Why Choose the ABB DDA804 A-100/0.03 AP-R RCD Block?
The ABB DDA804 A-100/0.03 AP-R is a high-immunity Type A residual current device (RCD) block designed for assembly with compatible ABB S800 series miniature circuit breakers. With a rated current of 100 A, four-pole configuration and 30 mA rated residual operating current, it provides residual-current protection for commercial and industrial electrical installations.
As part of the ABB DDA800 AP-R series, this RCD block detects sinusoidal alternating and pulsating DC residual currents while providing enhanced resistance to unwanted tripping. The AP-R characteristic combines high immunity to transient disturbances with a short intentional delay, helping improve continuity of service in installations where conventional instantaneous RCDs may be susceptible to nuisance operation.
The DDA804 A-100/0.03 AP-R is rated for 230/400, 240/415 and 400/690 V AC systems at 50–60 Hz. Its 30 mA sensitivity provides additional protection against direct contact, while the four-pole configuration makes it suitable for three-phase systems with neutral. When assembled with a compatible S800 MCB, it provides residual-current protection alongside overload and short-circuit protection.

High-Immunity Residual-Current Protection
Residual current device blocks monitor electrical circuits for current unintentionally flowing to earth. The ABB DDA804 A-100/0.03 AP-R provides Type A detection for sinusoidal alternating and pulsating DC residual currents, while its 30 mA sensitivity provides additional protection against direct contact as part of a correctly designed electrical installation.
The AP-R high-immunity characteristic is specifically designed to improve resistance to unwanted tripping caused by transient disturbances. With enhanced surge-current resistance and a short operating delay, it provides a practical balance between electrical safety and continuity of service. When assembled with a compatible ABB S800 MCB, it complements overload and short-circuit protection with high-immunity residual-current protection.
Typical Applications
- Industrial electrical distribution boards.
- Commercial power distribution systems.
- Three-phase circuits with neutral conductors.
- Machine and automation control panels.
- Installations susceptible to transient disturbances and nuisance RCD tripping.
- Industrial plant and infrastructure electrical systems.
