Why Choose the ABB DS203 AC-C16/0.03 RCBO?
The ABB DS203 AC-C16/0.03 is a dependable 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 is designed to detect sinusoidal alternating residual currents, while its C tripping characteristic is suitable for general-purpose circuits and equipment with moderate starting currents. Combining residual current and miniature circuit-breaker functions in one device helps simplify distribution-board design and provides coordinated protection for individual circuits.
With a rated current of 16 A, a rated residual operating current of 30 mA and a rated short-circuit breaking capacity of 6 kA, the DS203 AC-C16/0.03 provides reliable protection for three-phase circuits. Its three-pole configuration makes it well suited to commercial distribution systems, industrial control panels and machinery applications.

Reliable Protection for Three-Phase Circuits
RCBOs combine residual current protection with overload and short-circuit protection in a single device. This enables an individual electrical circuit to be protected against several common electrical fault conditions while reducing the need for separate residual current and miniature circuit-breaker components.
The DS203 AC-C16/0.03 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 combination of functions makes it suitable for a broad range of commercial and industrial three-phase distribution applications.
Typical Applications
- Commercial electrical distribution boards.
- Industrial three-phase circuits.
- Machinery and automation control panels.
- Lighting and general-purpose electrical circuits.
- Equipment with moderate starting currents.
- Installations requiring combined residual current and overcurrent protection.
