Why Choose the ABB DDA802 A-63/0.03 Residual Current Device?
The ABB DDA802 A-63/0.03 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 a modular solution for adding earth-leakage protection to low-voltage electrical distribution circuits.
Featuring Type A residual-current detection, the DDA802 A-63/0.03 is designed to detect sinusoidal alternating residual currents as well as pulsating DC 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 2-pole configuration, the DDA802 A-63/0.03 is suitable for compatible two-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 A Residual-Current Protection for S800 Circuit Breaker Assemblies
Type A residual current devices respond to sinusoidal alternating residual currents and pulsating DC residual currents, providing broader residual-current detection than Type AC devices. This makes them suitable for circuits containing electrical and electronic equipment capable of producing pulsating DC fault-current components.
The ABB DDA802 A-63/0.03 adds this residual-current functionality to a compatible ABB S800 circuit breaker. Its 63 A current rating, 30 mA residual operating threshold and Type A characteristic provide a practical solution for two-pole distribution circuits requiring sensitive earth-leakage protection.
