Why Choose the ABB DS201C20A30 RCBO?
The ABB DS201C20A30 is a compact and reliable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase electrical circuits against overloads, short circuits and residual earth leakage currents. As part of the ABB DS200 / DSH200 RCBO range, it combines residual-current and overcurrent protection within a single DIN-rail mounted device.
This RCBO features a C tripping characteristic, a rated current of 20 A and Type A residual-current protection with a rated sensitivity of 30 mA. Type A protection detects sinusoidal AC residual currents as well as pulsating DC residual currents, making the device suitable for a broad range of modern electrical loads.
With a rated operating voltage of 230–240 V AC and a rated short-circuit breaking capacity of 6 kA, the DS201C20A30 provides comprehensive protection for residential, commercial and industrial electrical installations. Its compact 1P+N DIN-rail format enables straightforward installation in distribution boards and electrical control panels.

Reliable Combined Circuit Protection
RCBOs such as the ABB DS201C20A30 combine miniature circuit-breaker and residual-current protection in one compact device. This enables the connected circuit to be protected against overload and short-circuit currents while simultaneously detecting potentially hazardous residual currents flowing to earth.
The Type A residual-current characteristic provides detection of sinusoidal alternating and pulsating DC residual currents, while the C tripping characteristic is suitable for many general-purpose circuits with moderate starting currents. The DS201 series provides dependable individual circuit protection for modern residential, commercial and industrial electrical distribution systems.
Typical Applications
- Single-phase electrical distribution circuits.
- Residential and commercial distribution boards.
- General-purpose final circuits.
- Industrial electrical installations.
- Machinery and electrical control-panel circuits.
- Circuits requiring 30 mA Type A residual-current protection.
