Why Choose the ABB DS204MAC500.03 RCBO?
The ABB DS204MAC500.03, manufacturer type DS204 M A-C50/0.03, is a high-performance 4-pole 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 ABB DS200 M series, it combines residual current and overcurrent protection within a single DIN-rail protective device for electrical distribution systems.
This RCBO has a rated current of 50 A, a Type C tripping characteristic and a rated residual operating current of 30 mA. Its Type A residual current detection provides protection against sinusoidal AC residual currents and pulsating DC residual currents, making it suitable for circuits supplying modern electrical and electronic equipment.
With a rated voltage of 400 V AC and a rated short-circuit capacity of 10 kA, the DS204 M A-C50/0.03 is designed for demanding low-voltage distribution applications. The four protected poles allow simultaneous overcurrent protection across four conductors, while this 50 A version is also provided with additional terminals for remote tripping.
Key Advantages
- Combined residual current and overcurrent protection in one RCBO.
- 50 A rated current for higher-current distribution circuits.
- 30 mA residual current sensitivity for additional protection against electric shock.
- Type A residual current detection for AC and pulsating DC residual currents.
- Type C tripping characteristic suitable for circuits with moderate inrush currents.
- 10 kA short-circuit capacity at 400 V AC.
- Four protected poles for multi-phase electrical distribution systems.
- Additional terminals provided for remote tripping.

- 10 kA rated short-circuit capacity at 400 V AC.
- DIN-rail format for installation in electrical distribution assemblies.
Combined Residual Current and Overcurrent Protection
An RCBO combines the functions normally associated with residual current protection and miniature circuit breaker protection in a single device. The ABB DS204 M A-C50/0.03 protects circuits against overload and short-circuit currents while also detecting potentially hazardous earth leakage currents, helping protect people, wiring and connected equipment.
The Type A residual current characteristic enables detection of sinusoidal alternating and pulsating DC residual currents, while the C-curve overcurrent characteristic is suited to circuits where normal equipment operation can produce moderate starting or inrush currents. This combination makes the DS204 M suitable for a broad range of commercial, industrial and building electrical distribution applications.
Typical Applications
- Commercial and industrial electrical distribution boards.
- Three-phase and multi-pole final circuits.
- Machinery and industrial equipment supplies.
- Circuits containing electronic equipment and power supplies.
- Building electrical installations requiring 30 mA residual current protection.
- Distribution circuits requiring combined overload, short-circuit and earth leakage protection.
