Why Choose the ABB FS401MB200.03 RCBO?
The ABB FS401MB200.03, type code FS401M-B20/0.03, is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and residual earth fault currents. As part of the ABB FS401M series for the SMISSLINE TP plug-in system, it combines overcurrent and residual current protection in one modular protective device for residential, commercial and industrial installations.
This RCBO has a 20 A rated current, B tripping characteristic and 30 mA Type A residual current sensitivity. Type A residual current protection responds to sinusoidal AC and pulsating DC earth fault currents, while the 30 mA sensitivity provides protection against indirect contact and additional protection against direct contact.
With a 10 kA rated short-circuit breaking capacity according to IEC/EN 61009-1, the FS401M-B20/0.03 provides robust combined protection in a compact two-module format. Its direct SMISSLINE TP plug-in connection supports efficient installation, replacement and circuit configuration within compatible ABB distribution assemblies.

Reliable Combined Circuit and Residual Current Protection
The ABB FS401M-B20/0.03 combines miniature circuit breaker and residual current protective functions in a single device. It protects a single-phase final circuit against overload and short-circuit currents while monitoring for residual currents caused by earth faults, reducing the need for separate overcurrent and residual current protective devices.
Its Type A 30 mA residual current protection responds to sinusoidal AC and pulsating DC earth fault currents, while its 10 kA short-circuit breaking capacity provides robust fault protection. Direct connection to the SMISSLINE TP plug-in system supports efficient installation, maintenance and flexible circuit configuration within compatible ABB assemblies.
Typical Applications
- Single-phase final circuit protection.
- Residential electrical distribution systems.
- Commercial building electrical installations.
- Industrial control and auxiliary circuits.
- Building services and general-purpose circuits.
- Circuits requiring 10 kA short-circuit breaking capacity.
- ABB SMISSLINE TP plug-in distribution systems.
