Why Choose the ABB DDA802 AC-63/0.3 Residual Current Device?
The ABB DDA802 AC-63/0.3 is a 2-pole residual current device (RCD) block designed to provide residual-current protection when combined with a compatible ABB S800 series miniature circuit breaker. It provides an effective solution for adding earth-leakage protection to low-voltage electrical distribution circuits.
Featuring Type AC residual-current detection, the DDA802 AC-63/0.3 is intended to detect sinusoidal alternating residual currents. Its rated residual operating current of 300 mA makes it suitable for applications where residual-current protection at this sensitivity is required.
With a rated current of 63 A and a 2-pole configuration, the DDA802 AC-63/0.3 provides a practical residual-current protection solution for compatible two-pole ABB S800 circuit-breaker assemblies. The modular design supports integration into professional electrical distribution boards and control panels.

Residual-Current Protection for S800 Circuit Breaker Assemblies
Residual current devices detect current imbalance caused by leakage from the protected circuit towards earth. When the residual current reaches the device operating threshold, the protective assembly disconnects the circuit, helping provide the required residual-current protection within the electrical installation.
The ABB DDA802 AC-63/0.3 is designed to add this functionality to a compatible ABB S800 circuit breaker. Its 63 A current rating, 300 mA residual operating threshold and Type AC characteristic make it suitable for two-pole distribution applications requiring detection of sinusoidal AC residual currents.
Typical Applications
- Low-voltage electrical distribution boards.
- Commercial and industrial electrical installations.
- Two-pole circuits requiring residual-current protection.
- ABB S800 circuit-breaker assemblies.
- Distribution circuits requiring 300 mA residual-current sensitivity.
- Applications requiring Type AC residual-current detection.
