Why Choose the ABB DS201MB25AC30 RCBO?
The ABB DS201MB25AC30, manufacturer type DS201 M B25 AC30, is a compact and reliable 1P+N 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 ABB DS200 / DS201 M series, it combines residual current and overcurrent protection within a compact DIN-rail device for single-phase final circuits.
This RCBO has a rated current of 25 A, a Type B tripping characteristic and a rated residual operating current of 30 mA. Its Type AC residual current characteristic is designed to detect sinusoidal alternating residual currents, providing residual current protection for suitable conventional AC electrical loads.
With a rated voltage of 230 V AC and a rated short-circuit capacity of 10 kA, the DS201 M B25 AC30 provides robust protection for single-phase electrical distribution applications. Its compact 1P+N configuration helps conserve space in distribution boards while combining overload, short-circuit and residual current protection in one device.
Key Advantages
- Combined residual current and overcurrent protection in one RCBO.
- 25 A rated current for suitable single-phase final circuits.
- 30 mA residual current sensitivity for additional protection against electric shock.
- Type AC residual current detection for sinusoidal alternating residual currents.
- Type B tripping characteristic suited to circuits with relatively low inrush currents.
- 10 kA rated short-circuit capacity for robust circuit protection.
- Compact 1P+N configuration for efficient use of distribution board space.
- Suitable for residential, commercial and industrial electrical installations.

Reliable Protection for Single-Phase Final Circuits
An RCBO combines residual current protection with overload and short-circuit protection in a single device. The ABB DS201 M B25 AC30 monitors the protected circuit for sinusoidal alternating earth leakage currents while also disconnecting the circuit when excessive current occurs because of an overload or short circuit.
The 30 mA residual current sensitivity provides additional protection against electric shock, while the B-curve overcurrent characteristic is suited to circuits where substantial starting currents are not normally expected. The compact 1P+N format makes the DS201 M B25 AC30 suitable for a broad range of single-phase final circuits.
Typical Applications
- Residential single-phase final circuits.
- Commercial electrical distribution boards.
- Lighting and general-purpose electrical circuits.
- Industrial single-phase auxiliary circuits.
- Circuits requiring 30 mA residual current protection.
- Installations requiring combined overload, short-circuit and earth leakage protection.
