Why Choose the ABB DDA204 AC S-63/0.3 RCD Block?
The ABB DDA204 AC S-63/0.3 is a four-pole Type AC selective residual current device (RCD) block designed for assembly with compatible ABB miniature circuit breakers. As part of the proven ABB DDA200 RCD series, it provides protection against sinusoidal alternating earth fault currents in commercial and industrial electrical installations.
The selective S operating characteristic incorporates an intentional tripping delay, enabling selectivity with instantaneous residual current protection devices installed downstream. This helps isolate an earth fault at the appropriate downstream circuit while improving continuity of supply elsewhere in the electrical installation.
With a rated current of 63 A, rated residual operating current of 300 mA and a four-pole configuration, the DDA204 AC S-63/0.3 is designed for 230/400 V AC systems. It can be assembled with compatible ABB S200 series miniature circuit breakers to provide coordinated overcurrent and residual current protection.

Selective Residual Current Protection for Electrical Distribution
The ABB DDA204 AC S-63/0.3 is designed to detect sinusoidal alternating earth fault currents while incorporating an intentional tripping delay. This selective operating characteristic allows coordination with instantaneous residual current devices installed downstream, helping ensure that the protective device closest to a fault operates first.
The DDA200 series is designed to be combined with compatible ABB S200 series miniature circuit breakers, allowing residual current, overload and short-circuit protection to be incorporated into a coordinated modular protection system. This combination makes the DDA204 AC S-63/0.3 particularly suitable for distribution systems where selective earth fault protection and continuity of service are important.
Typical Applications
- Commercial electrical distribution systems.
- Industrial electrical installations.
- Three-phase distribution boards.
- Circuits requiring selective residual current protection.
- Upstream protection coordinated with instantaneous downstream RCDs.
- Electrical panels using compatible ABB S200 series miniature circuit breakers.
