Why Choose the ABB DS204 AC-C50/0.03 RCBO?
The ABB DS204 AC-C50/0.03 is a reliable four-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and AC residual earth-fault currents. As part of the ABB DS200 RCBO series, it combines residual-current and overcurrent protection in a single DIN-rail device for efficient electrical distribution and circuit protection.
This RCBO has a 50 A rated current, C tripping characteristic and 30 mA rated residual operating current. Its Type AC residual-current characteristic is intended for detecting sinusoidal alternating residual currents, while the integrated thermal-magnetic protection provides dependable protection against overload and short-circuit conditions.
With a 6 kA rated short-circuit breaking capacity and four-pole configuration, the DS204 AC-C50/0.03 is suitable for three-phase electrical distribution circuits requiring coordinated protection of all poles. The 50 A and 63 A DS204 versions also incorporate additional terminals for remote tripping, supporting enhanced control and protection arrangements.

Combined Residual-Current and Overcurrent Protection
RCBOs combine the functions normally provided by a residual current device and a miniature circuit breaker. This enables a single protective device to respond to earth-leakage faults as well as overload and short-circuit conditions, helping simplify distribution-board design while providing comprehensive circuit protection.
The ABB DS200 series is designed for electrical distribution applications where dependable protection and compact DIN-rail installation are required. The DS204 AC-C50/0.03 provides four-pole switching and protection, making it particularly suitable for three-phase circuits where residual-current and overcurrent protection must be integrated into one device.
Typical Applications
- Three-phase electrical distribution boards.
- Commercial and industrial electrical installations.
- Machinery and automation distribution circuits.
- Building electrical systems.
- Circuits requiring combined earth-leakage and overcurrent protection.
- DIN-rail control and distribution panels.
