Why Choose the ABB DS201K6A300 RCBO?
The ABB DS201K6A300 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 earth leakage faults. As part of the ABB DS201 series, it combines residual current and overcurrent protection in a single two-module DIN rail device for residential, commercial and industrial electrical installations.
This RCBO features a 6 A rated current, K tripping characteristic and Type A residual current detection. Type A protection detects sinusoidal AC residual currents and pulsating DC residual currents, making the device suitable for circuits supplying modern electrical and electronic equipment.
With a rated residual operating current of 300 mA and a rated short-circuit capacity of 6 kA according to IEC/EN 61009, the DS201K6A300 provides combined circuit and residual-current protection in a compact format. Its 1P+N configuration, DIN rail mounting and screw terminals support straightforward integration into distribution boards and control panels.

Combined Circuit and Residual-Current Protection
RCBOs combine the functions of a miniature circuit breaker and a residual current device in one unit. The ABB DS201K6A300 protects single-phase circuits against overload and short-circuit currents while monitoring for residual currents to earth, helping provide comprehensive protection within a compact distribution-board footprint.
The Type A residual-current characteristic allows the device to respond to sinusoidal AC and pulsating DC residual currents. Its K tripping characteristic provides defined overcurrent protection for circuits where the connected load characteristics require a K-curve protective device.
Typical Applications
- Residential electrical distribution boards.
- Commercial building electrical installations.
- Industrial distribution and control panels.
- Single-phase branch circuit protection.
- Circuits requiring Type A residual-current detection.
- Electrical installations requiring combined overload, short-circuit and earth leakage protection.
