ABB 2CSB802201R5000 DDA802AS-100/1 RCCB 100 A 1 A 400 V

The FI-Block (RCU) is for customer-side mounting with high-performance circuit breakers of the S800 series. The resulting FI/LS combinations (RCBOs) provide property protection and protection against electrically ignited fires. They protect 2P, 3P or 4P circuits against overload and short-circuit currents, protect against sinusoidal AC currents and pulsating currents with smooth DC fault current up to 6 mA against earth. Fault protection (protection in case of indirect contact), additional protection (with IΔn ≤ 30 mA) and fire protection (with I∆n ≤ 300 mA). They comply with the product standard IEC/EN 60947-2. Industrial applications. The extensive range of accessories offers you everything that you need WAS for your installation tasks.
Optimum compromise between safety and operating continuity thanks to the immunity to interference against accidental triggering with surge current stability (surge current form 8/20 μs) = 5000 A. Selectivity with a downstream device with a lower rated fault current of, for example, 30 mA.
