Why Choose the ABB DDA202 AC-40/0.1 RCD Block?
The ABB DDA202 AC-40/0.1, order code 2CSB202001R2400, is a compact 2-pole residual current device (RCD) block designed for coupling with compatible ABB miniature circuit breakers to provide residual current protection in low-voltage electrical installations. As part of the ABB DDA200 RCD series, it is designed for residential, commercial and industrial applications requiring reliable detection of sinusoidal alternating residual currents.
This Type AC RCD block has a 40 A rated current and 100 mA rated residual operating current. When coupled with a compatible ABB miniature circuit breaker, the DDA200 system combines residual current protection with the overcurrent and short-circuit protection provided by the associated circuit breaker.
With a 230/400 V AC rated voltage, 50/60 Hz frequency and instantaneous operating characteristic, the DDA202 AC-40/0.1 provides a modular solution for electrical distribution boards. Its compact DIN rail format integrates with compatible ABB System pro M compact protection devices for professional panel building and electrical distribution applications.

Reliable Residual Current Protection for Electrical Installations
Residual current devices detect current flowing through an unintended path to earth and disconnect the protected circuit when the residual current reaches the device's operating threshold. The ABB DDA202 AC-40/0.1 is a Type AC device designed to respond to sinusoidal alternating residual currents, with a rated residual operating current of 100 mA.
The DDA200 series is designed for coupling with compatible ABB miniature circuit breakers, including devices from the S200 family, creating a combined protection assembly. The RCD block provides residual current detection while the associated circuit breaker provides the required overcurrent and short-circuit protection.
