Why Choose the ABB DS201T B25 APR30 RCBO?
The ABB DS201T B25 APR30 is a compact and dependable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase electrical circuits against overloads, short circuits and residual earth fault currents. As part of the ABB DS200 / DSH200 RCBO family, it combines residual-current and overcurrent protection in a single modular device for efficient circuit protection.
This RCBO combines the functions normally provided by a miniature circuit breaker and residual-current protective device. Its APR residual-current characteristic provides enhanced resistance to unwanted tripping caused by transient disturbances, helping maintain continuity of service while providing dependable protection against relevant earth leakage currents.
With a rated current of 25 A, a B tripping characteristic, 30 mA residual-current sensitivity and a 6 kA rated short-circuit breaking capacity, the DS201T B25 APR30 provides comprehensive protection for suitable single-phase circuits. Its 1P+N configuration enables compact installation in modular electrical distribution systems.
Key Advantages
- Combines residual-current, overload and short-circuit protection in one device.
- 25 A rated current for single-phase circuit protection.
- B tripping characteristic suitable for circuits with relatively low starting currents.
- 30 mA residual-current sensitivity for additional protection against electric shock.
- 6 kA rated short-circuit breaking capacity.
- APR characteristic provides enhanced resistance to unwanted tripping.
Key Features
- ABB DS201T RCBO series.
- 1P+N configuration.
- 25 A rated current.
- B tripping characteristic.
- 30 mA rated residual operating current.
- APR residual-current characteristic for improved continuity of service.

Reliable Combined Circuit Protection
RCBOs combine miniature circuit breaker and residual-current protection within a single device. They disconnect the protected circuit in response to excessive current caused by an overload or short circuit while also detecting residual earth leakage, providing comprehensive electrical protection in a compact format.
The ABB DS201T B25 APR30 combines a B-curve overcurrent characteristic with APR residual-current protection. The B characteristic is well suited to circuits with relatively low inrush currents, while the APR design improves immunity to transient disturbances that could otherwise cause unnecessary circuit interruptions.
Typical Applications
- Single-phase final circuits.
- Electrical distribution boards.
- Control and auxiliary circuits.
- Resistive electrical loads.
- Commercial and industrial electrical installations.
- Applications requiring combined overcurrent and residual-current protection.
