Why Choose the ABB DS201 M C20 APR100 RCBO?
The ABB DS201 M C20 APR100 is a high-immunity 1P+N Type A APR residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase circuits against overloads, short circuits and residual earth fault currents. As part of the established ABB DS200 / DSH200 RCBO product group, it combines residual current and overcurrent protection within a compact two-module DIN-rail device for residential, commercial and industrial electrical installations.
ABB's APR high-immunity technology provides increased resistance to unwanted tripping, helping maintain continuity of service where transient disturbances may otherwise cause unnecessary circuit interruption. The Type A characteristic detects sinusoidal AC and pulsating DC residual currents, while the C tripping characteristic is suitable for circuits with moderate starting and inrush currents.
With a rated current of 20 A, a rated residual operating current of 100 mA and a rated short-circuit breaking capacity of 10 kA, the DS201 M C20 APR100 provides robust combined circuit protection. Its 230–240 V AC rated operational voltage and compact 1P+N configuration make it suitable for compatible single-phase circuits where dependable protection and increased resistance to unwanted tripping are required.

High-Immunity Combined Circuit and Residual Current Protection
RCBOs such as the ABB DS201 M combine miniature circuit-breaker and residual current protection functions within a single device. The DS201 M C20 APR100 can disconnect the protected circuit in response to overload, short-circuit or qualifying residual earth fault currents, helping simplify distribution-board design by providing these protective functions within one compact DIN-rail unit.
The APR high-immunity characteristic is designed to provide an effective balance between electrical protection and continuity of service through increased resistance to unwanted tripping. Combined with Type A residual current detection and a C curve overcurrent characteristic, the DS201 M C20 APR100 is well suited to compatible resistive and inductive loads where reliable operation during transient disturbances is important.
Typical Applications
- Residential electrical distribution systems.
- Commercial building electrical installations.
- Industrial single-phase circuits.
- Circuits where increased resistance to unwanted tripping is beneficial.
- Compatible resistive and inductive electrical loads.
- Circuits with moderate starting or inrush currents.
- Single-phase circuits requiring combined overcurrent and 100 mA residual earth fault protection.
