Why Choose the ABB DS203NCC13A30 RCBO?
The ABB DS203NCC13A30 is a compact 3P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect three-phase end-user circuits against overloads, short circuits and residual earth-fault currents. Part of the ABB DS203NC series, it combines residual-current and overcurrent protection within a single four-module device for efficient commercial and industrial electrical distribution.
This RCBO has a rated current of 13 A, a Type C tripping characteristic and a rated residual operating current of 30 mA. Its Type A residual-current characteristic detects sinusoidal alternating and pulsating DC residual currents, making it suitable for modern electrical circuits where these residual-current waveforms may occur.
With a rated voltage of 415 V AC and a rated short-circuit breaking capacity of 6 kA, the DS203NC C13 A30 provides integrated protection for three-phase plus neutral circuits. Its 30 mA residual-current sensitivity supports protection against indirect contact and additional protection against direct contact in suitable installations.
Key Advantages
- Combined residual-current, overload and short-circuit protection in one device.
- 13 A rated current with Type C tripping characteristic.

Reliable Type A Protection for Three-Phase Circuits
The ABB DS203NCC13A30 combines overcurrent and residual-current protection within one modular device. Its overcurrent function protects against overload and short-circuit currents, while its Type A residual-current function responds to sinusoidal alternating and pulsating DC earth-fault currents that can occur in modern electrical installations.
With a residual-current sensitivity of 30 mA, the DS203NCC13A30 provides protection against indirect contact and additional protection against direct contact where applicable. Its Type C characteristic is suited to appropriate circuits where moderate starting or inrush currents can occur, while the compact four-module format helps conserve valuable distribution-board space.
Typical Applications
- Three-phase end-user electrical circuits.
- Commercial and industrial distribution boards.
- Electrical control panels and switchboards.
- Circuits with moderate starting or inrush currents.
- Circuits containing equipment capable of producing pulsating DC residual currents.
- Three-phase circuits requiring combined Type C overcurrent and Type A residual-current protection.
