Why Choose the ABB DDA204B630.3APR RCD Block?
The ABB DDA204B630.3APR is a four-pole Type B AP-R residual current device (RCD) block designed for assembly with compatible ABB miniature circuit breakers. Part of the ABB DDA200 RCD series, it provides comprehensive residual-current protection for demanding commercial and industrial installations containing electronic equipment and power-conversion loads.
Rated at 63 A with a rated residual operating current of 300 mA, the DDA204B630.3APR provides Type B detection for sinusoidal AC, pulsating DC and smooth DC residual currents. ABB's AP-R high-immunity characteristic combines resistance to transient disturbances with a short 10 ms intentional delay, helping minimise unwanted tripping and improve continuity of service.
The DDA204B630.3APR has a four-pole configuration and a rated voltage of 230–400 V AC, making it suitable for three-phase systems with neutral. Its 3 kA surge-current resistance further enhances immunity to impulsive leakage currents, while assembly with a compatible ABB S200 series or S300P miniature circuit breaker adds overload and short-circuit protection.
Key Advantages
- Type B residual current protection for sinusoidal AC, pulsating DC and smooth DC residual currents.
- AP-R high-immunity characteristic helps reduce unwanted tripping from transient disturbances.
- 10 ms short-time delay supports improved continuity of service.

Type B AP-R Protection for Power Electronic Loads
The ABB DDA204B630.3APR provides comprehensive residual-current detection for installations where electronic equipment can generate complex earth-fault currents. Its Type B characteristic covers sinusoidal AC, pulsating DC and smooth DC residual currents, making it particularly appropriate for power electronic equipment, frequency converters and other electronically controlled loads.
ABB's AP-R high-immunity technology combines a short 10 ms delay with 3 kA surge-current resistance to help prevent unwanted operation caused by transient leakage-current peaks. Its 300 mA operating threshold is intended for appropriate higher-threshold residual-current protection applications and does not replace 30 mA additional protection where that sensitivity is required. Overload and short-circuit protection are provided by the compatible miniature circuit breaker assembled with the RCD block.
Typical Applications
- Industrial three-phase electrical distribution systems.
- Commercial installations containing power electronic equipment.
- Variable-speed drives and frequency converter circuits.
- UPS and power conversion systems.
- Industrial machinery and automation equipment.
- Three-phase systems with neutral.
- Installations where smooth DC residual currents may occur.
- Circuits requiring 300 mA Type B residual current protection with enhanced immunity to transient disturbances.
