Why Choose the ABB DSE201 B10 A30 RCBO?
The ABB DSE201 B10 A30 is a compact residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and residual earth leakage currents. As part of the ABB DSE201 6 kA RCBO series, it combines residual-current and overcurrent protection in one modular device for residential and light-commercial electrical installations.
This RCBO features a 10 A rated current, B tripping characteristic and 30 mA rated residual operating current. Its Type A residual-current protection detects sinusoidal alternating residual currents as well as pulsating DC residual currents, providing broader fault-current detection than an AC-type device.
With a 6 kA rated short-circuit breaking capacity and compact 1P+N configuration, the DSE201 B10 A30 provides comprehensive circuit protection while conserving valuable distribution-board space. Its B characteristic is well suited to conventional circuits with relatively low inrush currents, including appropriately designed lighting and general final circuits.
Key Advantages
- Combined residual-current and overcurrent protection in one compact RCBO.
- 10 A rated current for appropriately rated single-phase final circuits.

Reliable Type A Protection for Final Circuits
An RCBO combines the functions of a miniature circuit breaker and residual-current protective device in one unit. The ABB DSE201 B10 A30 therefore protects the circuit against excessive current caused by overloads or short circuits while also disconnecting the supply when qualifying residual earth leakage reaches the device's operating threshold.
The 30 mA Type A residual-current protection responds to sinusoidal AC and pulsating DC residual currents, making it suitable for circuits supplying many types of modern electrical and electronic equipment. Combined with its B-characteristic thermal-magnetic protection, the DSE201 B10 A30 provides a compact solution for appropriately rated single-phase final circuits.
Typical Applications
- Residential electrical distribution boards.
- Light-commercial electrical installations.
- Single-phase final circuits.
- Lighting circuits.
- Circuits supplying modern electronic equipment.
- General low-inrush electrical loads.
- Compact modular distribution assemblies.
