Why Choose the ABB DDA802 A-100/0.03 AP-R RCD Block?
The ABB DDA802 A-100/0.03 AP-R is a high-immunity Type A residual current device (RCD) block designed for assembly with compatible ABB S800 miniature circuit-breakers. As part of the ABB DDA800 series, it provides residual current protection for people and electrical installations while combining effectively with an S800 MCB to provide comprehensive residual current, overload and short-circuit protection.
The AP-R high-immunity operating characteristic provides increased resistance to unwanted tripping, helping achieve an effective balance between electrical safety and continuity of service. As a Type A device, the DDA802 detects sinusoidal alternating residual currents and pulsating DC residual currents, making it suitable for a wide range of modern commercial and industrial electrical loads.
With a rated current of 100 A, two-pole configuration and a rated residual operating current of 30 mA, the DDA802 A-100/0.03 AP-R provides additional protection against direct contact as well as protection against indirect contact. It is designed for on-site assembly with compatible ABB S800 MCBs up to 100 A.

High-Immunity Residual Current Protection
Residual current protection detects leakage currents flowing to earth and disconnects the protected circuit when the residual current reaches the device's operating threshold. With its 30 mA sensitivity, the ABB DDA802 A-100/0.03 AP-R provides protection against indirect contact and additional protection against direct contact when correctly combined with a compatible S800 miniature circuit-breaker.
The AP-R high-immunity design provides enhanced resistance to unwanted tripping caused by transient disturbances while retaining the protective characteristics of a Type A RCD. This makes the DDA800 AP-R range particularly useful in commercial and industrial installations where both personnel protection and continuity of electrical service are important.
Typical Applications
- Commercial electrical distribution systems.
- Industrial electrical installations.
- Distribution boards using ABB S800 miniature circuit-breakers.
- Circuits requiring 30 mA additional residual current protection.
- Installations containing equipment capable of producing pulsating DC residual currents.
- Applications where resistance to unwanted RCD tripping is important.
