Why Choose the ABB DS201K8A300 RCBO?
The ABB DS201K8A300 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 fault currents. As part of the ABB DS201 series, it combines residual-current and overcurrent protection in one DIN rail device for residential, commercial and industrial electrical installations.
This RCBO features an 8 A rated current, K tripping characteristic and Type A residual-current detection. Type A protection detects sinusoidal AC and pulsating DC residual currents, while the K characteristic provides overcurrent protection suitable for circuits and equipment with higher starting currents.
With a rated residual operating current of 300 mA and a rated short-circuit capacity of 6 kA, the DS201K8A300 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 electrical 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 DS201K8A300 protects single-phase circuits against overload and short-circuit currents while monitoring for residual currents to earth, providing comprehensive electrical 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 makes it particularly useful for circuits containing equipment that can produce higher starting currents while still requiring dependable overload and short-circuit protection.
Typical Applications
- Residential electrical distribution boards.
- Commercial building electrical installations.
- Industrial distribution and control panels.
- Single-phase branch circuit protection.
- Circuits supplying equipment with higher starting currents.
- Installations requiring Type A residual-current detection.
