Why Choose the ABB DS202 A-B40/0.03 RCBO?
The ABB DS202 A-B40/0.03 is a two-pole Type A residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and residual earth fault currents. As part of the ABB DS200 / DSH200 RCBO range, it provides comprehensive circuit protection in a factory-assembled DIN-rail device for commercial and industrial electrical distribution systems.
With a rated current of 40 A, a rated residual operating current of 30 mA and a 6 kA rated short-circuit breaking capacity according to IEC/EN 61009-1, the DS202 A-B40/0.03 combines overcurrent and residual-current protection in one unit. Its Type A residual-current characteristic provides protection against sinusoidal AC and pulsating DC residual currents encountered with a wide range of modern electrical equipment.
The B tripping characteristic makes this RCBO suitable for circuits with relatively low prospective inrush currents, including many commercial and industrial distribution applications. Its two-pole configuration provides switching and overcurrent protection across both poles, while the integrated test pushbutton enables periodic verification of the residual-current protection function.

Reliable Combined Circuit and Residual-Current Protection
An RCBO combines the protective functions of a miniature circuit breaker and a residual current device in a single assembly. The ABB DS202 A-B40/0.03 therefore protects the connected circuit against overload and short-circuit currents while monitoring for residual earth fault currents that could present an electric-shock or installation hazard.
The Type A residual-current characteristic enables the device to respond to sinusoidal AC and pulsating DC residual currents. Combined with its B overcurrent characteristic, two protected poles and 30 mA sensitivity, this makes the DS202 A-B40/0.03 suitable for a broad range of commercial and industrial distribution circuits requiring coordinated residual-current and overcurrent protection.
Typical Applications
- Commercial electrical distribution systems.
- Industrial electrical distribution boards.
- Final circuits requiring 40 A overcurrent protection.
- Industrial control panels and switchboards.
- Commercial equipment and electrical installations.
- Circuits requiring Type A 30 mA residual-current protection.
