Why Choose the ABB DDA203A630.5AE Residual Current Device Block?
The ABB DDA203A630.5AE, manufacturer type DDA203 A-63/0.5 AE, is a 3-pole Type A residual current device (RCD) block from the ABB DDA200 range. Designed for combination with compatible ABB miniature circuit breakers, it provides residual-current protection for suitable three-phase commercial and industrial electrical distribution circuits.
The DDA203 A-63/0.5 AE is designed to detect both sinusoidal AC and pulsating DC residual currents. This Type A characteristic provides broader residual-current detection than Type AC devices and supports applications containing modern electrical and electronic equipment capable of producing pulsating DC earth-leakage currents.
With a rated current of 63 A, a rated residual operating current of 500 mA and a 3-pole configuration, the DDA203A630.5AE is suited to applications requiring this higher residual-current threshold. When correctly assembled with a compatible ABB miniature circuit breaker, the resulting combination provides residual-current protection together with overload and short-circuit protection.
Key Advantages
- Type A residual-current detection for sinusoidal AC and pulsating DC residual currents.
- 63 A rated current for higher-current compatible circuits.
- 500 mA rated residual operating current for applications specifying this earth-leakage threshold.
- 3-pole configuration for suitable three-phase circuit arrangements.
- Suitable for installations incorporating electrical and electronic loads.
- Designed for combination with compatible ABB miniature circuit breakers.
- Part of ABB's modular DDA200 residual current device block range.
Key Features
- ABB DDA200 residual current device block series.
- Type A residual-current characteristic.
- AE variant.
- 63 A rated current.
- 500 mA rated residual operating current.
- 3 poles.
- Detection of sinusoidal AC and pulsating DC residual currents.
- Modular construction for combination with compatible ABB miniature circuit breakers.
Reliable Type A Protection for Three-Phase Circuits
Type A residual-current protection responds to sinusoidal alternating residual currents as well as pulsating DC residual currents. This makes the ABB DDA203 A-63/0.5 AE suitable for compatible electrical installations where electronic equipment or rectifier-based loads can produce residual-current waveforms requiring Type A detection.
The 500 mA residual-current operating threshold is intended for applications specifically designed around a higher earth-leakage trip level rather than sensitive 30 mA additional protection. The modular DDA200 construction allows the RCD block to be paired with a compatible ABB miniature circuit breaker to provide coordinated residual-current, overload and short-circuit protection.
Typical Applications
- Three-phase commercial electrical distribution systems.
- Industrial electrical installations.
- Distribution boards and sub-distribution panels.
- Electrical control and automation panels.
- Circuits containing electronic equipment capable of producing pulsating DC residual currents.
- Circuits requiring 500 mA Type A residual-current protection.
- Assemblies using compatible ABB miniature circuit breakers.
