Why Choose the ABB DS201 B25 A100 RCBO?
The ABB DS201 B25 A100 is a compact and reliable residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase circuits against overloads, short circuits and residual earth fault currents. As part of the ABB DS200 / DS201 RCBO range, it combines residual current and overcurrent protection in a single two-module protective device for residential, commercial and industrial electrical distribution.
This RCBO provides a 25 A rated current, B tripping characteristic and 100 mA Type A residual current sensitivity. Type A residual current protection detects sinusoidal AC and pulsating DC residual currents, while the B characteristic is suited to circuits with relatively low inrush currents.
With a 1P+N configuration, 230 V AC rated voltage and 6 kA rated short-circuit breaking capacity, the DS201 B25 A100 provides combined circuit and residual current protection in a compact DIN-rail format. ABB order code 2CSR255180R2255 identifies this specific 25 A, B-curve, Type A, 100 mA version.

Combined Residual Current and Overcurrent Protection
RCBOs such as the ABB DS201 combine the functions of a miniature circuit breaker and a residual current protective device. The DS201 B25 A100 therefore protects the connected circuit against overload and short-circuit currents while also disconnecting the supply when residual current reaches the device's operating threshold.
The Type A characteristic enables detection of sinusoidal alternating and pulsating direct residual currents. Combined with its 100 mA sensitivity, B tripping characteristic and compact 1P+N construction, the DS201 B25 A100 provides coordinated protection for suitable residential, commercial and industrial electrical circuits.
Typical Applications
- Single-phase electrical distribution circuits.
- Residential and commercial electrical installations.
- Building-services circuits.
- Control and auxiliary circuits.
- Circuits supplying general electrical loads with relatively low inrush currents.
- Industrial control panels and distribution boards.
