ABB 2CSB204592R1400 RCCB RCD (all types of current) 40 A

DDA200 type B AP-R for smooth DC fault currents
All current sensitive, 10 ms short time delayed, 3 kA surge proof
The FI block (RCU) is for customer-facing installation with circuit breakers of the S200 series. The following FI/LS combinations (RCBOs) provide personal and property protection as well as protection against electrically ignited fires according to DIN VDE 0100-410 and DIN VDE 0100-530. They provide protection from overload and short-circuit currents of 1P+N, 2P, 3P, 3P+N or 4P circuits, protection from sinusoidal AC currents and pulsating currents with a smooth DC fault current share of up to 10 mA against earth, as well as smooth DC fault currents in the frequency range of 0...1 kHz. Fault protection (protection in case of indirect contact), additional protection (with IΔn ≤ 30 mA) and fire protection (with IΔn ≤ 300 mA).
It complies with the product standards IEC/EN 61009-1 (VDE 0664-20) Annex G, IEC/EN 61009-2-1, DIN EN 62423 (VDE 0664-40). They are mainly used in commercial and industrial applications. The extensive range of accessories offers you everything that you need WAS for your installation tasks.
Optimal compromise between safety and operating continuity offers a high system availability, thanks to the immunity with surge current stability (surge current form 8/20 μs) = 3,000 A against unwanted triggering and 10 ms short time delay.
