Why Choose the ABB DS204AB630.03 RCBO?
The ABB DS204AB630.03, manufacturer type DS204 A-B63/0.03, is a high-performance four-pole Type A residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth leakage faults. As part of the proven ABB DS200 series, it combines overcurrent and residual-current protection in a single modular device for residential, commercial and industrial electrical distribution systems.
This RCBO has a 63 A rated current, B tripping characteristic and 30 mA rated residual operating current. Its Type A residual-current characteristic provides detection of sinusoidal AC and pulsating DC residual currents, while the B characteristic is suited to circuits with relatively low starting and inrush currents.
With four protected poles, a 400 V AC rated voltage and a 6 kA rated short-circuit breaking capacity, the DS204 A-B63/0.03 provides dependable circuit and residual-current protection for three-phase electrical installations while helping simplify distribution-board design and wiring.
Key Advantages
- Combines overcurrent and residual-current protection in one RCBO.
- 63 A rated current for higher-load electrical circuits.
- 30 mA residual-current sensitivity for additional protection against electric shock.

Combined Circuit and Residual-Current Protection
An RCBO combines the functions of a miniature circuit breaker and a residual-current protective device. The ABB DS204 A-B63/0.03 therefore protects circuits against overload and short-circuit currents while also detecting earth leakage currents that can create electric-shock and electrically initiated fire hazards.
The Type A residual-current characteristic enables detection of sinusoidal alternating and pulsating DC residual currents, while the B curve provides overcurrent protection suited to circuits with relatively low starting currents. Combining these protective functions in one device helps reduce component count and simplifies electrical distribution-board installation.
Typical Applications
- Three-phase electrical distribution boards.
- Residential three-phase electrical systems.
- Commercial electrical installations.
- Industrial electrical distribution systems.
- Lighting and general power circuits with relatively low inrush currents.
- Circuits requiring combined overload, short-circuit and earth leakage protection.
