Why Choose the ABB DS202CRB25A30 RCBO?
The ABB DS202CRB25A30 is a high-performance 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against overloads, short circuits and earth leakage faults. As part of the ABB DS200 / System pro M compact range, it combines overcurrent and residual-current protection in a single modular device for residential, commercial and industrial electrical distribution systems.
This RCBO features a 25 A rated current, B tripping characteristic and 30 mA Type A residual-current protection. Type A technology detects sinusoidal AC residual currents as well as pulsating DC residual currents, making the DS202CRB25A30 suitable for modern circuits supplying equipment containing electronic components.
The 2-pole configuration enables simultaneous switching of both conductors. Combined with its B-curve overcurrent characteristic and 30 mA residual-current sensitivity, the DS202CRB25A30 provides comprehensive protection for final circuits requiring dependable overcurrent and earth-leakage protection.

Reliable Type A Residual-Current Protection
RCBOs such as the ABB DS202CRB25A30 combine the functions of a miniature circuit breaker and a residual-current device. This allows one protective device to respond to overload and short-circuit conditions while also detecting residual currents caused by insulation faults and other earth-leakage conditions.
Type A residual-current protection responds to conventional sinusoidal AC leakage currents as well as pulsating DC residual currents. This capability makes Type A RCBOs particularly useful in modern installations where electronic power supplies, rectifiers and other semiconductor-based equipment can produce residual-current waveforms beyond those detected by Type AC devices.
Typical Applications
- Residential electrical distribution systems.
- Commercial final circuits and distribution boards.
- Industrial auxiliary and control circuits.
- Circuits supplying electronic equipment.
- Lighting and general-purpose electrical circuits.
- Building-services installations.
- Circuits requiring 30 mA Type A residual-current protection.
