Why Choose the ABB DS202 AC-B25/0.03 RCBO?
The ABB DS202 AC-B25/0.03 is a two-pole Type AC residual current circuit breaker with overcurrent protection (RCBO) that combines residual-current, overload and short-circuit protection within a single modular device. Part of ABB’s DS200 RCBO series, it is designed for residential, commercial and industrial electrical installations requiring dedicated protection and isolation of individual circuits.
With a rated current of 25 A, a B-curve tripping characteristic and a rated residual operating current of 30 mA, the DS202 AC-B25/0.03 protects against overloads and short circuits while detecting sinusoidal alternating earth-fault currents. The 30 mA residual-current sensitivity provides additional protection against direct contact as well as protection against the effects of indirect contact.
The DS202 AC-B25/0.03 has a rated short-circuit breaking capacity of 6 kA and a two-pole configuration. By combining overcurrent and residual-current protection in one DIN-rail device, it provides effective individual circuit fault isolation while reducing the need for separate MCB and RCCB protection components.
Key Advantages
- Combined RCBO protection against residual current, overload and short circuit in one device.
- 30 mA residual-current sensitivity provides additional protection against electric shock.
- 25 A rated current for suitable residential, commercial and industrial final circuits.
- B-curve characteristic is suited to circuits with relatively low normal starting and inrush currents.
- Type AC residual-current detection responds to sinusoidal alternating earth-fault currents.
- 6 kA rated short-circuit breaking capacity.
- Two-pole configuration provides protection and isolation for both poles.

Combined Residual-Current and Overcurrent Protection
An RCBO combines the functions of residual-current protection and overcurrent protection within a single protective device. The ABB DS202 AC-B25/0.03 protects its circuit against sinusoidal alternating earth-fault currents as well as overload and short-circuit conditions, enabling individual circuit protection without requiring separate RCCB and MCB devices for these functions.
Its Type AC residual-current characteristic is designed for sinusoidal alternating fault currents, while the B-curve 25 A overcurrent characteristic is suited to circuits with relatively low normal inrush currents. Together with 30 mA residual-current sensitivity and a 6 kA short-circuit breaking capacity, the DS202 AC-B25/0.03 provides comprehensive protection for suitable final circuits.
Typical Applications
- Residential electrical distribution boards.
- Commercial electrical distribution systems.
- Industrial electrical distribution and control systems.
- Final circuits requiring 25 A B-curve overcurrent protection.
- Circuits requiring 30 mA additional residual-current protection.
- Electrical installations requiring dedicated two-pole RCBO protection and individual fault isolation.
