Why Choose the ABB FS401MK-C25/0.03 RCBO?
The ABB FS401MK-C25/0.03 is a compact and dependable 1P+N Type F residual current circuit breaker with overcurrent protection (RCBO) designed for the ABB SMISSLINE TP plug-in system. It combines overload, short-circuit and residual-current protection in a single device, providing comprehensive protection for single-phase final circuits in residential, commercial and industrial electrical installations.
This FS401MK model has a 25 A rated current, C tripping characteristic and 30 mA rated residual operating current. Its Type F, short-time-delayed residual-current protection provides resistance to unwanted tripping while protecting against sinusoidal AC and pulsating DC earth-fault currents, making it well suited to modern electrical loads.
With a rated voltage of 240 V and a 10 kA rated short-circuit breaking capacity, the FS401MK-C25/0.03 provides robust circuit protection in a compact two-module format. The integrated DTI earth-fault indication assists fault identification, while the plug-in design enables efficient installation within ABB SMISSLINE TP distribution systems.

Reliable Combined Circuit and Residual-Current Protection
An RCBO combines miniature circuit-breaker and residual-current protection within a single device. The ABB FS401MK-C25/0.03 therefore protects connected circuits against overload and short-circuit currents while also detecting earth-fault currents, providing protection against indirect contact and additional protection against direct contact at its 30 mA residual-current rating.
The Type F, short-time-delayed design provides increased resistance to unwanted tripping and supports continuity of service while protecting resistive and inductive loads. Integration with ABB's SMISSLINE TP plug-in architecture also enables efficient distribution-board assembly, maintenance and circuit replacement.
Typical Applications
- Single-phase final circuits in SMISSLINE TP distribution boards.
- Residential electrical distribution systems.
- Commercial buildings and office installations.
- Industrial electrical distribution systems.
- Circuits supplying modern electronic equipment.
- Resistive and inductive loads requiring combined overcurrent and residual-current protection.
