Why Choose the ABB DS202CRMB20A30 RCBO?
The ABB DS202CRMB20A30 is a 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to combine overload, short-circuit and residual-current protection within a single modular protective device. Part of the ABB DS200 / DSH200 RCBO range, the DS202CR M B20 A30 provides coordinated circuit and earth-fault protection for professional electrical distribution applications.
With a rated current of 20 A, B tripping characteristic and 30 mA rated residual operating current, this RCBO provides combined protection for electrical final circuits and connected equipment. Its Type A residual-current characteristic detects sinusoidal AC residual currents and pulsating DC residual currents, making it suitable for many modern circuits containing electronic equipment.
The 2-pole configuration provides switching of both circuit conductors, while the B characteristic is suitable for circuits with relatively low starting or inrush currents. Its 30 mA residual-current sensitivity supports additional protection against electric shock, making the DS202CRMB20A30 a practical solution where combined 20 A overcurrent and Type A residual-current protection is required.
Key Advantages
- Combined residual-current, overload and short-circuit protection in one modular device.
- 20 A rated current for electrical final circuits.

Reliable Combined Circuit and Residual-Current Protection
An RCBO combines overcurrent and residual-current protection in one device, allowing the ABB DS202CRMB20A30 to respond to overloads and short circuits while also detecting leakage currents to earth. Its 30 mA residual-current sensitivity supports additional protection against electric shock while providing earth-fault protection for the connected circuit.
The Type A characteristic enables the DS202CRMB20A30 to detect sinusoidal alternating residual currents and pulsating DC residual currents. This capability makes Type A protection particularly relevant to modern installations containing electronic power supplies, controls and other equipment capable of producing pulsating DC residual-current components.
