Why Choose the ABB DS301C B6 A30 RCBO?
The ABB DS301C B6 A30 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and residual earth fault currents. As part of the ABB DS301C RCBO series, it combines circuit and residual-current protection within a space-saving single-module device for residential, commercial and industrial electrical installations.
This RCBO features Type A residual-current protection, enabling it to detect both sinusoidal alternating and pulsating DC residual currents. Its 30 mA rated residual operating current provides additional protection against electric shock, while the voltage-independent electromechanical operating principle supports reliable residual-current protection without dependence on the supply voltage.
With a rated current of 6 A, B tripping characteristic and 6 kA rated short-circuit breaking capacity, the DS301C B6 A30 is particularly suitable for lower-current final circuits with relatively low inrush currents. At only 17.6 mm wide, its single-module format helps maximise available DIN-rail space in compact distribution boards.
Key Advantages
- Combined residual-current and overcurrent protection in one compact RCBO.
- 6 A rated current with B-curve overcurrent protection.
- 30 mA residual-current sensitivity for additional protection against electric shock.
- Type A protection detects sinusoidal AC and pulsating DC residual currents.
- 6 kA short-circuit breaking capacity.
- Voltage-independent electromechanical residual-current operation.
- Compact 17.6 mm single-module design saves valuable DIN-rail space.

- 6 A rated current.
- B tripping characteristic.
- Type A residual-current protection.
- 30 mA rated residual operating current.
- 6 kA rated short-circuit breaking capacity.
- 1P+N pole configuration.

- Voltage-independent electromechanical operation.
- Compact one-module DIN-rail format.
Compact Type A Protection for Single-Phase Circuits
An RCBO combines miniature circuit breaker and residual-current protection functions within a single device. The ABB DS301C B6 A30 protects connected circuits against overload and short-circuit currents while also detecting sinusoidal alternating and pulsating DC residual earth fault currents, making its Type A protection suitable for a broader range of modern electrical loads than Type AC devices.
The DS301C series uses a voltage-independent electromechanical design and occupies only one standard DIN-rail module. This compact architecture helps reduce distribution-board space requirements while allowing individual final circuits to receive dedicated overcurrent and residual-current protection, supporting continuity of service on unaffected circuits if a fault occurs elsewhere.
Typical Applications
- Residential electrical distribution boards.
- Commercial building final circuits.
- Lighting and other lower-current circuits.
- Circuits supplying electronic equipment capable of producing pulsating DC residual currents.
- Building services distribution systems.
- Industrial control and distribution panels.
