Why Choose the ABB DS201B20AC30 RCBO?
The ABB DS201B20AC30, manufacturer type DS201 B20 AC30, is a compact 1P+N Type AC residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth leakage faults. As part of the proven ABB DS200 series, it combines miniature circuit breaker and residual-current protection functions in a single DIN-rail device.
This RCBO has a 20 A rated current, B tripping characteristic and 30 mA rated residual operating current. Its Type AC residual-current characteristic is designed to detect sinusoidal alternating residual currents, while the B curve is suited to circuits with relatively low starting and inrush currents.
With a 1P+N configuration and a 6 kA rated short-circuit breaking capacity, the DS201 B20 AC30 provides dependable protection for single-phase final circuits while combining multiple protective functions in a compact modular device.

Combined Circuit and Residual-Current Protection
An RCBO combines the functions of a miniature circuit breaker and a residual-current protective device. The ABB DS201 B20 AC30 therefore protects a circuit against overload and short-circuit currents while also detecting residual earth leakage that can create electric-shock and electrically initiated fire hazards.
The Type AC residual-current characteristic responds to sinusoidal alternating residual currents, while the B curve provides overcurrent protection suited to circuits with relatively low starting currents. Combining these protective functions in one device helps simplify electrical distribution-board design and installation.
Typical Applications
- Single-phase electrical distribution boards.
- Residential electrical installations.
- Commercial electrical installations.
- Lighting and general power circuits.
- General-purpose circuits with relatively low inrush currents.
- Circuits requiring combined overload, short-circuit and earth leakage protection.
