Why Choose the ABB DS201MB32A300 RCBO?
The ABB DS201MB32A300 is a compact and reliable residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase circuits against overloads, short circuits and earth leakage faults. Part of the ABB DS201 M series, it combines miniature circuit breaker and residual current protection functions within a single modular device.
This RCBO features a 32 A rated current, Type B tripping characteristic and Type A residual current detection. Type A protection responds to sinusoidal AC residual currents and pulsating DC residual currents, making the DS201MB32A300 suitable for electrical circuits containing conventional and electronic loads.
With a 300 mA rated residual operating current and 10 kA rated short-circuit breaking capacity, the DS201MB32A300 provides dependable combined protection for conductors and connected equipment. Its 1P+N configuration switches both line and neutral, with overcurrent protection provided on the line pole.
Key Advantages
- Combines overcurrent and residual current protection in one compact RCBO.
- 32 A rated current for single-phase circuit protection.
- 300 mA residual current sensitivity for earth leakage protection.

Reliable Combined Circuit and Residual Current Protection
RCBOs such as the ABB DS201MB32A300 combine thermal-magnetic overcurrent protection with residual current protection in a single modular device. This enables an individual circuit to be protected against overloads, short circuits and earth leakage faults without requiring separate miniature circuit breaker and residual current circuit breaker devices.
The DS201 M Type A design detects sinusoidal AC and pulsating DC residual currents, while the B-curve characteristic is suited to circuits with relatively low normal inrush currents. Its 300 mA residual operating threshold provides earth leakage protection for applications specified for this sensitivity.
Typical Applications
- Commercial electrical distribution boards.
- Industrial auxiliary and power circuits.
- Building-services electrical circuits.
- General-purpose single-phase electrical loads.
- Circuits with relatively low starting or inrush currents.
- Circuits requiring Type A 300 mA residual current protection.
