Why Choose the ABB DS201 B40 A30 RCBO?
The ABB DS201 B40 A30 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. As part of the advanced ABB DS201 RCBO series, it combines residual current and overcurrent protection in a single modular device for efficient electrical distribution and final-circuit protection.
This RCBO provides a 40 A rated current, B tripping characteristic and 30 mA Type A residual current sensitivity. Type A residual current protection detects sinusoidal AC and pulsating DC residual currents, making the device suitable for modern circuits containing electronic equipment and other loads capable of producing pulsating DC fault currents.
With a 1P+N configuration, 230 V AC rated voltage and 6 kA rated short-circuit breaking capacity, the DS201 B40 A30 provides comprehensive protection in a compact two-module DIN-rail format. ABB order code 2CSR255180R1405 identifies this specific 40 A, B-curve, Type A, 30 mA version.

Combined Residual Current and Overcurrent Protection
RCBOs such as the ABB DS201 combine the functions of a miniature circuit breaker and a residual current protective device. The DS201 B40 A30 therefore protects the connected circuit against overload and short-circuit currents while also disconnecting the supply when a hazardous residual current to earth is detected.
The Type A residual current characteristic provides protection against sinusoidal alternating and pulsating direct residual currents. Its 30 mA sensitivity provides additional protection against electric shock, while the B tripping characteristic is well suited to conventional resistive and general-purpose electrical loads with relatively low starting currents.
Typical Applications
- Residential single-phase final circuits.
- Commercial electrical distribution boards.
- Socket outlet and general power circuits.
- Lighting and building-services circuits.
- Circuits supplying electronic and single-phase equipment.
- Control panels and light industrial distribution systems.
