[8012542020325] DDA204 B-40/0,03 AP-R - RCD Block

The FI block (RCU) is for customer assembly with automatic switches in the S200 series. The resulting RCD / LS combinations (RCBOs) offer personal and property protection as well as protection against electrically lit fires in accordance with DIN VDE 0100-410 and DIN VDE 0100-530. They guarantee protection of single-phase circuits against overload and short-circuit currents, protection against sinusoidal alternating currents and pulsating currents with smooth DC residual currents up to 10 mA to the ground and smooth DC residual currents in the frequency range 0 ... 2 kHz. 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 comply with the product standards IEC / EN 61009-1 (VDE 0664-20) Appendix G, DIN EN 62423 (VDE 0664-40). Areas of application are mainly commercial and industrial applications. The comprehensive range of accessories gives you everything you need for your installation tasks. The optimal compromise between safety and operational continuity provides high system availability thanks to the interference immunity with surge current resistance (surge current from 8/20? S) = 3,000 A against unintentional tripping and 10 ms short delay.
