Why Choose the ABB DS201MC25APR30 RCBO?
The ABB DS201MC25APR30 is a compact residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase circuits against overloads, short circuits and residual current faults. Part of the ABB DS201 M series, it combines overcurrent and residual current protection within a single modular device.
This RCBO features a 25 A rated current, Type C tripping characteristic and ABB APR residual current protection. The APR design provides increased resistance to unwanted tripping caused by transient disturbances compared with conventional instantaneous residual current protection, helping improve service continuity in suitable installations.
With a 30 mA rated residual operating current and 10 kA rated short-circuit breaking capacity, the DS201MC25APR30 provides dependable combined circuit protection. Its 1P+N configuration switches both line and neutral, with overcurrent protection provided on the line pole.
Key Advantages
- Combines overcurrent and residual current protection in one compact RCBO.
- 25 A rated current for single-phase circuit protection.
- 30 mA residual current sensitivity for sensitive earth leakage protection.

Reliable Protection with Enhanced Continuity
RCBOs such as the ABB DS201MC25APR30 combine thermal-magnetic overcurrent protection with residual current protection in a single modular device. This enables an individual circuit to be protected against overloads, short circuits and earth leakage faults without requiring separate miniature circuit breaker and residual current circuit breaker devices.
The APR characteristic is designed to improve immunity to unwanted residual current tripping associated with transient disturbances, while the C-curve overcurrent characteristic accommodates moderate starting currents. Combined with its 30 mA residual operating threshold, the DS201MC25APR30 is suited to circuits where sensitive residual current protection and improved continuity are required.
Typical Applications
- Commercial electrical distribution boards.
- Industrial auxiliary and power circuits.
- Building-services electrical circuits.
- Single-phase equipment circuits with moderate starting currents.
- Circuits where transient disturbances may otherwise contribute to unwanted tripping.
- Applications requiring APR 30 mA residual current protection.
