Why Choose the ABB DS201 M B25 A300 RCBO?
The ABB DS201 M B25 A300 is a compact and dependable 1P+N Type A residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and residual earth leakage faults. As part of the established ABB DS200 / DSH200 RCBO product group, it combines residual current and overcurrent protection within a single DIN-rail device for residential, commercial and industrial electrical installations.
This RCBO provides Type A residual current protection, enabling detection of sinusoidal AC residual currents and pulsating DC residual currents. Its B tripping characteristic is suited to circuits where relatively low starting and inrush currents are expected, while the combined RCBO design provides multiple protective functions within one compact device.
With a rated current of 25 A, a rated residual operating current of 300 mA and a rated voltage of 230 V AC, the DS201 M B25 A300 provides robust protection for compatible single-phase circuits. The device features a 1P+N configuration and a 10 kA short-circuit breaking capacity, making it suitable for demanding electrical distribution applications.

Reliable Combined Circuit and Residual Current Protection
RCBOs such as the ABB DS201 M combine the functions of a miniature circuit breaker and residual current device within a single protective unit. The DS201 M B25 A300 can disconnect the protected circuit in response to overload, short-circuit or qualifying residual earth leakage currents, providing coordinated protection while reducing the need for separate protective devices.
The Type A residual current characteristic enables the DS201 M B25 A300 to respond to sinusoidal alternating residual currents as well as pulsating DC residual currents. Combined with its B curve overcurrent characteristic and 10 kA short-circuit breaking capacity, this makes the RCBO suitable for a broad range of residential, commercial and industrial single-phase electrical circuits.
Typical Applications
- Residential electrical distribution boards.
- Commercial building electrical installations.
- Industrial single-phase final circuits.
- Lighting and general electrical circuits.
- Control and auxiliary circuits.
- Circuits with relatively low starting and inrush currents.
- Distribution circuits requiring combined overcurrent and earth leakage protection.
