Why Choose the ABB DS202CRB40A30 RCBO?
The ABB DS202CRB40A30 is a compact and dependable 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and residual earth fault currents. Part of the ABB DS200 / DSH200 RCBO range, it combines overcurrent and residual-current protection in a single modular device for electrical distribution circuits.
With a rated current of 40 A, B tripping characteristic and 30 mA rated residual operating current, the DS202CR B40 A30 provides coordinated protection for final circuits and connected equipment. Its Type A residual-current characteristic detects sinusoidal AC residual currents as well as pulsating DC residual currents, making it suitable for modern electrical installations containing electronic loads.
The 2-pole configuration provides switching of both circuit conductors, while the B characteristic is suitable for circuits with relatively low inrush currents. Its 30 mA sensitivity supports additional protection against electric shock, making the DS202CRB40A30 a practical protective device for commercial, industrial and other professional electrical distribution applications.
Key Advantages
- Combined residual-current, overload and short-circuit protection in one modular device.
- 40 A rated current for higher-current electrical circuits.

Reliable Combined Circuit and Residual-Current Protection
An RCBO combines the functions of a miniature circuit breaker and a residual-current protective device within a single unit. The ABB DS202CRB40A30 therefore protects connected circuits against overload and short-circuit currents while also detecting leakage to earth caused by insulation faults or other electrical problems.
The Type A characteristic enables the RCBO to respond to sinusoidal alternating residual currents and pulsating DC residual currents. This makes Type A protection particularly relevant to modern installations where electronic power supplies, controls and other semiconductor-based equipment can produce residual-current waveforms requiring more than conventional AC-only detection.
Typical Applications
- Electrical final circuits requiring 30 mA residual-current protection.
- Commercial and industrial distribution boards.
- Electrical control and automation panels.
- Lighting, heating and other loads with relatively low inrush currents.
- Circuits supplying modern electronic equipment.
- Applications requiring combined overcurrent and Type A residual-current protection.
