Why Choose the ABB DS201K1A30 RCBO?
The ABB DS201K1A30 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 K tripping characteristic, a rated current of 1 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 according to IEC/EN 61009, the DS201K1A30 provides comprehensive circuit protection for residential, commercial and industrial installations. Its compact two-module 1P+N format enables straightforward installation in distribution boards and electrical control panels.

Reliable Combined Circuit Protection
RCBOs such as the ABB DS201K1A30 combine miniature circuit-breaker and residual-current protection in one compact device. This allows 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 protection against sinusoidal alternating and pulsating DC earth fault currents, while the K tripping characteristic is designed for circuits where transient or starting currents may occur. The DS201 series is suitable for residential, commercial and industrial electrical installations requiring dependable single-phase circuit protection.
Typical Applications
- Single-phase electrical distribution circuits.
- Residential and commercial distribution boards.
- Industrial electrical installations.
- Machinery and control-panel circuits.
- Low-current circuits requiring 1 A overcurrent protection.
- Circuits requiring 30 mA Type A residual-current protection.
