Why Choose the ABB DS201MC40APR300 RCBO?
The ABB DS201MC40APR300 is a compact and reliable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and residual earth fault currents. Part of the ABB DS201 M / System pro M compact range, it combines residual-current and overcurrent protection in a two-module-width device for single-phase electrical circuits.
With a rated current of 40 A, C tripping characteristic and 300 mA rated residual operating current, the DS201 M C40 APR300 provides coordinated protection for electrical distribution applications. Its Type A residual-current detection responds to sinusoidal AC and pulsating DC residual currents, making it suitable for circuits supplying modern electrical and electronic loads.
The APR high-immunity characteristic provides increased resistance to unwanted tripping, supporting improved continuity of service while maintaining effective residual-current protection. The DS201MC40APR300 has a 10 kA rated short-circuit breaking capacity, a 230–240 V AC rated operational voltage and standard 35 mm DIN-rail mounting for straightforward integration into distribution boards and control panels.

Reliable Combined Circuit and Residual-Current Protection
An RCBO combines overcurrent and residual-current protection within a single modular device. The ABB DS201MC40APR300 protects connected circuits against overload and short-circuit currents while detecting residual earth fault currents that can result from insulation faults or leakage to earth.
The Type A APR characteristic extends residual-current detection to sinusoidal alternating and pulsating DC fault currents. ABB's APR high-immunity technology also increases resistance to unwanted tripping caused by transient disturbances, providing a practical balance between electrical protection and continuity of service for resistive and inductive loads.
Typical Applications
- Single-phase electrical distribution circuits.
- Commercial and industrial distribution boards.
- Electrical control panels and machinery supplies.
- Circuits supplying resistive and inductive loads.
- Installations containing electronic equipment capable of producing pulsating DC residual currents.
- Applications requiring improved resistance to unwanted residual-current tripping.
