Why Choose the ABB DS201MC32APR300 RCBO?
The ABB DS201MC32APR300 is a compact and dependable 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, this device combines miniature circuit-breaker and residual-current protection functions within a two-module-width unit for single-phase final circuits.
With a rated current of 32 A, C tripping characteristic and 300 mA rated residual operating current, the DS201 M C32 APR300 is suitable for electrical distribution applications requiring coordinated overcurrent and earth-leakage protection. Its Type A residual-current detection responds to sinusoidal AC and pulsating DC residual currents, supporting modern electrical loads containing electronic components.
The APR high-immunity design is engineered to improve continuity of service by providing enhanced resistance to unwanted tripping. The device has a 10 kA rated short-circuit breaking capacity (Icn), operates at 230–240 V AC and mounts on standard 35 mm DIN rail, making it well suited to professional distribution boards and industrial control installations.

Reliable Combined Circuit and Residual-Current Protection
An RCBO combines the functions of an overcurrent protective device and a residual-current protective device in a single modular unit. The ABB DS201MC32APR300 therefore protects the connected circuit against overload and short-circuit conditions while also detecting residual currents that can arise from insulation faults or leakage to earth.
The Type A APR characteristic is particularly useful where continuity of service is important. Type A detection provides protection against sinusoidal alternating and pulsating DC residual currents, while ABB's APR high-immunity design offers enhanced resistance to unwanted tripping caused by transient disturbances, helping maintain reliable operation of 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 where improved resistance to unwanted residual-current tripping is required.
