Why Choose the ABB DDA804AC-63/0.3 RCD Block?
The ABB DDA804AC-63/0.3 is a reliable Type AC residual current device (RCD) block designed for on-site assembly with compatible ABB S800 miniature circuit-breakers. As part of the ABB DDA800 series, it provides residual current protection against sinusoidal alternating earth fault currents while enabling the associated S800 MCB to provide overload and short-circuit protection.
This instantaneous Type AC RCD block is intended for commercial and industrial electrical installations requiring dependable earth leakage protection. When correctly combined with a compatible ABB S800 MCB, it creates an integrated protective assembly for low-voltage distribution circuits while retaining the high-performance characteristics of the S800 system.
With a rated current of 63 A, a four-pole configuration and a rated residual operating current of 300 mA, the DDA804AC-63/0.3 is well suited to suitable three-phase distribution systems requiring earth fault and leakage protection. It is designed for assembly with compatible ABB S800 series MCBs up to 63 A.

Reliable Type AC Residual Current Protection
Residual current protection monitors leakage current flowing to earth and disconnects the protected circuit when the residual current reaches the device's operating threshold. The 300 mA sensitivity of the ABB DDA804AC-63/0.3 makes it suitable for appropriate earth fault and leakage protection applications in commercial and industrial electrical distribution systems.
As a Type AC device, the DDA804AC-63/0.3 responds to sinusoidal alternating residual currents. When assembled with a compatible ABB S800 miniature circuit-breaker, the RCD block adds residual current protection while the MCB provides the associated overload and short-circuit protection, creating a compact protective solution for demanding distribution applications.
Typical Applications
- Three-phase commercial electrical distribution systems.
- Industrial electrical installations.
- Distribution boards using compatible ABB S800 miniature circuit-breakers.
- Circuits requiring 300 mA residual current protection.
- Applications requiring protection against sinusoidal AC earth fault currents.
- Low-voltage distribution circuits requiring combined residual current and overcurrent protection.
