Why Choose the ABB DS201T C40 APR30 RCBO?
The ABB DS201T C40 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 electrical distribution and 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 residual-current protection.
With a rated current of 40 A, a C tripping characteristic, 30 mA residual-current sensitivity and a 6 kA rated short-circuit breaking capacity, the DS201T C40 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.
- 40 A rated current for single-phase circuit protection.
- C tripping characteristic suitable for loads with moderate starting currents.

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 C40 APR30 combines a C-curve overcurrent characteristic with APR residual-current protection. The C characteristic accommodates moderate equipment starting 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.
- Commercial and industrial electrical installations.
- Circuits with moderate equipment starting currents.
- Applications requiring combined overcurrent and residual-current protection.
