Why Choose the ABB DS202CRMB25A300 RCBO?
The ABB DS202CRMB25A300 is a compact and reliable 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to protect end-user single-phase circuits against overloads, short circuits and residual earth fault currents. As part of the ABB DS202CR M series, it combines residual current and overcurrent protection within a space-saving two-module device for residential, commercial and industrial electrical distribution systems.
This Type A RCBO detects sinusoidal alternating and pulsating DC residual currents, while its Type B tripping characteristic provides dependable overcurrent protection for circuits with relatively low inrush currents. The combined RCBO design simplifies electrical distribution by providing both overcurrent and residual current protection from a single DIN-rail mounted device.
With a rated current of 25 A, a rated residual operating current of 300 mA and a 10 kA rated short-circuit breaking capacity, the DS202CRMB25A300 provides robust protection in a compact format. ABB order code 2CSR772140R3255 identifies this specific DS202CR M Type A, B25 configuration.

Reliable Combined Protection for Electrical Circuits
RCBOs such as the ABB DS202CRMB25A300 combine miniature circuit breaker and residual current protection functions within a single device. The RCBO disconnects the protected circuit when overload or short-circuit conditions occur while also responding to residual earth fault currents, providing comprehensive electrical protection from one compact component.
The DS202CR series is designed for end-user single-phase circuits where dependable protection and efficient use of distribution-board space are important. Its Type A residual current characteristic responds to sinusoidal alternating and pulsating DC earth fault currents, while the Type B overcurrent characteristic is suited to circuits with relatively low starting currents.
Typical Applications
- Residential electrical distribution boards.
- Commercial building electrical installations.
- Industrial electrical distribution systems.
- End-user single-phase circuits requiring combined protection.
- Circuits requiring Type A residual current detection.
- General-purpose electrical loads with relatively low inrush currents.
- DIN-rail mounted modular distribution equipment.
