Description

  • The ABB 2CSB203201R4630 is part of the DDA200 Series, a Residual Current Device (RCD) block designed for assembly with MCBs (Miniature Circuit Breakers) from the S200 series. This RCD block is engineered to provide essential protection against the effects of sinusoidal alternating and direct pulsating earth fault currents, ensuring the safety of electrical installations.


  • One of the key features of the DDA200 Series RCD block is its intentional tripping delay. This feature is designed to enable selectivity with downstream instantaneous devices. Selectivity is crucial for electrical protection, allowing the closest device to the fault to trip while preserving the operation of other devices further downstream. This selective action minimizes disruptions and ensures that only the affected part of the circuit is isolated during a fault condition.


  • The ABB DDA200 Series RCD block is suitable for a wide range of applications where precise and selective protection against earth fault currents is required to guarantee the safe and reliable operation of electrical systems.
