Why Choose the ABB DS201 M B40 A100 RCBO?
The ABB DS201 M B40 A100 is a high-performance 1P+N Type A residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and earth leakage faults. As part of the established ABB DS200 / DSH200 RCBO product group, it combines residual current and overcurrent protection within one compact 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 provides rapid magnetic operation at relatively low multiples of rated current, making it particularly suitable for circuits without high starting or inrush currents.
With a rated current of 40 A, a rated residual operating current of 100 mA and a 230 V AC rated voltage, the DS201 M B40 A100 provides dependable combined protection for single-phase circuits. The DS201 M range offers a 10 kA short-circuit breaking capacity, while the 1P+N configuration provides protection of the phase conductor together with neutral switching.

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 B40 A100 can disconnect the protected circuit in response to overload, short-circuit or qualifying residual earth leakage currents, providing coordinated protection without requiring separate MCB and RCD devices for the circuit.
The Type A residual current characteristic enables the DS201 M B40 A100 to detect sinusoidal alternating residual currents as well as pulsating DC residual currents. Combined with its B curve overcurrent characteristic and 10 kA breaking capacity, this makes it a practical solution for modern single-phase electrical installations where dependable combined circuit protection is required.
Typical Applications
- Residential electrical distribution boards.
- Commercial building electrical installations.
- Industrial single-phase final circuits.
- Lighting and general-purpose electrical circuits.
- Circuits with low starting and inrush currents.
- Distribution circuits requiring combined overcurrent and earth leakage protection.
