit currents, protection against sinusoidal alternating currents and pulsating currents with smooth direct fault currents up to 6 mA to the ground. As well as fault protection (protection against indirect contact) and fire protection (with I? N? 300 mA). They comply with the product standard IEC / EN 60947-2. Areas of application are industrial applications. The comprehensive range of accessories gives you everything you need for your installation tasks. Optimal compromise between safety and operational continuity thanks to the interference immunity against accidental tripping with surge current resistance (surge current from 8/20? S) = 5000 A. Selectivity with downstream units with a lower nominal residual current of e.g. 30 mA (see selectivity tables in catalog chapter technology).
