Why Choose the ABB DS203 AC-C63/0.03 RCBO?
The ABB DS203 AC-C63/0.03 is a high-current 3-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth fault currents. As part of the ABB DS200 RCBO series, it integrates residual current and overcurrent protection in a single DIN rail-mounted device for commercial and industrial electrical installations.
This AC Type RCBO detects sinusoidal alternating residual currents, while its C tripping characteristic is suited to general-purpose circuits and equipment with moderate starting currents. Combining residual current and miniature circuit-breaker functions within one protective device helps simplify distribution-board design while providing dedicated protection for individual three-phase circuits.
With a rated current of 63 A, a rated residual operating current of 30 mA, a rated voltage of 400 V AC and a rated short-circuit breaking capacity of 6 kA, the DS203 AC-C63/0.03 provides comprehensive protection for demanding three-phase circuits. This 63 A version also includes additional terminals for remote tripping, supporting integration into electrical protection and control systems.

Reliable Protection for Three-Phase Circuits
RCBOs combine residual current protection with overload and short-circuit protection in a single device. This enables individual electrical circuits to receive coordinated protection against several common electrical fault conditions while reducing the need for separate residual current and overcurrent protective devices.
The DS203 AC-C63/0.03 uses an AC Type residual current characteristic for sinusoidal alternating earth fault currents and a C tripping characteristic for circuits with moderate starting currents. Its 30 mA residual current sensitivity also provides additional protection against direct contact, making it a practical protective solution for commercial and industrial three-phase distribution systems.
Typical Applications
- Commercial electrical distribution boards.
- Industrial three-phase distribution circuits.
- Machinery and automation control panels.
- Higher-current general-purpose circuits.
- Equipment with moderate starting currents.
- Systems requiring remote tripping capability.
- Installations requiring combined residual current and overcurrent protection.
