Why Choose the ABB DDA803 AC-63/0.03 Residual Current Device?
The ABB DDA803 AC-63/0.03 is a 3-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 a modular solution for adding earth-leakage protection to three-pole low-voltage electrical distribution circuits.
Featuring Type AC residual-current detection, the DDA803 AC-63/0.03 is designed to detect sinusoidal alternating residual currents. Its rated residual operating current of 30 mA provides sensitive residual-current protection for applications requiring this operating threshold.
With a rated current of 63 A and a 3-pole configuration, the DDA803 AC-63/0.03 is suitable for compatible three-pole ABB S800 circuit-breaker assemblies. Its modular construction supports integration into professional electrical distribution boards and control panels requiring combined overcurrent and residual-current protection.

Type AC 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 residual-current protection within the electrical installation.
The ABB DDA803 AC-63/0.03 adds this functionality to a compatible ABB S800 circuit breaker. Its 63 A current rating, 30 mA residual operating threshold and Type AC characteristic provide a practical solution for three-pole distribution circuits requiring sensitive detection of sinusoidal AC residual currents.
