Why Choose the ABB DS201B40AC300 RCBO?
The ABB DS201B40AC300 is a compact and reliable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase circuits against overloads, short circuits and sinusoidal AC earth leakage currents. As part of the ABB DS201 series, it combines residual-current and overcurrent protection in a compact two-module device for efficient electrical distribution and circuit protection.
This RCBO features a Type B tripping characteristic, a rated current of 40 A and Type AC residual-current detection. Its 300 mA rated residual operating current provides earth-fault protection for applications where this sensitivity is specified, while integrated thermal-magnetic protection safeguards conductors and connected equipment against overload and short-circuit conditions.
With a rated short-circuit capacity of 6 kA and a 1P+N configuration, the DS201B40AC300 is suited to single-phase electrical distribution systems in residential, commercial and industrial installations. Its DIN-rail format helps simplify panel installation while combining two essential protective functions within one device.

Combined Residual-Current and Overcurrent Protection
RCBOs such as the ABB DS201 combine the functions of a miniature circuit breaker and a residual-current protective device. This enables a single device to protect a circuit against overload and short-circuit currents while also detecting earth leakage caused by sinusoidal alternating residual currents.
The DS201 series is designed for compact electrical distribution systems where individual circuits require dedicated protection. Integrating residual-current and overcurrent protection into one DIN-rail device helps simplify distribution-board design, installation and fault isolation.
Typical Applications
- Single-phase electrical distribution circuits.
- Residential and commercial distribution boards.
- Industrial electrical distribution systems.
- Building electrical installations.
- Circuits requiring combined overload, short-circuit and earth-fault protection.
- DIN-rail electrical panels and distribution equipment.
