Why Choose the ABB DDA202 AC-63/2 RCD Block?
The ABB DDA202 AC-63/2 is a robust 2-pole Type AC residual current device (RCD) block designed to provide residual-current protection when combined with compatible ABB miniature circuit breakers. As part of the ABB DDA200 RCD series, it is intended for residential, commercial and industrial electrical installations requiring detection of sinusoidal alternating earth fault currents.
This RCD block has a 2000 mA (2 A) rated residual current, providing earth leakage protection for applications where this higher residual-current threshold is specified. Its Type AC characteristic responds to sinusoidal alternating residual currents, while the DDA200 modular architecture allows residual-current protection to be combined with the overload and short-circuit protection of a compatible ABB miniature circuit breaker.
With a rated current of 63 A, a 2-pole configuration and a rated voltage of 230/400 V AC, the DDA202 AC-63/2 is suitable for higher-current electrical distribution circuits. Its compact modular construction enables straightforward installation in electrical distribution boards and control panels requiring coordinated residual-current and overcurrent protection.

Reliable Residual-Current Protection for Electrical Installations
Residual current protection helps safeguard electrical installations by detecting leakage current flowing from an electrical circuit to earth. The ABB DDA202 AC-63/2 responds to sinusoidal alternating residual currents, helping reduce risks associated with insulation faults and earth leakage in electrical distribution systems.
The DDA200 system can be coupled with ABB S200 L, S200, S200 M and S200 P miniature circuit breakers to provide combined residual-current and overcurrent protection. DDA200 blocks can also be combined with compatible ABB M200 magnetic-only circuit breakers, in which case separate thermal protection against overload currents is required.
Typical Applications
- Commercial electrical distribution systems.
- Industrial electrical distribution boards.
- Circuits requiring 2000 mA residual-current protection.
- Earth leakage and insulation fault protection applications.
- Electrical control panels and modular distribution equipment.
- Higher-current circuits requiring a 63 A RCD block.
- Combined residual-current and overcurrent protection assemblies using compatible ABB devices.
